Closes #6053. Absorbs #6162 (GLM-5.3 reasoning_effort clamp — folded in with its changelog entry and extended to the shared OpenAI-dialect normalizer, so it covers the Responses path and custom zai-style mounts too).

Summary

Adds three built-in providers — Alibaba Cloud Model Studio (Qwen / DashScope / Bailian), Kimi (Moonshot AI), and Zhipu AI (GLM / Z.AI) — each with a default OpenAI-compatible mount and an optional Anthropic-compatible mount, following the pattern established by the DeepSeek provider. Fulfills #5954 (qwen).

Today these platforms are reached via custom providers, which silently drops vendor parameters (#5764) and can't cleanly target subscription-plan endpoints. Each vendor also ships subscription plans (Alibaba Token Plan, Kimi Code, GLM Coding Plan) whose Anthropic-compatible mounts exist specifically for Claude Code / Codex-style tools — the per-key use_anthropic_endpoints toggle lets those tools target the gateway with zero SDK changes.

Decisions (responds to #6053)

Question Decision
Provider IDs alibaba / kimi / zhipu — vendor names, grouping each vendor's multiple surfaces (legacy/workspace/Token-Plan hosts for alibaba; Open Platform vs Kimi Code for kimi; General API vs Coding Plan for zhipu). Open to maintainer preference (dashscope/qwen, moonshot, zai/glm).
Dual-protocol approach Extend the existing DeepSeek use_anthropic_endpoints pattern to all three.
PR shape Single PR (this one). Happy to split per-provider if reviewers prefer.
Subscription-plan ToS Plan endpoints stay opt-in via user-supplied network_config.base_url; provider defaults remain the pay-as-you-go OpenAI-compatible hosts. Docs carry a ToS warning.

Implementation (mirrors DeepSeek)

  • Per-key (and per-alias) use_anthropic_endpoints toggle → routes Chat + Responses through the Anthropic Messages endpoint via the shared Anthropic converters.
  • Per-provider deriveAnthropicBaseURL maps each known OpenAI host shape (legacy / workspace / Token-Plan / Coding / CN) to its Anthropic counterpart.
  • BifrostContextKeyPassthroughExtraParams enabled on every generation method so vendor extras reach the upstream (resolves [Bug]: Unknown request fields are silently dropped for custom OpenAI-compatible providers, making upstream behavior controls (e.g. DashScope's enable_thinking) unreachable #5764 for these providers).
  • Per-vendor reasoning_effort shaping: forwarded only for models that accept it (qwen3.8-max, kimi-k3, glm-5.2) and stripped elsewhere to avoid vendor 400s; max preserved on kimi-k3. Since opening, live dogfooding corrected the qwen3.8-max ladder and added per-model-family clamping on the Anthropic mounts — see "Post-approval dogfood fixes" below. GLM-5.3+ is clamped to its narrowed enum (max/high/low; xhigh→max, medium→high, none/minimal→low) on every OpenAI-dialect mount via the shared normalizer.
  • alibaba uses native /responses + /embeddings (text-embedding-v4); kimi and zhipu Responses fall back to Chat (DeepSeek pattern — no upstream /responses endpoint exists). kimi/zhipu Responses/ResponsesStream route through the Anthropic mount when the toggle is on, chat fallback otherwise.
  • Auth: alibaba uses x-api-key on the Anthropic mount (Bearer on OpenAI mount); kimi and zhipu use Bearer on both.

Testing

  • Unit: 20 deriveAnthropicBaseURL tests + 33 shaping tests — all green. go vet clean, whole workspace compiles, gofmt clean.
  • Harness (make test-core): PROVIDER=alibaba65/65; PROVIDER=zhipu55/55 (serial; kimi harness skipped — targets Open Platform model IDs incompatible with the Coding Plan key used).
  • Live dogfood on both mounts across all three: 20-check smoke suite (chat / stream / tools / embeddings / responses / extra-params / reasoning-effort / list-models), incl. direct POST /anthropic/v1/messages per provider. Transcript summary in the issue thread on request.

Known limitations (documented in the provider docs, not blockers)

  • DashScope /responses cannot ingest tool results — its agent backend rewrites function_call_output to role:"tool" and rejects it. Multi-step tool calling works on Chat Completions; the alibaba harness disables the dual-API tool-continuation scenarios for this reason.
  • qwen3.6-flash /responses 400s on reasoning_effort: high+ (vendor maps those efforts to an out-of-range thinking budget for this model); the harness uses qwen3.7-plus. none/minimal/low/medium work.
  • GLM streams reasoning token-by-token, so a single response can produce hundreds of SSE chunks and tool calls arrive only after the full reasoning trace — hence the raised llmtests stream-chunk caps (500→2500 fatal, 100→1500 tool-detection window).
  • Anthropic mount for zhipu is Coding-Plan-only; enabling the toggle without a Coding Plan base_url derives no valid mount (documented).

Reviewer notes

  • The DeepSeek provider is the established precedent — diffing core/providers/{alibaba,kimi,zhipu}/ against core/providers/deepseek/ is the fastest review path; structural differences are limited to auth headers (alibaba x-api-key), the per-host deriveAnthropicBaseURL tables, and alibaba's native Responses + Embeddings.
  • The llmtests cap raises are the only change to shared test infra; they only loosen upper bounds and cannot turn existing passes into fails.
  • core/go.sum gains one entry (github.com/buger/jsonparser) that the alibaba test build was missing.

Checklist

  • Provider packages follow the DeepSeek dual-protocol pattern

Post-approval dogfood fixes (live-verified 2026-08-21..23)

Dogfooded qwen3.8-max (and hosted GLM) through a local gateway against the Model Studio Token Plan host. Three correction commits on top of the original branch:

  1. qwen3.8-max effort ladder (84734b077): the vendor's OpenAI-compatible enum tops out at xhigh (none/minimal/low/medium/high/xhighmax 400'd with exactly that enum error, so the "vendor auto-maps max→xhigh" assumption was wrong). qwen3.8-max moved from acceptsMaxEffort to acceptsXHighEffort: xhigh forwards verbatim, max clamps to xhigh via the shared normalizer (chat + responses paths). Pinned by folder 57 in the provider harness.
  2. Anthropic-mount hardening (84734b077): the mount proxies Messages to chat-completions internally (nested errors carry chatcmpl-* ids) and 400s out-of-enum output_config.effort instead of mapping it; it also rejects output_config.effort + thinking.budget_tokens set together, and engages thinking on its own from the effort value — so when an effort is set Bifrost sends the effort alone without a synthesized thinking field. deriveAnthropicBaseURL (all three vendors) made idempotent — a base_url already pointing at the mount no longer doubles the /apps/anthropic suffix into a 404.
  3. Model-gated mount clamp (76cfbbfd1): the first clamp was blanket maxxhigh; per Model Studio's model-page docs each family has its own ladder, so clampAlibabaMountEffortForModel now applies: qwen3.8-max keeps maxxhigh; glm-5.3+ takes max/high/low (xhighmax, mediumhigh, minimal/nonelow); glm-5.2/5.1/5 and non-dated deepseek-v4-pro/flash take high/max (xhighmax, low/mediumhigh); dated snapshots deepseek-v4-pro-0813/deepseek-v4-flash-0731 take max/high/low (xhigh/mediumhigh). Zhipu and Kimi mount behavior unchanged.

Docs provenance correction (in 76cfbbfd1): the mount's own API page documents no effort field — output_config.effort on the Anthropic mount is an empirical passthrough (live-verified) to the OpenAI-dialect backend, whose per-model reasoning_effort ladder is documented on the Model Studio model page. Comments, alibaba.mdx, and the changelog now state this instead of citing the mount page for the matrix.

OpenAI-dialect-only params: clear_thinking / enable_thinking / thinking_budget are documented only on the Model Studio model page (OpenAI dialect). A live test showed the Anthropic mount silently ignores unknown top-level fields ("clear_thinking":"garbage" returned 200 unvalidated, while the mount 400s bad output_config.effort — which it does translate). So the mount neither validates nor honors these knobs, and they are intentionally not forwarded there; on the mount, thinking clearing is structural (stop replaying thinking blocks). These knobs work on the default OpenAI-compatible endpoints under extra_params.

Harness note: folder 57 pins the OpenAI-mount clamp. The Anthropic-mount behavior has no harness case — the collection has no alibaba partition, and use_anthropic_endpoints is per-key gateway config a Postman case cannot set; it is pinned by the Go tests in core/providers/anthropic/providereffort_test.go.

Merge Risk: 🔵 Low · up to 744a3

The PR adds three providers, dual-protocol routing, and provider-specific reasoning controls. A few bounded issues remain: Zhipu General API credentials can be used with an incompatible Anthropic mode, equivalent GLM inputs can be serialized differently, and Alibaba’s effort documentation is inconsistent. These warrant owner follow-up but do not indicate a release-blocking failure.

Full details: Description check

Explanation

The description is detailed and covers the purpose, implementation, testing, limitations, related issues, affected areas, and checklist. It omits some template-specific fields, such as explicit type, breaking-change, and security selections, but remains mostly complete.

Full details: Linked Issues check

Explanation

The implementation satisfies the main requirements of provider issue [#6053], including dual mounts, routing, authentication, vendor-specific parameters, schemas, UI, tests, and documentation. Issue [#5764] is only addressed for the three new built-in providers; the broader custom OpenAI-compatible provider passthrough problem remains unresolved.

Resolution

Either implement passthrough for generic custom OpenAI-compatible providers, or narrow the issue linkage and description so they do not claim that [#5764] is fully resolved. Document the limited scope if the provider-specific fix is intentional.

Full details: Out of Scope Changes check

Explanation

Most changes support the provider integrations, but the SCIM comments in ui/app/_fallbacks/enterprise/lib/store/apis/scimApi.ts are unrelated to the linked objectives. The Makefile Docker-build note also requires justification because it is not part of provider support.

Validate the Zhipu endpoint mode before saving

The form allows use_anthropic_endpoints for the default Zhipu General API configuration. The backend derives /api/anthropic for that base URL but does not reject the configuration before persistence. A General API key then receives an upstream 401 when the endpoint is used. Disable this option for General API URLs or block saving until a GLM Coding Plan URL is configured.

Thanks for the review @coderabbitai. Triaged the four comments below — one fixed, two skipped with rationale, one deferred.

1. config.schema.jsonuse_anthropic_endpoints descriptions for kimi_key / zhipu_key ✅ fixed
Valid catch. Both said "Routes chat completions requests…" but this PR implements Responses routing for kimi/zhipu too. Updated both to "Routes chat completions and responses requests through Anthropic-compatible endpoints." to match deepseek_key and reflect actual behavior (8/8 descriptions now consistent).

2. llmtests/chat_completion_stream.go + responses_stream.go — make the tool-stream cap fatal 🚫 skipped
The graceful goto at the 1500-chunk bound is intentional, and its semantics differ from the main-stream fatal cap (2500):

  • The main-stream cap is fatal because that path's only job is to stream content — hitting it means something is wrong.
  • The tool-stream path's job is to detect a tool call; once one is seen, subsequent chunks are noise. GLM models stream reasoning token-by-token before emitting the tool call, so a legitimate trace can run 1000+ chunks. Truncating after detection and passing is correct for verbose models.
  • A true runaway (no natural completion) is still caught by the per-request streamCtx 30s timeout → t.Fatal("Timeout…"), and by the main-path fatal cap when the no-tool-call validation fails ("received N chunks but no tool calls").

Making the tool-stream cap fatal would turn legitimate verbose GLM streams red, which is the exact regression the raise was fixing.

3. core/providers/alibaba/alibaba.go — defensively clone NetworkConfig maps 🚫 skipped
The alibaba constructor is structurally identical to the merged NewDeepSeekProvider — same config.CheckAndSetDefaults() call, same networkConfig: config.NetworkConfig storage. CheckAndSetDefaults already deep-copies ExtraHeaders (codebase gotcha #4 in AGENTS.md). Applying the extra clone only to alibaba would diverge from the established provider pattern; if the defensive copy is worth adding, it belongs in CheckAndSetDefaults (shared infra) as a separate change covering all providers.

4. apiKeysFormFragment.tsx — disable the toggle for Zhipu General API URLs ⏳ deferred
Agreed it's a real UX gap, but the current behavior already surfaces a clean upstream error (the derived General-API Anthropic mount 401s), and the docs page calls out that the Anthropic mount is Coding-Plan-only. URL-coupled conditional disabling in the key form couples the shared form to provider-specific URL rules — worth a dedicated follow-up rather than bundling into this provider PR. Happy to open a separate issue/PR for it post-merge.

The schema-description fix is pushed in ab45ab9.

@is911 Verified.

  1. kimi_key and zhipu_key now state that use_anthropic_endpoints routes both chat completions and responses requests. The schema finding is fixed.

  2. I accept the tool-stream rationale. The 1,500-chunk limit ends collection after tool-call detection. Validation still fails when no tool call is detected. Normal streams retain the fatal 2,500-chunk limit. Note that the Responses tool stream uses a 200-second timeout, while the chat tool stream uses a 30-second timeout.

  3. I withdraw the NetworkConfig cloning concern. ProviderConfig.CheckAndSetDefaults() clones both ExtraHeaders and BetaHeaderOverrides before AlibabaProvider retains config.NetworkConfig. A provider-local copy would duplicate shared behavior.

  4. I agree that the Zhipu General API toggle is a valid deferred UX improvement. Please confirm if you want a follow-up issue for this item after merge.

🐇 ✅

Learning: In `core/internal/llmtests/chat_completion_stream.go` and `core/internal/llmtests/responses_stream.go`, the 1,500-chunk limit for tool-call streams intentionally ends collection without failing after enough chunks have been inspected. Tool-stream validation still fails when no tool call or function-call arguments are detected. The normal streaming paths use a separate fatal 2,500-chunk safety limit.

Learning: In Go providers, `schemas.ProviderConfig.CheckAndSetDefaults()` defensively copies `NetworkConfig.ExtraHeaders` and `NetworkConfig.BetaHeaderOverrides`. Provider constructors, including `core/providers/alibaba/alibaba.go` `NewAlibabaProvider`, can retain `config.NetworkConfig` after calling this shared method without adding provider-local copies of these maps.

@akshaydeo @TejasGhatte @Pratham-Mishra04 — friendly nudge for a review pass on this one when you have a window. It's been open for a few days and the DeepSeek-precedent diff makes it a fast review.

Heads-up on one gap I just closed (commit 61cf0e4): the per-vendor reasoning_effort shaping originally hard-pinned glm-5.2, so a future revision like glm-5.5 would have repeated the exact normalization gap this PR set out to fix — max silently downgraded to high on OpenAI-dialect mounts, and reasoning_effort stripped entirely on the zhipu mount. Verified by probe before the fix:

model supportsMaxReasoningEffort isZhipuReasoningEffortModel normalize(max) before after
glm-5.2 max max (unchanged)
glm-5.3 high ⚠️ max
glm-5.5 high ⚠️ max
glm-5.1 / glm-4.x stripped/downgraded unchanged (floor respected)

The fix is a shared isGLM52OrLater version-floor matcher (GLM-5.x where minor ≥ 2, Coding-Plan [1m] aliases included, 5.0/5.1 and GLM-4.x still excluded since they ignore or 400 the field) now used by supportsMaxReasoningEffort, isZhipuReasoningEffortModel, and isAlibabaReasoningEffortModel (alibaba matches the hosted GLM-5 series generally). Covered by TestIsGLM52OrLater + new glm-5.3/glm-5.5 routing cases; full core/providers/openai suite green.

For existing custom/OpenAI-dialect users on current dev, the short-term glm-5.3 entry is up as #6162 (follow-up to #4467) — once this merges, its explicit prefixes are subsumed by the version floor.

Happy to split per-provider or address anything else that's blocking — just say the word.

Addressed both remaining review findings in 7d67d93:

  • Custom-provider gating: DeploymentsTable now receives the base provider type, and provider-specific deployment sections (including the Zhipu Anthropic gating) key off the effective provider — so a custom provider on the zhipu base type gets the correct alias-level behavior. providerName stays the real name for model lookup and display.
  • Edit-flow timing + saveability: the persisted-toggle clear now watches key.use_anthropic_endpoints (so it runs after the async form.reset populates edit values) and clears with shouldDirty: true, making the correction saveable via the enabled Save button. The per-deployment override stays selectable under the General-API restriction — On is blocked, but a previously persisted On can be remediated via Use key setting / Off.

tsc --noEmit (only pre-existing branding route-tree error), oxlint, and oxfmt clean on the touched files.

Forward the Zhipu endpoint restriction.

At Line 382, anthropicEndpointsDisabled is removed from props. At Line 416, it is not passed to UseAnthropicEndpointsToggleSection.

As a result, Zhipu General API deployments can still select On. Those deployments then route to an Anthropic endpoint that rejects their credentials.

-	return <UseAnthropicEndpointsToggleSection providerName="Zhipu AI" {...props} />;

Snyk remediation — commit 83f7188 resolves 10 of the 11 findings from the security/snyk check:

Finding Fix
8 × Go stdlib advisories (net/url, crypto/tls, encoding/xml, encoding/asn1, html/template, net/http, x/net/idna, dnsmessage) go directive bumped 1.26.5 → 1.26.6 in all modules this PR touches (CI uses GOTOOLCHAIN=auto, so the toolchain resolves automatically)
GO-2026-5841 — OOB read in klauspost/compress/s2 1.18.6 → 1.18.7
GO-2026-5158 — otel baggage header unbounded 1.43.0 → 1.44.0

Remaining (unfixable): GO-2026-5932 flags golang.org/x/crypto/openpgp as unmaintained — there is no fixed version (Fixed in: N/A), and nothing in this repo imports the openpgp package (verified by grep across all modules), so it is a module-level advisory only. If the Snyk gate still fails on it, that finding needs a policy/severity call on the Snyk side rather than a code change.

Verified after the bumps: all workspace modules + the two standalone modules (cmd/e2eseed, the token-exchange example) build, and the provider test suites (openai, alibaba, kimi, zhipu) pass. govulncheck -scan module now reports only the openpgp advisory.

⚠️ Unverified finding
Sandbox verification was unavailable.

Align or justify the OpenTelemetry exporter version skew.

go.opentelemetry.io/otel and go.opentelemetry.io/otel/metric now use v1.44.0, but the direct OTLP metric exporters remain at v1.43.0. Both exporter modules have v1.44.0 releases. OpenTelemetry documents compatibility for newer minor API and SDK upgrades, so this is not a confirmed build failure, but the mixed release set can omit exporter fixes and makes the dependency intent unclear. (pkg.go.dev)

Update both exporters to v1.44.0, or document and test why v1.43.0 is required.

Branch rewritten onto current dev (a7944c3) to clear the merge conflicts that had accumulated behind the force-pushed dev.

What changed:

  • The branch previously carried ~90 files of unrelated drift from an older dev head (MCP credstore/token-exchange, e2eseed, branding, bedrock/gemini/xai, SSRF, migration scripts) that dev has since re-landed independently — that drift was the source of both the 38-file conflicts and the Snyk manifest findings. It is gone; the PR is now a single clean commit with only the provider work (40 files).
  • All provider feature content is preserved: dual mounts, per-vendor reasoning shaping, the GLM-5.2+ version floor (future GLM revisions work on day one), the Zhipu Coding-Plan UI gating, NetworkConfig cloning, and the llmtests stream-cap failure semantics. Conflicts against new dev content (xAI end-to-end test, Bedrock VPC-endpoint form fields) were resolved by keeping both sides.
  • No dependency manifests change anymore, so the Snyk gate now passes ("No manifest changes detected"). The repo-wide bumps from the earlier attempt (go 1.26.6, klauspost/compress 1.18.7, otel 1.44.0) address findings that exist on dev itself regardless of this PR — happy to send them as a separate maintenance PR if wanted.
  • Verified locally: workspace + core build, provider/anthropic/schemas test suites, go vet, gofmt, tsc (pre-existing branding route-tree artifact aside), oxlint/oxfmt, config.schema.json + docs.json validity.

Fix or drop the trailing log in B5.

The message says "fallback applied", but it prints only when len(got) != 1. The fallback for this case hoists the mid-conversation system text, which yields two system blocks, so the log never fires for the interesting outcome and fires for unexpected ones. Assert the intended fallback shape, or remove the block; the role:system assertion above already carries the test.

1152-1173: 📐 Maintainability & Code Quality | 🔵 Trivial | ⚡ Quick win

Correct the "lockstep" claim on the duplicated glm5Minor.

This copy anchors with strings.CutPrefix, while core/providers/openai/utils.go anchors with strings.Index and documents the substring choice for multi-segment catalog IDs. The two bodies differ on purpose, because bareModelName here strips every leading segment and bareModelLower there strips only one. The current comment tells a future maintainer to keep the bodies identical, which would change behavior in one package.

Either restate the comment to describe the intentional difference, or extract one shared helper plus one shared model-normalization function so both packages agree by construction.

…mounts

Adds three built-in providers — Alibaba Cloud Model Studio (Qwen/DashScope),
Kimi (Moonshot AI), and Zhipu AI (GLM/Z.AI) — each with a default
OpenAI-compatible mount and an optional Anthropic-compatible mount, following
the DeepSeek dual-protocol precedent:

- per-key (and per-alias) use_anthropic_endpoints routing through the shared
  Anthropic converters, with per-vendor deriveAnthropicBaseURL host tables
- per-vendor reasoning_effort shaping: forwarded only for models that accept
  it (qwen3.8-max, kimi-k3, GLM-5.2+ via a version-floored matcher so future
  GLM revisions work on day one) and stripped elsewhere
- alibaba native /responses + /embeddings; kimi/zhipu Responses fall back to
  Chat; extra params passthrough enabled on all generation methods
- Zhipu 'Use Anthropic Endpoints' gated to GLM Coding Plan base URLs in the
  UI (key-level switch + per-deployment override), since the Anthropic mount
  rejects General API keys
- NetworkConfig maps cloned in the provider constructors to avoid shared
  mutable state with the caller's config
- llmtests harness accounts + raised stream-chunk caps; runaway tool-streams
  now fail the test instead of passing on an earlier tool event
- config schema entries, UI constants/icons, Mintlify docs
…hosts

The /v1 -> /anthropic replacement and the shared Coding base only hold on
Kimi's own hosts (api.kimi.com, api.moonshot.ai, api.moonshot.cn). Custom
or proxied hosts — including ones that happen to end in /v1 or /coding/v1 —
now keep their configured path and get /anthropic appended, so a proxy's
URL shape is never silently rewritten. Table tests cover the custom-base
fallbacks.
url.Parse accepts scheme-less values like //api.kimi.com/v1 and still
populates Host, so the known-host check now also requires a scheme —
scheme-less bases keep the custom-host fallback. Regression test added.
GLM-5.3 narrowed reasoning_effort to exactly max/high/low and rejects
every other value on the General API (low is newly added; medium/minimal/
none/xhigh are gone). GLM-5.2 keeps the full legacy enum with vendor-side
mapping.

- glm5Minor helper + isGLM53OrLater floor (5.2 logic refactored onto the
  shared parser, no behavior change)
- shared OpenAI-dialect normalizer clamps wider tiers onto the nearest
  supported one for GLM-5.3+ on every mount (zhipu, zai-style custom
  providers), mirroring the Coding Plan's own coercion table: xhigh->max,
  medium->high, minimal/none->low; max/high/low pass through
- applyZhipuReasoning keeps the same clamp on the zhipu mount after the
  generic filter runs, and still strips reasoning for GLM-4.x/5.0/5.1
- covers both the chat and responses converters, which share the
  normalizer; zhipu.mdx documents the per-model enums, the forced-thinking
  change (5.3 rejects thinking.type=disabled), and the coercion behavior

Absorbs maximhq#6162.
…+ GLM-5.3 thinking guarantee

Anthropic-protocol requests carrying output_config.effort (opencode /
Claude Code style) had the field silently discarded on the zhipu and
alibaba Anthropic-compatible mounts: every capability gate was keyed on
Anthropic's own model list, so glm-5.3 / qwen3.8-max failed it at the
converter (budget-only branch) and at both strip layers (typed + raw).

Verified against vendor docs and live upstreams (2026-08-16):

- z.ai's mount accepts output_config.effort for GLM-5.2+ and maps
  out-of-scale values server-side; the field coexists with
  thinking{budget_tokens} (ZCode-proven shape). GLM-5.3+ also 400s when
  the thinking field is absent entirely (mount treats absent as
  disabled; "This model always engages in thinking and cannot be
  disabled"), so thinking is now synthesized/rewritten for
  forced-thinking GLM models: disabled -> enabled + minimum budget,
  missing -> enabled + effort-derived budget.
- Model Studio documents output_config.effort for qwen3.8-max
  (xhigh/medium/low), hosted glm-5.2 and deepseek-v4-pro/flash
  (high/max), mapping out-of-enum values server-side.
- Kimi's mount has no documented effort equivalent; the field stays
  stripped (verified tolerated-but-no-op live).

Implementation: new ProviderFeatures.OutputConfigEffort flag +
provider-aware SupportsProviderEffort predicate used by the converters
and both strip layers. Kimi/Anthropic behavior unchanged; Alibaba
qwen3.8-max/deepseek-v4/glm-5.2+ and Zhipu glm-5.2+ now receive the
field verbatim. Docs (provider MDX pages) updated with the verified
parameter surfaces.
… by host

Custom providers (base_provider_type: anthropic) hardcoded
AnthropicRequestBuildConfig.Provider = schemas.Anthropic and passed the
custom provider's own name into the converters, so the provider-aware
output_config.effort and forced-thinking gates never fired for them —
the live "zai-anthropic" mount (api.z.ai) still dropped effort after
the parent commit.

ResolveAnthropicMountProfile maps well-known Anthropic-compatible hosts
to the profile that applies (api.z.ai/open.bigmodel.cn -> Zhipu,
*.aliyuncs.com -> Alibaba, api.moonshot.ai/.cn + api.kimi.com -> Kimi,
else Anthropic). AnthropicProvider now tags both the build config and
the request's Provider (shallow copy, Mistral-style) with the resolved
profile across ChatCompletion/Responses and their streaming variants.
Custom providers pointed at Anthropic itself are untouched.

Also grants the Zhipu profile InterleavedThinking: z.ai accepts the
interleaved-thinking beta header Claude Code sends against its mount,
and the flag only gates header passthrough.
…ide fragments

midConvPlacementOK required the item immediately after a mid-conversation
system message to be role=assistant (or the entry to be last). Extended-
thinking replay ingests each thinking block as a ROLELESS reasoning item
ahead of the assistant's own item, so every turn-2+ request carrying
thinking history failed the check and took the fallback (hoist for
non-Anthropic families) — losing the array position of the system entry
even though the egress would have regrouped those fragments into a legal
[user, system, assistant, ...] shape. Anthropic's own wire carries thinking
and tool_use INSIDE the assistant message, so the placement is legal there.

The clause now scans forward over roleless assistant-side fragments:
reasoning items are skipped; a function_call settles the clause (the
regrouped assistant is emitted directly after the system turn — its tool
results follow it, never precede it); a trailing reasoning-only run
qualifies. function_call_output (the user side of a tool exchange) and any
other roleless shape still fail the clause, preserving the conservative
fallback. Known theoretical false positive, unreachable from opencode-
shaped traffic: hand-crafted [user, function_call_output, system,
function_call] would forward a shape that egresses as [user, system, user,
assistant] — documented in the gate comment.

Roundtrip coverage: B3 (thinking-replay assistant → native forward),
B4 (textless tool_use assistant turn → native forward), B5 (tool-result
user turn → NOT forwarded). Verified live against the z.ai anthropic-
compat mount: turn-2+ requests now egress the system entry at array
position with cache reads preserved.
The OSS fallback for useGetSCIMProvidersQuery returns unknown[] elements,
which forces every consumer into a per-site `as { enabled?: boolean }`
cast — and fails typecheck outright at any un-cast access
(useOnboardingChecklist.ts on dev: TS18046 'provider' is of type
'unknown'). Type the stub's data as { enabled: boolean }[] mirroring the
fields OSS consumers read off the enterprise response.
…ba anthropic-mount constraints

Discovered dogfooding qwen3.8-max through a local gateway against the
Model Studio Token Plan host (evidence from gateway logstore
raw_request/raw_response, 2026-08-21..23):

1. OpenAI-dialect ladder: qwen3.8-max's native enum tops out at xhigh
   (none/minimal/low/medium/high/xhigh; the vendor 400'd "max" until
   ~2026-08-22) — moved from acceptsMaxEffort to acceptsXHighEffort so
   xhigh forwards verbatim and "max" clamps down to xhigh via the shared
   normalizer (covers chat and responses paths).
2. Alibaba's Anthropic mount does NOT server-map out-of-enum effort —
   it proxies to chat-completions internally (nested error ids are
   chatcmpl-*) and 400s output_config.effort=max with the enum error.
   The alibaba mount profile now clamps max→xhigh before forwarding.
3. The mount rejects output_config.effort and thinking.budget_tokens set
   simultaneously ("'reasoning_effort' and 'thinking_budget' cannot be
   set simultaneously") — chat/responses conversions through the mount
   resolve to effort-only when an effort is present; the vendor engages
   thinking itself. Thinking synthesis for forced-thinking GLM models
   (no effort forwarded) is unchanged.
4. deriveAnthropicBaseURL (alibaba/kimi/zhipu) is now idempotent — a
   base_url already ending in the mount suffix no longer doubles the
   path into a 404 "Not support".

Zhipu and Kimi mount behavior pinned byte-identical (z.ai accepts max
natively and the effort+thinking ZCode shape; kimi strips effort).
Harness folder 57 pins the OpenAI-mount clamp; the anthropic-mount
behavior is pinned by Go tests (no alibaba harness partition exists and
use_anthropic_endpoints is per-key gateway config a Postman case cannot
set — omission to be noted in the PR).

Verified live post-fix via the logstore: upstream body carries
output_config:{effort:"xhigh"} with no thinking field on both ingress
paths, both success.
…docs

The previous max→xhigh clamp applied to every model on the alibaba
Anthropic mount, but Model Studio's own docs give each family its own
reasoning_effort ladder: glm-5.2/5.1/5 and non-dated deepseek-v4-pro/flash
accept high/max (xhigh→max, low/medium→high), glm-5.3+ takes max/high/low
(xhigh→max, medium→high, minimal/none→low), the dated snapshots
deepseek-v4-pro-0813/flash-0731 take max/high/low (xhigh/medium→high),
and only qwen3.8-max tops out at xhigh (max→xhigh). clampAlibabaMountEffort
is now clampAlibabaMountEffortForModel with that per-family matrix,
threaded through the typed strip, raw strip, and setEffortOnOutputConfig
call sites; zhipu and kimi mount behavior stays byte-identical.

Also correct the docs provenance: the mount's own API page documents no
effort field at all — output_config.effort is an empirical passthrough
(live-verified 2026-08-23) to the mount's OpenAI-dialect backend, whose
per-model ladder is documented on the Model Studio model page. Comments
(types.go OutputConfigEffort + Alibaba entry, providerSupportsEffortModel),
alibaba.mdx, and the changelog now say that instead of citing the mount
page for the matrix.

Live-verified on the wire after rebuild: glm-5.2 + max forwards max
(200, thinking response), glm-5.2 + xhigh forwards max, qwen3.8-max + max
still clamps to xhigh, glm-5.3 + medium clamps to high.
…alibaba/zhipu hosts

Matches the Kimi gate from a79bf53: alibaba's deriveAnthropicBaseURL
rewrote any base ending in /compatible-mode/v1 or /v1, and zhipu's any
base ending in /coding/paas/v4 or /paas/v4, so an unrelated custom or
proxied base could lose a path segment or be redirected onto a vendor
Anthropic mount. The suffix rewrites now only run on the vendors' own
hosts — *.aliyuncs.com for alibaba (covering dashscope[-intl|-us],
coding[-intl], and the {WorkspaceId}.{region}.maas workspace/token-plan
shapes), exact api.z.ai + open.bigmodel.cn for zhipu; everything else
keeps its configured path and only gets the mount suffix appended.
Lookalike hosts (dashscope-intl.aliyuncs.com.evil.example) and
scheme-less values take the custom-host fallback.

Red-first: the new custom-host, lookalike, and scheme-less cases in both
utils_test.go tables fail against the suffix-only implementation and
pass with the gate.
…, not out-of-enum low

The glm-5.2/5.1/5 + non-dated deepseek-v4 arm of
clampAlibabaMountEffortForModel mapped minimal/none to low, but low is
outside that family's high/max enum (the same reason low itself maps up
to high) — a raw/native Anthropic body with those values would emit a
value the mount rejects with the reasoning_effort enum 400. The typed
path was already correct (MapBifrostEffortToAnthropic pre-maps
minimal→low, which the clamp then lifts to high); the raw path now
agrees. The mildest tiers collapse onto the mildest valid value, same
rule as every other family arm.

Docs and the changelog carried the same contradiction CodeRabbit flagged
(one page said the family accepts only high/max yet documented
minimal/none→low; the Reasoning Parameter section omitted minimal/none
entirely and claimed GLM-5.3 effort is stripped when the forward set's
glm-5 prefix covers it). Both sections, the clamp comment, and the
changelog matrix now state the implemented mapping; GLM-5.3 is listed in
the forward set with kimi-k3 alone stripped.

Red-first: glm-5.2/minimal, glm-5.2/none, and the new deepseek-v4-pro/
minimal case fail against the old arm and pass after; glm-5.3+ and the
dated snapshots keep minimal/none→low (low is in their enum).

Harness note: no case added — the mount clamp is only reachable with a
per-key use_anthropic_endpoints provider config, which the harness's
default alibaba provider does not carry; the in-process roundtrip and
clamp tests pin the converter output directly.
The x-bf-passthrough-extra-params header gates extraction of extra_params
from the HTTP body at ingress (lib/ctx.go sets the context flag the router
checks before the key is lifted out of the body) and is required on either
endpoint mode; the 'by default' wording referred only to the second stage —
the outbound merge the OpenAI-compatible branches enable via the same
context flag, which the Anthropic-compatible branches never set. Both spots
now name the two stages so 'merged by default' can no longer be read as the
header being unnecessary on the OpenAI path.

Docs-only; prose change, no executable surface to test.

@akshaydeo — state-change note rather than a third bump: CodeRabbit's stale changes-requested cleared today (fresh pass is APPROVED), all threads resolved, checks green, no conflicts with dev. The only remaining blocker is one human approval.

You'd have the most context right now having just verified the adjacent Anthropic-mount logic in #6392 — the core/providers/anthropic/* files here are the trickiest slice. One logistics note: the diff touches Makefile (test targets), which is CODEOWNERS'd to @maximhq/bifrost-admin — if code-owner review is enforced that slice needs an admin pass, so feel free to route.
