feat: bill the openrouter-auto router alias at actual upstream cost - #1012
Merged
Merged
Conversation
`openrouter/auto-beta` is a router: it picks a different upstream model per
request, so OpenRouter reports `prompt: -1, completion: -1` for it and there is
no fixed price to charge against. This adds the alias `openrouter-auto`
("Openrouter Auto (Task Aware)") and bills it at the cost OpenRouter reports for
each generation, times the standard 1.4 margin, instead of inventing a catalog
rate that would be wrong on nearly every request.
Schema. `model_aliases` gains `pricing_mode` (fixed | upstream_actual) and
`reservation_estimate_credits`; the two price columns become nullable, and a
CHECK binds all three so the database refuses an inconsistent row. The prices go
NULL rather than 0 deliberately: 0 already means "no cost basis" to
routing.Service and to the metering gate, and a price that silently reads 0 is
what billed nothing for three days in July. The Go readers scan these columns
into non-pointer int64, so a NULL is a hard scan error and any reader not taught
about variable pricing fails loudly instead of charging zero.
Settlement. The charge is derived in math/big from the reported cost, never
float64, reusing the same round-half-up discipline as the per-million path.
Absent, unparseable, negative and a confident zero alongside real tokens are
four distinct errors, and none of them settles at zero: they charge the full
hold flagged unconfirmed, which is bounded, loud, and routed into the existing
reconciliation state. The only path that charges nothing is the one where
nothing was produced.
Provider blindness. The owner deliberately named this alias after its provider,
so the alias name is not secret. The identity of the model the router actually
chose still is: the cost is parsed out of the raw upstream bytes into a private
struct rather than added to UsageResponse, which the normalize functions
re-marshal straight to the customer. The upstream generation id is recorded as
the audit handle, since it is what lets anyone recover the chosen model later.
Also fixes two places a nulled price would have gone unnoticed: the deploy-box
price assertion filtered on `input_price_credits > 0`, and `NULL > 0` is NULL,
so this route would have escaped the guard silently; and the admin catalog table
coerced a missing price to 0 and rendered it as free.
Not included, and required before this alias works in chat: the LiteLLM image
pin. Measured against the pinned v1.77.7-stable, the streaming terminal usage
chunk carries no cost at all, so every streamed request would take the
fail-closed path. That bump lands as its own change.

📝 WalkthroughWalkthroughChangesThe change introduces Upstream actual pricing
Estimated code review effort: 5 (Critical) | ~120 minutes Merge Risk: 🟠 High · up to This change introduces a customer-facing router whose billing depends on provider-reported cost, but the current head can lose streamed cost data, under-reserve requests, leave settlements incomplete after a panic, and expose provider metadata to clients. Those issues can cause incorrect charges, broken accounting, or data disclosure, so the PR is not merge-ready and should be blocked until fixed. Sequence Diagram(s)sequenceDiagram

Addresses the review findings on the first commit. The important one: `provider.max_price` bounds the per-million RATE and nothing else. It does not bound how many tokens one request may carry, and openrouter/auto-beta advertises a 2,000,000 token context, so a single large-context call could have cost around 6.00 USD of prompt alone, roughly 840,000 credits after margin, against a 200,000 credit hold. Settlement charges the reported cost rather than the hold, so that request would have settled several times past the solvency gate the hold is supposed to be. The reservation could under-reserve, which is one of the invariants this work is not allowed to break. Both sides of the request are now bounded before dispatch. The body is capped at 256 KiB, which is a rigorous upper bound of 262,144 prompt tokens because a token can never be fewer than one UTF-8 byte, and the completion ceiling is pinned at 16,384 tokens onto the outbound request so a client cannot raise it. A test computes the worst case across the three files that have to agree, the price ceiling in the LiteLLM config, the caps in Go, and the hold in the migration, and fails if the hold no longer covers it. It currently reads 144,507 credits against a 200,000 hold. Also corrects a claim that was simply wrong. A comment asserted that JSON null decoded into a non-pointer int64 would reject the payload. It does not: it is a documented no-op that leaves the field at zero and returns no error, verified against Go's own decoder rather than assumed. That makes the pointer change on the edge-api structs load-bearing rather than defensive, because the previous shape would have silently priced a variable-price alias at zero, which is indistinguishable from free. Third fix: the refusal log in requireTokenPricing still read the raw price fields, which are now pointers. fmt accepts %d for a pointer and prints the address, and go vet does not flag it because %d is legal for pointers, so the only operator-facing explanation of a refusal would have printed memory addresses. It uses the accessors now. Also builds the test pricing value in one literal instead of mutating it after assignment.

Evidence that these tests can actually failThis repo has a documented history of tests that are green but structurally incapable of going red, so every guard added here was checked by breaking the implementation in the exact way the guard exists to catch and confirming the test goes red. 13 mutations, 13 killed, zero survivors. Method: apply one mutation to the source, run only the targeted test in the toolchain container, require FAIL, restore. Harness and full output are reproducible; the mutation list is below. Arithmetic and guard logic
Wiring, which is the half that stays invisible while unit tests are green
Two deliberate choices about assertion shapeBoth exist because the obvious assertion would have been satisfied by the bug. No assertion is of the form "credits > 0". A broken conversion prices every token at zero and then hits the 1-credit floor, so "non-zero" passes on exactly the near-free outcome being guarded against. Every magnitude assertion is an exact figure derived longhand from a known upstream cost: 0.0123456 USD x 1.4 x 100000 = 1728.384, so 1728. That figure is also nowhere near the token count (1500) or the hold (200000), so a regression into either shape fails rather than sliding past. A test of my own was fixed after it was written. On the timeout caseThe brief asked for the free-serve guard to be proved against three separate cases: the cost lookup returns null, errors, and times out. The first two are direct. The third needs stating honestly rather than faked: the cost is carried in band on the response, so there is no separate call that can time out. What a timeout or an aborted stream actually produces on this path is no usage frame at all, and therefore no bytes to read. It is tested that way, as the empty-body case, rather than by inventing a network timeout that does not exist in the design. |

Go review: BLOCKReviewed the pushed diff at The design is right and the reasoning in the comments is unusually good. What is wrong is wiring, and in two places the wiring defeats the exact guard the feature is built around. CRITICAL1. The test suite cannot see it: 2. HIGH3. 4. 5. The hold is not a ceiling. The derivation assumes a 30k/4k request; the same route advertises 2000000 context. At MEDIUM
LOWThree call sites duplicate the same fifteen line branch, and two of the three are the bugs above. The audio adapter refusal is correct but redundant, Where I found nothingSaid explicitly, since these were the questions asked.
To unblockFix CRITICAL 1 and 2 and HIGH 3, and add a range check for HIGH 4. Each of the three has a specific missing test named in its inline comment, and I would want those too, because all three are the kind of defect the current suite is shaped to pass over. |

Database review (money path), head
|
| Severity | Finding | Where |
|---|---|---|
| CRITICAL | extra_body.usage.include and provider.max_price never reach the running LiteLLM on the demo box, because the live config is a first boot seeded volume and the only other writer is the DB driven sync, which emits three keys and not these. Without the first, every request settles at the full 200000 credit hold. Without the second, the new hold covers the worst case guard is arithmetic about a ceiling that is not enforced in production. |
deploy/litellm/config.yaml:202 |
| MEDIUM | The hold's stated derivation (about 21000 credits, "an order of magnitude above") is superseded by TestTheHoldProvablyCoversTheWorstBoundedRequest, whose real bound is 144507 with about 28 percent headroom. Two live consequences of the value: a 2.00 USD minimum balance is now required to use the alias at all, and the fail closed branch charges the worst case figure for a request that may have cost a thousandth of it. |
migration :136 |
| MEDIUM | on conflict (alias_id) do nothing is correct for a re-run and silent for a collision. With other same-day migrations landing that also insert aliases, a colliding openrouter-auto seeded as fixed first leaves a variable cost model billed at a fixed price with no error anywhere. A four line assertion closes it. |
migration :138 |
| MEDIUM | No begin;. The NOT NULL drop and the shape CHECK that replaces it are separated, so a hand applied psql -f that aborts in between leaves the money table with neither. 48 of 91 migrations here already wrap. |
migration :56 |
| MEDIUM | pricing_mode was added to the wire contract but neither catalog/http.go nor catalog/service.go populates it, so the catalog API always emits "pricing_mode": "". Not a charging bug (the money path reads it via routing), but web-console decodes it and falls back to fixed, so the admin catalog labels the variable alias as fixed. |
catalog/types.go:104 |
| LOW | The shape CHECK does not cover cache_read_price_credits / cache_write_price_credits, so an upstream_actual row can still carry the stale number the header says the constraint forbids. |
migration :82 |
| LOW | Nullable prices make the existing model_aliases_single_unit_price CHECK evaluate to NULL, and so pass, for a non token upstream_actual row. Latent only: both consumers refuse on the mode first. |
migration :69 |
| LOW | No lock_timeout in front of six ACCESS EXCLUSIVE statements on a table read once per request. Duration is not the exposure, queueing is. |

| LOW | formatPrice renders "Variable" for a missing price as well as a variable one, and ignores the pricing_mode decoded next to it. |

Where I found nothing, stated explicitly
- The shape CHECK is correct. Full truth table worked, and three valued logic does not bite it.
pricing_modeis NOT NULL with a default and a domain CHECK so it is never NULL; every nullable sensitive test isIS NULLorIS NOT NULL, which are two valued; and the one comparison that could go unknown,reservation_estimate_credits > 0, shares its conjunction withreservation_estimate_credits is not null, which is false in exactly the case the comparison is NULL, and FALSE AND NULL is FALSE. So the expression is boolean definite for every row. It rejects all of: fixed with either price NULL, fixed carrying a reservation, upstream_actual with either price set, upstream_actual with no reservation, upstream_actual with a zero or negative reservation. Only the two intended shapes pass. - It cannot fail validation against existing rows. Every pre-existing row takes
pricing_mode = 'fixed'from the column default (fast default, PG 11 and later, no rewrite), has non NULL prices because NOT NULL was in force two statements earlier, and has a NULL reservation because the column is new. That is branch one, true for every row. - Every statement is re-runnable.
add column if not existsskips;comment on columnis unconditional and harmless;drop constraint if existsthenaddis the right pattern;alter column ... drop not nullon an already nullable column is a documented no-op rather than an error; and all five inserts name a conflict target that is a real primary key (model_aliases_pkey,provider_routes_pkey,provider_capabilities_pkey,alias_route_policies_pkey, and the composite(group_name, alias_id)). Nothing aborts on a second application. The only re-run caveat is the collision case above, which is about a foreign row, not a failure. NOT VALIDis not warranted. Single digit rows: the validating scan is trivial, and splitting it into an add plus a later validate would add a migration and a second lock acquisition to save nothing. Recommending it here would be reflex, not analysis.- Ordering against the other same-day migrations is safe both ways. If theirs applies first, their rows are fixed with non NULL prices and no reservation, which is branch one, so this ADD CONSTRAINT validates them. If theirs applies second, an insert that omits the price columns now fails the CHECK loudly instead of the old NOT NULL, which is the same fail closed answer. One forward hazard worth writing into the header: a future bulk price correction of the 20260801_01 shape will abort on this row unless it carries
where pricing_mode = 'fixed'. - The Go column lists and scan orders line up exactly. Checked column by column, not by eye.
ListPublicAliases,GetAlias,ListAllAliasesandtenantVisibilityQueryeach select the same 15 alias columns in the same order thatscanModelAliaslists 15 destinations, with the two new columns inserted betweencache_write_price_creditsandcreated_aton both sides, and the trailingv.visiblestill carried by the existingextramechanism.LoadAliasPricingselects seven columns in the same order as its seven destinations. No off by one. - The deploy predicate is correct and does cover the variable price route.
pricing_modeis NOT NULL so the added disjunct is two valued, and a fixed row cannot have NULL prices, so the OR never goes unknown. The route also passes the other filters (price_unit = 'tokens',health_state = 'healthy'). Its blind spot is the CRITICAL finding, which concerns a field this query does not read, not the query itself. - The seeded data is consistent with the schema and the rest of the catalog.
provider = 'openrouter'satisfies both the CHECK and the FK tocustom_providers;price_class,health_state,visibility,lifecycleandpolicy_modeall satisfy their CHECKs;price_unitis set explicitly rather than inherited; the alias gets rows in all four companion tables, one more than the voice migration bothered with;provider_modelmatcheslitellm_params.modelverbatim, so the deploy assertion compares equal, and the doubled prefix matches the sibling OpenRouter rows;litellm_model_namecorrectly avoids the existingroute-openrouter-auto;defaultgroup membership only follows the hive-auto precedent from 20260717_01; and NULL cache prices agree withsupports_cache_readandsupports_cache_writebeing false. - No RLS work needed.
model_aliasesand the routing tables are global reference tables, explicitly excluded from the tenant RLS sweep in 20260529_01. - No indexes needed. Every new read is by primary key, and the two new columns are projected, never filtered.
- Types are right.
bigintfor credits andtextfor the discriminator match the table's existing choices. - One thing to remember for later, not a finding now.
metering.RouteInfostill holds plainint64prices, and itsHasCostBasiswould read anupstream_actualroute as no cost basis. Nothing constructs it outside tests yet, so nothing is broken today, but the adapter wave will need the mode.
…ctually record the audit handle The lint failure was a true positive, not lint noise. tools/lint-no-client-cost-fields.mjs forbids a provider-named JSON struct tag anywhere in a Go struct, and the cost decode envelope carried one. Dropping the field outright rather than allowlisting the file, because the field was not earning its keep: it was captured and never read anywhere, and the generation id already recovers both the provider and the exact model that a provider name alone cannot name. That exposed a real gap behind it. The generation id was also captured and never read, so the requirement that a charge be auditable back to a real model was not actually met, only prepared for. Settlement now returns it and every variable-price settlement logs it, on all three dispatch paths, at operator level rather than into audit_log, which fans out to third-party sinks. Note for anyone editing that comment later: the lint matches raw file text, so a comment that quotes the forbidden tag trips it exactly like the code would. The first fix here failed for that reason.

Four of these were the review catching me shipping a plausible number instead of a refusal, which on a money path is the worst failure shape there is. The hold never decoded. ReservationResult reads estimated_credits; the control plane publishes reserved_credits and always has. Nothing read that field before variable pricing did, so the mismatch was invisible, and the first reader of it got a silent zero. Every fail-closed settlement was therefore charging one credit rather than the hold, which is the free-serve bug wearing a different hat. My own end-to-end test missed it because the mock echoed the key the struct wanted rather than the key production sends; the mock now answers with the real wire shape, as a raw map so it cannot start passing again just because a Go struct gained a field. An oversized cost wrapped instead of refusing. big.Int.Int64 is undefined when the value does not fit and returns the low 64 bits with the sign reinterpreted, so a reported cost of 1e20 produced a negative, hit the one-credit floor, and settled as confirmed. Now checked before conversion, with a per-request ceiling in front of it so the overflow check is the second line of defence rather than the only one. An unbounded numeric literal went straight to big.Rat. json.Number only guarantees JSON number syntax and JSON caps no digits, so the parse cost was the caller's to choose. Capped before parsing, since the parse is the expensive part. Both streaming relays published our cost. Turning on usage accounting is what puts the cost, its breakdown and the chosen model into the frame, and the chat relay forwards every line verbatim by design while the typed relay has a raw-line fallback that bypasses the discard it relies on. One sanitizer now serves both, and an unparseable frame is dropped rather than forwarded, because that is precisely the frame whose contents are unknown. The Responses streaming path never captured the usage frame at all, so a variable-price alias could only ever fail closed there. It has the capture and a test that fails without it. Also: pricing_mode was never populated by either catalog builder, so the wire always said empty string; the metering gate's HasCostBasis would have graded a variable-price request not_billable; an empty frame reported as unparseable rather than absent, collapsing the one distinction this package is built around; the panic on the settlement path is now a loud fail-closed return, because a panic there fires during deferred unwinding and strands the hold; and the migration now runs in one transaction with a lock timeout, converges on re-run for the money columns instead of silently keeping a wrong row, and covers the cache price columns in its shape CHECK. The alias is seeded internal rather than public. Migrations apply before the new binaries under deploy: needs: migrate, and the old binary scans the price columns into non-pointer int64 in list queries, so a NULL-priced public row would have taken /v1/models down for every model during that window. It also cannot bill correctly until the LiteLLM pin moves. Flipping it to public is a one-line follow-up once the pin has landed.
routing_client.go still carried the wording catalog/client.go was already fixed for, so the two contradicted each other on the same fact. There is no future tolerant decoder; encoding/json is already the tolerant one, and a null into a non-pointer numeric field is a documented no-op that returns no error. The mismatch does not surface at dispatch, it surfaces as a route priced at zero, which is the stronger argument for the pointer.

…orted cost (#1043) One line of `deploy/docker/docker-compose.yml`: the LiteLLM image pin moves from `v1.77.7-stable` to `v1.98.0`, pinned by tag and digest together. ## Why On the currently pinned version, LiteLLM reconstructs the usage object when relaying SSE and keeps only the keys it declares, so the provider's reported per-request cost never reaches the gateway on a streaming request. The sync path passes the same field through untouched, which is what makes this easy to miss: anything verified only on the non-streaming path looks correct and then bills wrong for every streamed turn, and every chat turn is streamed. This blocks PR #1012, which bills a router alias at actual upstream cost. It is landing separately and first, because a proxy upgrade in front of every request deserves to be revertible on its own. ## Measured, not read off release notes ### On the live demo box, with real provider keys The strongest evidence available, and it is a genuine before-and-after rather than a single reading. Same probe, same route (`route-deepseek-v4-flash`, the OpenRouter-backed route the box actually has), issued from inside the litellm container so no key crossed a boundary. Only the litellm container was recreated; nothing else on the box was touched. | pin | routes resolved | sync `usage.cost` | streaming `usage.cost` | |---|---|---|---| | `v1.77.7-stable` (current) | 13 | 8.064e-06, present | **missing** | | `v1.98.0` | 13 | 7.896e-06, present | **2.05e-06, present** | All 13 routes resolved to identical models on both images. The box was restored to the repo default immediately afterwards and `chat-hive.scubed.co` answers 200; it is not sitting on an unmerged image. ### In a lab, against a fake OpenRouter returning a known cost Run first, to establish the version boundary without spending real tokens. Fake upstream reporting exactly `0.0123456`: | version | sync | streaming | |---|---|---| | `v1.77.7-stable` | preserved | DESTROYED | | `v1.83.14-stable` (newest tagged stable) | preserved | DESTROYED | | `v1.98.0` | preserved | preserved | The middle row is why this is not "upgrade to the newest stable". The newest tagged stable does not carry the fix. Also established there: `usage: {include: true}` reaches the provider even with `drop_params: true` set, both via config `extra_body` and when a client sends it; and the repo's real `deploy/litellm/config.yaml` boots on `v1.98.0` resolving all nine of its routes to the same models. ## The tradeoff, stated plainly `v1.98.0` is newer than `v1.83.14-stable` but is **not** one of LiteLLM's `-stable` releases. It has had less soak time on the component that fronts every request. That is real and it is taken knowingly. What makes it recoverable: 1. **On-box validation before the default moves.** Done, above: swapped, probed, restored, chat verified. 2. **`LITELLM_IMAGE` is a one-variable revert.** Setting it on the box overrides this default with no PR, no redeploy of anything else, and no code change. That is the same mechanism used to run this experiment. ## Alternatives I checked and rejected - **Recover the cost from a response header instead, avoiding the upgrade.** Cannot work. On a streaming request `v1.83.14` returns `x-litellm-response-cost-original: 0.0`, because headers are written before the stream completes. - **Use `x-litellm-response-cost` on the current pin.** Actively dangerous. It returns LiteLLM's own static price-map guess when it has no price for a model: `0.0105` against a real `0.0123456` in the lab. That is a fabricated number on a money path, and it looks exactly like the right answer. ## Pin format Tag and digest together, matching the convention `docker-compose.enterprise.yml` already uses for `supabase/gotrue`, `postgrest` and `storage-api`. The tag stays readable at review time; the digest is what makes it reproducible if the tag is ever moved. The digest was read back off the image that produced the measurements above, not transcribed. ## Risk Config-compatible: the repo config boots unchanged and resolves every route identically, verified on both the lab config and the box's live config. The blast radius is nonetheless every request through the gateway, which is why this is one line in its own PR rather than a hunk inside a pricing change.

…ve-default and hive-auto (#1099) Owner directive, 2026-08-23: route both `hive-default` and `hive-auto` to OpenRouter free models, and charge 50 percent of what is being charged now. One migration plus one LiteLLM config edit. No Go change on the serving path. ## First, a correction to the premise this task was handed with The brief said `hive-auto` bills at actual upstream cost after PR #1012, and therefore had to be converted back to a fixed price with the "today" figure recovered from ledger rows. That is not what #1012 did. It created a **new** alias, `openrouter-auto`, on a new route `route-openrouter-auto-beta`, in `pricing_mode = 'upstream_actual'`. Its own migration says so out loud: "litellm_model_name is deliberately NOT 'route-openrouter-auto': that name is the retired route id of the pre-existing hive-auto alias, which resolves to a completely different model." `hive-auto` was never touched by it. Both aliases are plain `fixed` rows and have been since the 2026-08-22 restructure, so there is no pricing-mode conversion here and no need to reconstruct a price from ledger magnitudes. The old figures come from the statement that set them. ## Before and after Source for every old rate: `supabase/migrations/20260822_02_catalog_alias_restructure.sql` step 7. | alias | unit | old rate | new rate | source of old rate | |---|---|---|---|---| | hive-default | credits per million **prompt** tokens | 10500 | **5250** | 20260822_02 step 7 | | hive-default | credits per million **completion** tokens | 42000 | **21000** | 20260822_02 step 7 | | hive-default | credits per million cache-read tokens (published, never billed) | 0 | 0 | 20260822_02 step 7 | | hive-default | credits per million cache-write tokens (published, never billed) | 0 | 0 | 20260822_02 step 7 | | hive-auto | credits per million **prompt** tokens | 21000 | **10500** | 20260822_02 step 7 | | hive-auto | credits per million **completion** tokens | 84000 | **42000** | 20260822_02 step 7 | | hive-auto | credits per million cache-read tokens (published, never billed) | 0 | 0 | 20260822_02 step 7 | | hive-auto | credits per million cache-write tokens (published, never billed) | 0 | 0 | 20260822_02 step 7 | Every figure halves with no remainder, so no rounding rule had to be invented and no float can enter. Both aliases stay `pricing_mode = 'fixed'` and `price_unit = 'tokens'`. Why the cache columns are listed at 0 and not omitted: they are the only other price columns on the row, `precedence.go` never reads them, and both were already zeroed by 20260822_02 when the aliases moved to Groq routes declaring no cache support. Half of zero is zero, so they are asserted rather than changed. Naming them is the point: "every unit type the alias bills today" is answered exhaustively rather than by omission. ## Why there is no Go change `apps/edge-api/internal/metering/precedence.go` is the single implementation of the charge arithmetic (D-031). It builds exactly two `UnitCharge` values per request, prompt tokens at `InputPriceCredits` and completion tokens at `OutputPriceCredits`, sums them, divides once by a million and rounds half up. So halving those two columns halves every token charge exactly, for every request shape, with nothing else moving: - **The credit hold does not move**, and should not. For a fixed-price alias `ReservationCredits` returns the flat per-endpoint default (10000 for chat); it only raises a hold above that for an `upstream_actual` alias. The hold is an authorization, released in full at settlement. - **The fail-closed path halves too.** A missing usage block synthesises a token count from response bytes and prices it at the same catalog rate, so it lands at half the old figure rather than at zero or at the old rate. - **Non-token modalities are untouched because they never read these columns.** `/v1/images/*` reserves a hardcoded 5000 credits and `internal/audio` charges flat literals, both alias-independent (D-033, issue #627). See the residuals. - **Which token classes are billed does not change.** Only the rate does. There is a guard for this specifically, because a brief of this shape previously produced a 262x overcharge by widening what was billed. ## The money proof: same request shapes, before and after Produced by calling the production settlement function `inference.CreditsForTokens` directly, once with the old rates and once with the new ones, in the repo's own toolchain container. Not a reimplementation: that is the function both the streaming and the sync settlement paths call. Two figures per shape. **Exact** is quantity times rate, summed, before the single division and round-half-up, which is where "exactly half" is provable. **Settled** is the whole-credit charge the ledger records, and both sides round independently. | alias | request shape | prompt | completion | old exact (credit-millionths) | new exact | exact ratio | old settled | new settled | |---|---|---|---|---|---|---|---|---| | hive-default | typical chat turn | 1200 | 400 | 29400000 | 14700000 | **0.500000** | 29 | 15 | | hive-default | long context read | 32000 | 800 | 369600000 | 184800000 | **0.500000** | 370 | 185 | | hive-default | prompt only | 1500 | 0 | 15750000 | 7875000 | **0.500000** | 16 | 8 | | hive-default | completion only | 0 | 900 | 37800000 | 18900000 | **0.500000** | 38 | 19 | | hive-default | tool-call-only turn | 850 | 40 | 10605000 | 5302500 | **0.500000** | 11 | 5 | | hive-default | fail-closed byte estimate | 72 | 1000 | 42756000 | 21378000 | **0.500000** | 43 | 21 | | hive-default | one token each (floor) | 1 | 1 | 52500 | 26250 | **0.500000** | 1 | 1 | | hive-default | 24 completion tokens (floor boundary) | 0 | 24 | 1008000 | 504000 | **0.500000** | 1 | 1 | | hive-default | negative counts clamped | -5 | -5 | 0 | 0 | n/a | 0 | 0 | | hive-auto | typical chat turn | 1200 | 400 | 58800000 | 29400000 | **0.500000** | 59 | 29 | | hive-auto | long context read | 32000 | 800 | 739200000 | 369600000 | **0.500000** | 739 | 370 | | hive-auto | prompt only | 1500 | 0 | 31500000 | 15750000 | **0.500000** | 32 | 16 | | hive-auto | completion only | 0 | 900 | 75600000 | 37800000 | **0.500000** | 76 | 38 | | hive-auto | tool-call-only turn | 850 | 40 | 21210000 | 10605000 | **0.500000** | 21 | 11 | | hive-auto | fail-closed byte estimate | 72 | 1000 | 85512000 | 42756000 | **0.500000** | 86 | 43 | | hive-auto | one token each (floor) | 1 | 1 | 105000 | 52500 | **0.500000** | 1 | 1 | | hive-auto | 24 completion tokens (floor boundary) | 0 | 24 | 2016000 | 1008000 | **0.500000** | 2 | 1 | | hive-auto | negative counts clamped | -5 | -5 | 0 | 0 | n/a | 0 | 0 | Exactly half on every row, in integer rational arithmetic. Not "roughly half", not a fraction of a percent, not unchanged, and not zero. Stated rather than smoothed over: **the settled whole-credit charge can sit one credit above exactly half**, because the old and new charges each round half up independently from exact rationals in a 2 to 1 ratio (29.4 rounds to 29 while 14.7 rounds to 15). The deviation is bounded at one credit, which is 0.00001 USD at the repo's 100000-credits-per-USD constant. The 1-credit floor in `CreditsForTokens` is the other bounded exception: it is what keeps a sub-credit request off zero, it predates this change, and it is why the two floor rows read 1 and 1. Both are visible in the table rather than hidden behind a "50 percent" claim the integers do not literally satisfy. The replay enforced its own claims: it failed the run if any exact ratio was not exactly one half, if any new charge was zero where the old was positive, or if any new charge exceeded half by more than one credit. Full capture, including the commands: `docs/proof/free-route-aliases-half-price-2026-08-23/README.md`. ## The test that fails on the old rate `apps/control-plane/internal/routing/free_alias_pricing_test.go`, offline, reusing the SQL parser already in that package. Ten guards, all positional: the migration declares its arithmetic in a `-- HALVE| alias | field | old | new` table, the test checks that table is arithmetically half, that its OLD column matches the rates actually in force (pinned here so a later edit to 20260822_02 cannot move the baseline), and then that the value each `UPDATE` **assigns** equals half. A correct comment above a wrong `UPDATE` is caught. Mutation tested rather than asserted to work. Six mutations, six kills, control green: | mutation | result | |---|---| | M1 revert hive-default input to the old 10500 | FAIL `TestFreeAliasPricesAreExactlyHalfTheOldRates` | | M2 hive-default output 21000 becomes hive-auto's 10500 | FAIL `TestFreeAliasPricesAreExactlyHalfTheOldRates` | | M3 route-free-auto loses `supports_batch` and both image flags | FAIL `TestFreeRouteAutoCarriesTheSoleCapabilityFlagsForward` | | M4 provider_model loses the `:free` suffix | FAIL `TestFreeAliasRoutesTargetAFreeOpenRouterModel` | | M5 route-free-default loses `tools_supported` | FAIL `TestFreeRoutesKeepTheCapabilitiesTheirAliasesServeToday` | | M6 the retired Groq routes left enabled | FAIL `TestRetiredGroqRoutesAreDisabledAndRepointed` | M1 is the guard the brief asked for: red on the old rate, green on the new one. The existing `TestCatalogAliasPricesMatchProviderRates` cannot cover these two prices, and that is structural rather than an oversight. It derives every credit figure as `usd_per_million * 1.4 * 100000` (D-032), and its `parseRate` refuses a zero rate outright: "that is a mispricing, not a rate". A free upstream costs zero, so the margin formula yields zero, and zero is refused by `SelectRoute` as unpriceable. **These two prices are owner-set, not cost-derived**, and the halving relation is what replaces the formula as the checkable invariant. ## Routing: which free model, chosen from live data `https://openrouter.ai/api/v1/models`, fetched 2026-08-23: 422 models, 22 priced at zero on both prompt and completion. A literal `openrouter/free` id **does** exist; it is a router, not a model. The capability bar comes from what these aliases serve today. Both current routes declare `tools_supported = true`, which is the column PR #206 routes `tools`, `tool_choice` and `response_format` on, plus `supports_streaming` and `supports_reasoning`. Of the 22 free models, five support all of tools, tool_choice, response_format and structured outputs. Joined to `https://openrouter.ai/api/frontend/v1/all-providers`: | free model | provider | trains on prompts | retention | |---|---|---|---| | dots-studio/dots-3-note-preview:free | AtlasCloud | no | retains, period not published | | z-ai/glm-5.2:free | Decart | no | zero retention | | nvidia/nemotron-3-super-120b-a12b:free | NVIDIA | **YES** | retains | | nvidia/nemotron-nano-9b-v2:free | NVIDIA | **YES** | retains | | liquid/lfm-2.5-2.6b:free | Liquid | **YES** | retains | A false green I shipped and then caught, recorded so the next person does not repeat it: the endpoints API reports NVIDIA's provider as `Nvidia` while the provider directory keys it under displayName `NVIDIA`. Joining on displayName alone misses the record and reports every NVIDIA free endpoint as no-training and zero-retention, the exact opposite of the truth. Join on both fields. Live probes with the project's real key, and this is where the paper ranking fell apart: - **`z-ai/glm-5.2:free`**, the only zero-retention candidate and the strongest model on every published axis: **429 on four of four attempts**, `provider_error_code: upstream_429`, `limit_source: upstream_provider_shared_pool`. That is Decart's shared pool, not our account's limit, and buying credits cannot raise it. Rejected on live evidence rather than on paper. - **`openrouter/free` with no provider preference**: five of five succeeded, but four landed on NVIDIA endpoints and **two of five landed on `nvidia/nemotron-3.5-content-safety:free`, a moderation classifier**, which answered a plain chat prompt with `User Safety: safe` and then with an empty string. Unfit for a chat alias on output quality alone, before the training question. This is also the exact shape issue #689 called a bug. - **`openrouter/free` with `provider: {data_collection: "deny"}`**: five of five, only Cohere and AtlasCloud, tool calls on five of five. The deny filter empirically excludes every NVIDIA endpoint and the classifier. - **`provider: {zdr: true}`**, the stricter form: **404, "No endpoints found matching your data policy (Zero data retention)"**. There is no zero-data-retention free endpoint reachable at all today. - **`dots-studio/dots-3-note-preview:free`**: 200 on a sync completion, on a tools request (a real `tool_calls` with correct arguments and `finish_reason: tool_calls`), on `response_format: {"type":"json_object"}` (valid JSON back) and on a streamed request. `cost: 0` on every response. **Chosen: `dots-studio/dots-3-note-preview:free` for both aliases**, pinned, with `extra_body.provider.data_collection: deny` and `allow_fallbacks: false`. It is the only free model that is simultaneously full parity, live verified working, and served by a provider that does not train on prompts. The `deny` preference is kept even though the model resolves to one provider today: if AtlasCloud's policy changes or a second provider appears, the request fails instead of quietly moving customer prompts to a provider that stores them. ### Capability parity verdict | capability | before (Groq gpt-oss) | after (free model) | verdict | |---|---|---|---| | tools, tool_choice | declared, supported | declared, **live verified** with a real tool call | parity | | response_format, structured outputs | routed on `tools_supported` | supported, **live verified** returning valid JSON | parity | | streaming | declared | declared, **live verified**, 20 chunks | parity | | reasoning / reasoning_effort | declared | declared, model enables reasoning by default | parity | | chat completions, completions, responses | declared | declared | parity | | embeddings | false | false | unchanged | | cache read, cache write | false | false | unchanged, no cache rate published | | batch, image generation, image edit | on route-groq-auto only | carried onto route-free-auto | preserved, see below | | vision (image input) | none reachable | upstream is `text+image->text` | **not declared**, see below | Two notes on that table. `provider_capabilities` has no vision column, so the free model's image-input support is an undeclared property of the upstream rather than a new product claim; the 2026-08-22 note that no customer-reachable vision path exists is now inaccurate at the upstream level and the config comment says so. And the three media flags are a documented status-quo fiction inherited through two migrations: neither gpt-4.1-mini, nor gpt-oss-120b, nor this model generates images. They are carried because `route-groq-auto` is their **sole carrier in the catalog**, `SelectRoute` hard-filters on each flag, and `batchstore` sends `NeedBatch = true` for every batch, so disabling it without handing them on would leave `/v1/batches`, `/v1/images/generations` and `/v1/images/edits` with zero eligible routes **for every alias in the system**. M3 above is the guard. Under-claiming is not a safe default here: both aliases are `pinned` to exactly one route, so `matchesRequestedCapabilities` drops the only candidate, `SelectRoute` returns `ErrRouteNotEligible` and `writeRoutingError` maps it to 422. On a pinned alias an under-claim is a failed request, not a withheld feature. ### Rate limits, and what a user sees at the cap Documented (`https://openrouter.ai/docs/api_reference/limits.md`, whose MDX constants resolve to real numbers): free variants are capped at **20 requests per minute**, and at **50 per day** below 10 dollars of lifetime credit purchases or **1000 per day** at or above it. `GET /api/v1/key` reports `is_free_tier: false` for this account and project memory records a 10 dollar purchase, so 1000 per day is the expected tier. The key endpoint does not expose the purchased total, so that is an expectation, not a measurement; its own `rate_limit` field is documented as deprecated and returns `requests: -1`. Separately and more sharply, the Decart 429 shows a per-provider shared pool can refuse everything regardless of our standing. **What a customer sees at the cap today: a roughly 60 second wait and then a 502 whose message is `context canceled`.** That is issue #1089, filed today and unchanged by this work. `num_retries: 3` with `request_timeout: 45` retries a rate-limited deployment three times, the SDK suites time out at 60 seconds, and the provider's own 429 with its retry hint never leaves the LiteLLM container log. Not fixed here, and the reason is containment rather than appetite. The candidate fix (`router_settings.retry_policy.RateLimitErrorRetries: 0`) belongs in the `litellm_settings` block, which the config sync **preserves verbatim** on a live volume. A file edit there is inert on the box and cannot be verified from a developer machine with no SSH to it. #1089 reaches the same conclusion about itself and asks for a real reproduction. This change does make it materially more likely, since 20 requests per minute is much tighter than Groq's ceiling, so its priority moves from latent to likely. Mitigation that does exist: `hive-small` and `hive-medium` stay on Groq and are now the only customer-reachable Groq chat routes besides the deprecated `hive-fast`. A rate-limited customer has a working alternative, but has to select it; nothing routes them there, because the gateway chat fallbacks were removed deliberately in 20260822_02 and re-adding one is the same inert-on-a-live-volume problem. ### Logging and training terms - **OpenRouter itself** stores no prompts or completions unless the account opts in, and both opt-ins (private input/output logging, and letting OpenRouter use inputs/outputs for a 1 percent discount) are off by default. Request metadata (token counts, latency) is always retained. - **AtlasCloud**, serving the chosen model: `training: false`, `retainsPrompts: true`, no retention period published. - The route carries `provider.data_collection: deny` as a fail-closed guard. - **The contradiction, written down because this product sells data sovereignty:** a strict zero-retention posture is not achievable on any free OpenRouter endpoint today, proved by the `zdr: true` 404. The best available free posture is a provider that does not train but does retain for an unpublished period. The owner directed the move with this on the record. ## Why new route ids rather than repointing the two Groq rows The same reason 20260822_02 gave, and it applies in this direction too. The LiteLLM config sync merges **field by field**: the database owns only `model`, `api_base` and `api_key`, and every other key already on the entry survives so that hand-tuning sticks (`mergeParams`, issue #707). Retiring the route id makes the merge drop the whole stale entry, because a known `route_id` that is no longer active is deleted rather than updated. The rows are **disabled, not deleted**, so the change is reversible and `SelectRoute` filters them out. `price_class` stays `standard`, identical to the routes being replaced. `budget` would arguably describe a free upstream better, but `price_class` feeds `allow_price_class_widening`, and keeping the same value means this repoint cannot change selection behaviour through a second mechanism. The `api_key` follows automatically from `providers.api_key_env` for the row's provider slug, so `openrouter` resolves to `OPENROUTER_API_KEY` without the migration naming a secret. The doubled `openrouter/` prefix on `provider_model` is correct: LiteLLM strips the leading one as its provider selector, exactly as `openrouter/~deepseek/...` and `openrouter/openrouter/auto-beta` already do. The trailing `:free` is load-bearing, not cosmetic: dropping it selects a **paid** endpoint of the same model, so the alias would charge a halved price against a real out-of-pocket cost and nothing else in the tree would notice. M4 is the guard. ## Verification - `go test ./apps/control-plane/... -count=1 -short`: clean, no FAIL, no panic. - `go test ./apps/edge-api/... -count=1 -short`: clean, no FAIL, no panic. - New guards, verbose: 10 of 10 pass; 6 of 6 mutations kill a guard. - `npm run lint:litellm-config`: PASS. `npm run lint:litellm-routing`: PASS. `npm run lint:proof-tokens`: ok, 137 files scanned. - `deploy/litellm/config.yaml` parses and resolves 14 model entries, with both new routes carrying the intended `extra_body`. **Not proved, and it matters:** that the running gateway serves the new route. The config is volume-seeded and the live change arrives through `POST /internal/litellm/sync` reading `provider_routes`. There is no SSH to the demo box from here and CI is the only remote hands, so the on-box confirmation belongs to the deploy run. `deploy-demo-box.yml`'s "Assert model catalog prices agree with the model LiteLLM will call" step is the check that catches a stale volume, and its predicate (`pricing_mode = 'upstream_actual' OR input_price_credits > 0`) covers both of these rows. No ledger row at the new price exists yet either; that needs a served request after the migration applies. **No screenshot**, because this change alters no UI surface. The console catalog table renders whatever price the API returns, and the two figures it will show are the ones proved above. ## Residual questions for the owner Both are stated rather than silently resolved, per the brief. 1. **`hive-auto` now costs exactly twice `hive-default` for the identical model.** Both resolve to the same free upstream, so the surviving 2x gap buys the customer nothing. The directive fixes each alias at 50 percent of **its own** old price, which is what shipped; equalising them is a separate decision. Options: (a) leave as is, honest to the directive, indefensible to a customer who compares them; (b) equalise `hive-auto` to 5250 and 21000, a further reduction that cannot overcharge anyone; (c) give `hive-auto` a distinct larger free model. **Recommendation: (b).** Option (c) is blocked today: every other full-parity free model is served by a provider that trains on prompts, and the one zero-retention candidate returns 429 on every request. 2. **The image path is not halved.** `/v1/images/generations` and `/v1/images/edits` reserve and settle a hardcoded 5000 credits that never reads the alias price, so an image request through `hive-auto` is billed the same as before. It is also not actually servable, since the upstream is a text model and those capability flags have been a documented fiction since 20260414_01. Options: (a) halve the literal to 2500, which halves it for every other alias too and so exceeds this directive's scope; (b) leave it and close the fiction under issue #627; (c) drop the flags, which deletes three endpoints catalog-wide. **Recommendation: (b).** ## Buglog entry ```json {"id":"bug-2026-08-23-openrouter-provider-name-vs-displayname-join","date":"2026-08-23","title":"Joining OpenRouter endpoint provider_name against all-providers displayName silently reports a training provider as zero-retention","error_message":"A capability-and-data-policy scan of OpenRouter's free models reported every NVIDIA free endpoint as training:false, retainsPrompts:false, when NVIDIA's published policy is training:true, retainsPrompts:true","root_cause":"GET /api/v1/models/{slug}/endpoints reports the provider in its `name` form (`Nvidia`) while GET /api/frontend/v1/all-providers keys the record by `displayName` (`NVIDIA`). 18 of 82 providers have name != displayName.

Splitting them is what makes "no price moves here" a structural property of a file rather than a claim in its header. ## Prices for these three do NOT change, and that is the intended outcome | alias | unit | rate before | rate after | note | |---|---|---|---|---| | hive-small | credits per million prompt / completion tokens | 10500 / 42000 | **10500 / 42000** | unchanged | | hive-medium | credits per million prompt / completion tokens | 21000 / 84000 | **21000 / 84000** | unchanged | | hive-fast | credits per million prompt / completion tokens | 10500 / 42000 | **10500 / 42000** | unchanged, deprecated alias | The owner's 50 percent instruction applies to `hive-default` and `hive-auto` only. Serving a same-priced alias from a free upstream widens margin, and that is intended. Stated explicitly so no later reader mistakes it for an oversight, and enforced two ways rather than promised: - `TestGroqFreeRepointTouchesNoPrice` fails if that migration assigns any of `input_price_credits`, `output_price_credits`, either cache column, `pricing_mode` or `price_unit`. The migration does not write `model_aliases` at all, so the guard holds in its strongest form. - The DB-level check reads the prices back after the whole chain applies, and they are byte for byte what they were. `hive-fast`'s cache columns stay at 1 and 4, the stale OpenRouter-era values 20260822_02 examined and deliberately left alone so a deprecated alias would not be repriced on any axis. Not touched here either, for the same reason. ## Audio is out of scope, and the survey behind that `route-groq-stt` (whisper-large-v3) and `route-groq-tts` (Orpheus) are untouched, and `TestGroqFreeRepointLeavesAudioOnGroq` fails if that migration so much as names them in an executable statement. `GROQ_API_KEY` stays required; what Groq no longer serves is chat. "OpenRouter has no audio" would have been an overstatement, so here is the actual picture across all 422 models: - **Text to speech: nothing usable.** Not one model, free or paid, advertises `supported_voices`. The only entries with audio in their output modality are `google/lyria-3-pro-preview` and `google/lyria-3-clip-preview` (free, MUSIC generation, no voice selection) and `openai/gpt-audio` and `openai/gpt-audio-mini` (PAID, speech-to-speech chat). None is an OpenAI-compatible `/v1/audio/speech` endpoint, which is what `internal/audio` speaks. **Orpheus has no replacement at any price.** - **Speech to text: three free models take audio as chat input** (`thinkingmachines/inkling:free`, `thinkingmachines/inkling-small:free`, `nvidia/nemotron-3-nano-omni-30b-a3b-reasoning:free`). They are not a transcription endpoint: they are chat-completions models, while `route-groq-stt` is a LiteLLM `mode: audio_transcription` route that edge-api's audio handler forwards multipart audio to. Using one would be a new integration, not a repoint. All three are also served by providers whose published policy is training on prompts, a poor destination for dictated speech specifically. Reported, not acted on, exactly as the directive asked. Bengali voice dictation (PR #1079) keeps working. ## Capability parity, probed live because the parameter lists differ This one genuinely needed checking rather than asserting. `dots-3-note-preview` lists `tools`, `tool_choice`, `response_format`, `structured_outputs`, `reasoning`, `include_reasoning`, `max_tokens`, `temperature` and `top_p`, and does **not** list `reasoning_effort`, `stop`, `frequency_penalty`, `presence_penalty`, `seed`, `top_k` or `logprobs`. The Groq gpt-oss models it replaces accept several of those. So: does an unlisted parameter fail, or is it ignored? Twelve request shapes, live: | request shape | result | |---|---| | baseline | 200 | | reasoning_effort=low | 200 | | reasoning_effort=high | 200 | | stop | 200 | | frequency_penalty | 200 | | presence_penalty | 200 | | seed | 200 | | top_k | 200 | | logprobs + top_logprobs | 200 | | n=2 | 200 | | response_format json_schema, strict | 200 | | reasoning_effort + provider.require_parameters | 200 | **All twelve returned 200 with a correct answer. There is no request shape that works today and fails after the repoint**, which is the regression this check exists to rule out. The `require_parameters` case is the interesting one: OpenRouter considers `reasoning_effort` satisfied by this endpoint even under strict parameter enforcement. Two behavioural differences that are not failures, recorded so nobody files them as new bugs: - `reasoning_effort` is accepted and never rejected, but does not reliably modulate effort: `low` produced more reasoning tokens than `high` in the same run. Requests keep working; the knob stops being meaningful. - `n=2` returns one choice. That is OpenRouter's existing behaviour for a provider that does not implement `n`, identical on the routes being replaced. Capability FLAGS are carried across per route rather than uniformly. `route-free-small` and `route-free-medium` mirror their Groq originals including `supports_reasoning = true`; `route-free-fast` keeps `supports_reasoning = false`, which is status-quo preservation of an under-claim `route-groq-fast` has carried since its original 20260331_02 seed and that 20260822_02 examined and deliberately left alone. Widening it would be safe, but a routing migration is not where a deprecated alias should quietly gain a feature. None of these three is a sole carrier of a media flag, so disabling them removes no endpoint. `TestRepointedGroqTextRoutesKeepTheirCapabilities` asserts both directions: the flags they must have, and that they claim none of the three media flags that belong on `route-free-auto`. ## Concentration risk, stated rather than buried **After this change every customer-reachable chat alias except the two paid DeepSeek ones resolves to ONE model at ONE provider on ONE free endpoint.** Five aliases: `hive-default`, `hive-auto`, `hive-small`, `hive-medium`, `hive-fast`. There are no gateway fallbacks, by deliberate design (20260822_02 removed them because a fallback answers from a model the alias was not priced against). So the failure mode **moves rather than disappearing**. OpenRouter documents free variants at **20 requests per minute**, and 50 or 1000 per day depending on lifetime credit purchases; that per-minute ceiling is tighter than the Groq daily allowance this was meant to escape. Separately, the Decart 429 recorded in part one shows an upstream provider shared pool can refuse everything regardless of our account standing, and buying credits cannot raise it. It also **removes the mitigation part one could still point at.** An hour ago a rate-limited customer could select `hive-small` and land on a different provider. There is no such alias now. **What a demo user sees at the cap is unchanged: a roughly 60 second wait and then a 502 whose message is `context canceled`, never the provider's own 429 with its retry hint.** That is issue #1089. Not fixed here for the containment reason given in part one: the candidate fix lives in the `litellm_settings` block the config sync preserves verbatim, so a file edit is inert on a live box and cannot be verified from a developer machine with no SSH to it. This change raises that issue's priority from latent to likely. **This does not close issue #1088.** That is CI consuming the live demo's provider allowance, a different cause with a different owner, and there is deliberately no `Fixes #1088` line anywhere in this PR. ## Part two verification: the full migration chain on a real Postgres Not a file-parsing claim this time. A throwaway `pgvector/pgvector:pg17` container on its own port, seeded with `.github/ci/test-db-bootstrap.sql` and then every file in `supabase/migrations/` in order, exactly as `.github/workflows/ci.yml` does it. Container removed afterwards. `all migrations applied`, no error. Read back from that database: ``` alias_id | in_credits | out_credits | route_id | provider | provider_model --------------+------------+-------------+--------------------+------------+------------------------------------------------- hive-auto | 10500 | 42000 | route-free-auto | openrouter | openrouter/dots-studio/dots-3-note-preview:free hive-default | 5250 | 21000 | route-free-default | openrouter | openrouter/dots-studio/dots-3-note-preview:free hive-fast | 10500 | 42000 | route-free-fast | openrouter | openrouter/dots-studio/dots-3-note-preview:free hive-medium | 21000 | 84000 | route-free-medium | openrouter | openrouter/dots-studio/dots-3-note-preview:free hive-small | 10500 | 42000 | route-free-small | openrouter | openrouter/dots-studio/dots-3-note-preview:free hive-stt | 0 | 4316667 | route-groq-stt | groq | groq/whisper-large-v3 hive-tts | 0 | 3080000 | route-groq-tts | groq | groq/canopylabs/orpheus-v1-english ``` Also confirmed against that database: - **One enabled route per alias.** The violations query returns exactly one row, `hive-embedding-default` with 3, which is the pre-existing exception the integration suite already records in `pendingMultiRouteAliases`. - **The three batch and image flags have a healthy carrier**, `route-free-auto`. `supports_stt` and `supports_tts` are still on the two healthy Groq audio routes. So `/v1/batches`, `/v1/images/generations`, `/v1/images/edits` and both voice endpoints still find an eligible route. - **`policy_mode` moved on no alias.** `hive-fast` is still `latency`, `hive-small` and `hive-medium` still `pinned`, `hive-default` still `stability`, `hive-auto` still `weighted`. Only the route name inside `fallback_order` changed. - **Idempotent.** Both new migrations re-applied to the same database a second time, both clean, prices identical afterwards. - **Integration suite green** against that database: `internal/routing`, `internal/catalog` and `internal/litellmconfig` all `ok` with `-tags integration`. Running the whole `./apps/control-plane/...` integration suite at once also produced failures in `auditworker`, `marketplace` and `tenants`. Those are package-parallelism collisions on one shared database, not this change: each passes on its own against the same database, and none of them reads any of the four tables this branch touches. ## Two test-file notes a reviewer should see rather than discover - `TestHiveFastIsPinnedToGroqAtCorrectedPrice` is **renamed** to `TestHiveFastIsPinnedToOneRouteAtItsUnchangedPrice` and its provider and provider_model expectations updated, because the route legitimately moved. Its two price assertions (10500 and 42000) are unchanged and are now the DB-level guard that this repoint did not quietly reprice three aliases. Its comment records that these figures are no longer derivable from the upstream's cost, which is zero, and must not be "corrected" to match it. - `TestSelectRouteHiveFastResolvesToGroqAtGroqPrice` in `service_test.go` keeps a name that no longer describes the catalog. It is a stub-driven test of the `SelectRoute` algorithm with synthetic route fixtures; it reads neither the database nor any migration, so it is still a valid algorithm test. Left alone rather than renamed in an unrelated file. Push back if you would rather it were renamed. ## Residual question three, added by part two **There is now no chat alias on a second provider.** With every free-model alias behind one 20-requests-per-minute endpoint and no fallbacks, a single upstream 429 takes the whole chat surface down for that minute. Options: (a) leave it, which is what the directive literally asks for; (b) keep one Groq chat route as a deliberate escape hatch, cheapest candidate being the deprecated `hive-fast`, which costs almost nothing in Groq allowance and preserves a working alias to switch to; (c) fix #1089 first so at least the failure is a fast, correct 429 a client library can back off from. **Recommendation: (c) then (b).** Not done here because #1089's fix is not containable from this environment, per the reasoning above.

Adds the customer-facing alias
openrouter-auto("Openrouter Auto (Task Aware)") routed to OpenRouteropenrouter/auto-beta, and bills it at the ACTUAL per-request upstream cost rather than a fixed catalog price. The owner chose actual cost explicitly when the alternative offered was a fixed ceiling price.auto-betais a router. It picks a different upstream model per request, so OpenRouter's models endpoint reportsprompt: -1, completion: -1for it. Ourmodel_aliasestable carries one fixed input/output price pair per alias and both the credit hold and the settled charge derive from it, so any single number written into those columns is wrong on nearly every request.This alias does not work in chat until the LiteLLM pin moves
Stated up front because it changes how this PR should be read.
Measured, not inferred: on the pinned
v1.77.7-stable, the STREAMING terminal usage chunk carries no cost at all. LiteLLM reconstructs the usage object from its own schema and drops unknown keys. Chat through Open WebUI streams, so on today's pin every streamed request against this alias takes the fail-closed path and is charged the hold.The pin bump to
v1.98.0lands as its own small, independently revertible PR with live on-box evidence. Merge order: the deploy agent'sdeploy/docker/work, then the pin bump, then this.What was PROVED versus INFERRED
Separated deliberately so a later reader can tell which claims were measured.
PROVED by standing the real LiteLLM images up against a fake OpenRouter returning a known cost of
0.0123456, and observing both directions:usage.costusage.costgen-idv1.77.7-stable(current pin)v1.83.14-stable(newest tagged stable)v1.98.0(immutable tag, not a-stablerelease)Also proved:
usage: {include: true}reaches the provider even withdrop_params: trueset, both when injected via configextra_bodyand when sent by a client. The repo's realdeploy/litellm/config.yamlboots onv1.98.0and resolves all 9 routes to the same models. LiteLLM strips the leadingopenrouter/as its provider selector, which is why both the config andprovider_modelcarry the doubled prefix.INFERRED, and still needing real providers to confirm:
openrouter/auto-betabehaves in production the way the fake modelled it, in particular that it returns acoston every successful generation.provider.max_pricegenuinely bounds the rate in practice. This comes from OpenRouter's auto-router documentation, which states the ceiling still applies to the router and is enforced after it resolves a model, failing the request rather than routing to a pricier endpoint. Not measured by me.The proxy-cost trap, and why the warning is written as a rule
x-litellm-response-costlooks authoritative and is not. Onv1.77.7-stableit returned0.0105against a real0.0123456: LiteLLM's own static price-map guess ($3/$15 per million) for a router model it cannot price.Those numbers are version-specific. By
v1.83.14that header returns the provider figure on the sync path. Stating the trap as permanent would read as wrong to anyone checking on a newer version, and a warning that reads as wrong gets ignored along with everything near it. The durable rule, which is what is written intoupstream_cost.gowhere someone would reach for it:A third instance of the same family: on a streaming request
v1.83.14returnsx-litellm-response-cost-original: 0.0. A confident zero is worse than an absent value, because an absent value can be caught and a zero bills nothing. That is exactly the shape that served this gateway free for three days in July, and it is why the parser here reports "zero" and "absent" as two different errors.Invariants, and where each is proved
Every test below was verified to FAIL when the behaviour it guards is broken. That is not a claim: 13 mutations were applied to the implementation and all 13 killed their test. Results are in the review comments.
1. A request must NEVER settle at zero because the cost lookup failed, returned null, or was not attempted.
UpstreamActualSettlementreturns the full hold, flagged unconfirmed, for every failure shape. The only path that charges zero is the one where nothing was produced at all.TestFreeServeGuardNeverSettlesAtZerocovers the three cases as three separate cases: the lookup returns null, the lookup errors on an unreadable body, and the lookup never happened because the stream ended before the usage frame arrived. That third one is what a timeout looks like here: the cost is carried in band, so there is no separate call to time out, and an aborted stream simply leaves no bytes. Testing it as "no bytes" is the honest mapping rather than inventing a network timeout. Mutation M1 (return 0 instead of the hold) kills it.2. A request must never settle below what the upstream charged plus margin.
CreditsForUpstreamCostis cost x 7/5 x 100000, andTestCreditsForUpstreamCostMagnitudeasserts exact figures against a known cost, never "greater than zero", because a non-zero assertion is satisfied by the 1-credit floor. Mutations M2 (drop the margin) and M3 (truncate instead of rounding half up) both kill it.3. The reservation must never under-reserve.
The hold comes from the catalog row (200000) rather than the flat endpoint default (10000), on all four dispatch paths including the Open WebUI chat path, with the endpoint default as a floor so it can only ever raise a hold.
enforcePolicyunderPolicyModeStrictthen refuses when the hold exceeds available credits.TestReservationCreditsCannotUnderReserveand the end-to-end hold assertion cover it; mutations M4 and W2 kill them.Stated honestly rather than papered over: a CONFIRMED settlement bills in full past the hold by existing deliberate design (
finalizeLocked), so a request costing more than the hold can still take a balance negative. That is true of every alias today and is not introduced here. What is new is thatprovider.max_pricebounds the rate, so the overshoot is finite rather than unbounded.4. Settlement is idempotent and the ledger stays append only.
Unchanged. Everything still routes through
finalizeLocked, which already guarantees this with a terminal-status guard, a per-account lock and ledger idempotency keys. This PR adds no new settlement path and no new ledger write.5. All arithmetic uses math/big, never float64.
ParseUpstreamCostreads the cost asjson.Numberand hands the literal tobig.Rat, so no binary float touches a money figure.TestParseUpstreamCostReadsCostExactlyAndCapturesAuditHandlesuses a decimal whose float64 round-trip does not compare equal; mutation M6 (parse viaFloat64()) kills it.6. Provider-blind errors, and the chosen model never reaches the customer.
The tension the brief named is handled on both sides. Internally: the upstream generation id (
gen-...) is recorded as the audit handle, which is what lets anyone recover the exact model OpenRouter chose. Externally: the cost is parsed out of the raw bytes into a private struct and never added toUsageResponse, because thenormalize*functions re-marshal that struct straight to the customer.TestVariablePriceStreaming_LeaksNeitherCostNorChosenModelToTheClientasserts the client body contains the completion text but none of the chosen model, the provider, the cost value, or the cost fields. Mutation W3 (remove the alias overwrite) kills it.Per the owner's decision, the alias NAME deliberately identifies the provider, so no machinery hides the string "openrouter" there. Error messages remain provider-blind.
Schema
Prices go NULL rather than 0 because 0 is already meaningful:
routing.Servicerefuses an alias whose prices are both zero, andRouteInfo.HasCostBasisreads the same condition. The Go readers scan these columns into non-pointerint64, so a NULL is a hard pgx scan error and any reader not taught about variable pricing fails loudly and closed rather than charging zero. A CHECK bindspricing_mode, the prices and the hold together so the database itself refuses an inconsistent row.One correction to a claim I made earlier and want on the record: changing
CatalogPricingto pointers does NOT make the compiler enumerate every reader. It enumerated the readers inside control-plane, but edge-api has its own parallel structs decoded from JSON across an HTTP boundary, where a mismatch surfaces as a runtime decode failure instead. Those were found and updated by hand.apps/edge-api/internal/catalog/client.gomattered most: it backs the/v1/modelssnapshot, so one nulled alias decoding into a plainint64would have taken down model listing for every model.Two places a nulled price would have gone unnoticed
input_price_credits > 0.NULL > 0is NULL, not true, so this route would have dropped out of the guard silently while the check went on reporting green. It needs that assertion more than a fixed-price route does, not less. The predicate now names the mode.apps/web-console/lib/control-plane/client.tscoerced a missing price to 0 with?? 0, which rendered a variable-price alias as free in the admin catalog. It now carries null through and the table shows "Variable".Tension with D-032
D-032 says one model, one price, at the alias level, and that simplicity wins.
openrouter-autois deliberately not one model. This does not revoke D-032: it adds one explicitly discriminated exception, and the discriminator is what keeps every existing fixed-price alias on exactly the path D-032 describes. Keying settlement on the alias's pricing mode rather than on the provider also means a second variable-cost upstream arrives later as a catalog row rather than a code change.Known dependency
deploy/docker/docker-compose.ymlseedsdeploy/litellm/config.yamlinto a named volume onlyif [ ! -f /etc/litellm/config.yaml ], so the route added here is inert on a box that already has the volume. That defect is owned by the agent working ondeploy/docker/and is referenced here so the dependency is visible.Verification
go buildandgo vetclean across control-plane and edge-api.go test ./apps/edge-api/... ./apps/control-plane/... -count=1 -short.npm run buildgreen for web-console.chat-coverage-lib.test.tsandcontrol-plane-host.test.tsresolveREPO_ROOToutside/app, which the web-console image does not contain, so they ENOENT in the container regardless of this diff. Neither touches pricing.What changed after review
The adversarial review found four defects that were shipping a plausible number instead of a refusal, plus a leak. All are fixed and each has its own resolved thread; the short version:
ReservationResultreadestimated_credits; the control plane publishesreserved_credits. So every fail-closed settlement charged one credit rather than the hold, which is the free-serve bug reintroduced. My own end-to-end test missed it because the mock echoed the key the struct wanted rather than the key production sends.big.Int.Int64()is undefined when the value does not fit; a reported cost of 1e20 became a negative, hit the one-credit floor, and settled confirmed.big.Rat, making parse cost the caller's to choose.Plus:
pricing_modewas never populated by either catalog builder; the metering gate would have graded a variable-price request not_billable; an empty frame reported as unparseable rather than absent; the settlement-path panic is now a fail-closed return, because a panic there fires during deferred unwinding and strands the hold; and the migration now runs in one transaction with a lock timeout, converges on re-run for the money columns, and covers the cache price columns in its shape CHECK.Correction to two claims this PR made earlier
Both were wrong in the dangerous direction and are worth recording rather than quietly editing:
Merge order
internaltopublic.Visual proof
NOT captured, and the reason changed during review.
This PR no longer touches a user-visible surface. The alias is seeded
internal, notpublic, so it does not appear in the model picker or in/v1/modelsat all. That was done to close a deploy-ordering hazard (migrations apply before the new binaries, and the old binary would fail its list-query scan on a NULL-priced public row, taking/v1/modelsdown for every model), and it doubles as the gate keeping the alias unreachable until the pin bump lands.So the picker capture belongs to the follow-up PR that flips it to
public, and that is where it should be demanded. What that capture must show, per rule 8 and the bar set by #1007: the alias in the picker, the model answering live, and the turn recorded inusage_eventswith a charge derived from the reported cost rather than from the hold.What does exist today, in place of a screenshot, is live evidence from the demo box that the mechanism this PR depends on works there: with the pin at
v1.98.0, a real streamed completion on the box's OpenRouter route returnedusage.costof2.05e-06, where the current pin returns nothing. That is recorded in #1043 with the before-and-after. It is not a substitute for the picker capture and is not offered as one.Buglog entry
