chore: fix streaming time calculations by roroghost17 · Pull Request #6495 · maximhq/bifrost

roroghost17 · 2026-08-24T17:15:40Z

Summary

Streaming requests were misreporting Bifrost overhead because the total-wall-clock minus upstream calculation included off-CPU relay/scheduler wait between provider chunks — time the request goroutine spends parked, not doing Bifrost work. This inflated the overhead figure and produced a misleading "core = 95% of overhead" breakdown. This PR instruments the actual Bifrost CPU phases during streaming (SSE framing, per-event JSON decode, schema conversion, outbound marshal, client write) and uses the sum of those measured buckets as the overhead for streams, folding the off-CPU remainder back into upstream so latency = upstream + overhead still holds.

Changes

SSE framing attributed to response-parse: defaultSSEDataReader.ReadDataLine now carries a BifrostContext and wraps each call with a deferred timer that subtracts any upstream-latency delta accrued during the socket read, leaving only the CPU cost of scanner splitting, prefix parsing, and the buffer copy. This runs once centrally for every provider using the shared reader.
Per-event decode timed in OpenAI handlers: sonic.UnmarshalString calls in the text-completion, chat-completion, and responses streaming handlers are wrapped with schemas.AddStreamParse so per-chunk JSON decode lands in the Serialization bucket rather than disappearing into unmeasured overhead.
Per-event schema conversion timed: ToBifrostResponsesStreamResponse and postResponseConverter calls are wrapped with schemas.AddStreamConvert so API-translation work lands in the Conversion bucket.
Outbound relay timed in the HTTP transport: Per-chunk sonic.Marshal (transport CPU) and reader.SendEvent (client socket write) are accumulated into streamTransportCPUNs / streamClientWriteNs and stamped onto the root span via bifrostCtx.StampStreamTransport on every exit path.
computeOverheadBreakdown detects streaming: Presence of any stream-phase attribute (AttrBifrostStreamParseMs, AttrBifrostStreamConvertMs, AttrBifrostStreamBackpressureMs) on the root span marks the trace as streaming. For streaming traces, the provider-internal bucket and the scheduling residual are suppressed (both would double-count the off-CPU relay wait). The function now returns (buckets, measuredMs, isStreaming).
Inject uses measuredMs as overhead for streams: When isStreaming is true, overhead is set to the sum of the measured buckets and upstream absorbs the remainder, keeping the latency identity without surfacing the off-CPU wait as Bifrost cost.
core bucket renamed to scheduling: The residual bucket (goroutine-hop latency between phases) is now labelled scheduling to accurately describe what it measures. All tests and UI references updated.
UI overhead breakdown reworked: Categories are reorganised into Serialization, Conversion, Plugins, Middleware, Key selection, Processing, Networking, Client delivery, and Scheduling. OVERHEAD_LABELS, OVERHEAD_BUCKET_CATEGORY, and OVERHEAD_MEMBER_MERGE replace the previous flat OVERHEAD_CATEGORY_META map. key-pool and key.selection are merged into a single "Key selection" member. Plugin display names are title-cased from their kebab IDs with overrides for known acronyms.

Type of change

Affected areas

How to test

# Core/Transports
go test ./core/providers/utils/...
go test ./plugins/logging/...
go test ./transports/...

# UI
cd ui
pnpm i
pnpm build

To validate streaming overhead correctness end-to-end:

Send a streaming chat or responses request through the HTTP transport.
Open the log detail view for that request.
Confirm the overhead breakdown shows response-parse, convertor, stream-client-write buckets and no scheduling residual.
Confirm upstream + overhead ≈ latency and that overhead reflects only Bifrost CPU, not the full wall-clock minus upstream.

For unary requests, confirm the scheduling bucket still appears (renamed from core) and the total still sums to overhead.

Breaking changes

Yes
No

Security considerations

None. Changes are limited to latency instrumentation, span attribution, and UI rendering of overhead buckets. No auth, secrets, PII, or sandboxing paths are affected.

Walkthrough

The change adds per-event streaming instrumentation across providers and SSE handling, measures transport CPU time, revises logging overhead attribution, and updates the log detail UI for overhead categories, batch operations, and Responses items.

Changes

Streaming overhead measurement and display

Layer / File(s)	Summary
Stream parsing and conversion timing `core/providers/utils/sse.go`, `core/providers/utils/sse_test.go`, `core/providers/{anthropic,bedrock,cohere,openai,gemini}/*.go`	SSE readers and provider stream handlers record parsing and conversion durations for stream events. Existing parsing, warning, conversion, and error flows remain unchanged.
Transport stream timing `transports/bifrost-http/handlers/inference.go`	The HTTP inference handler measures chunk serialization and client-write time and records the totals on stream exit paths.
Streaming overhead accounting `plugins/logging/main.go`, `plugins/logging/overhead_breakdown_test.go`	Logging computes measured overhead and streaming status, excludes provider relay time from streaming overhead, and uses `scheduling` for unary residual latency. Tests cover streaming and residual bucket behavior.
Overhead category display `ui/app/workspace/logs/sheets/logDetailView.tsx`	The log detail view groups spans into user-facing categories, merges members, formats labels, and documents scheduling as the residual bucket.

Batch and Responses log details

Layer / File(s)	Summary
Batch operation parsing and display `core/providers/gemini/gemini.go`, `plugins/logging/main.go`, `ui/app/workspace/logs/sheets/logDetailView.tsx`	Batch creation preserves supplied display names. Batch jobs retain identifiers and source log IDs. The UI detects, parses, and displays all batch operations in a dedicated Details tab.
Responses item rendering `ui/app/workspace/logs/sheets/logDetailView.tsx`	Responses items now support refusal text, summarized tool-call metadata, and redacted fallback payloads.

<Note> v2.0.0 is the first stable release on the 2.0 line. This changelog rolls up `2.0.0-prerelease1` (based on [v1.6.3](https://docs.getbifrost.ai/changelogs/v1.6.3)), `2.0.0-prerelease2`, `2.0.0-prerelease3` and the final release window, so it is the complete delta for a deployment upgrading from any v1.6.x release. Fixes that also shipped on the v1.6.x line after v1.6.3 are listed once here. </Note> <Warning> **Breaking changes.** Read the [v2.0.0 migration guide](https://docs.getbifrost.ai/migration-guides/v2.0.0) before upgrading. - **Custom plugin downloads are SSRF-protected** - a plugin `path` pointing at an http(s) URL is rejected if it resolves to a loopback, private, CGNAT, link-local or otherwise non-public address, and every custom plugin path is re-verified on each restart, including ones defined in `config.json`. - **Custom plugin create and update require admin authentication** - `POST /api/plugins` and `PUT /api/plugins/{name}` reject a custom `path` when the caller only got through because dashboard auth is disabled or unconfigured. - **Governance APIs moved under `/api/governance/*`** - `/api/teams`, `/api/users`, `/api/roles`, `/api/audit-logs` and other top-level governance paths moved under one namespace; Team and User lists use `limit`/`offset` pagination. Routing rules and the complexity analyzer moved from `/api/governance/*` to `/api/routing/rules` and `/api/routing/complexity-analyzer-config`; the old paths remain as deprecated aliases. - **`HTTPTransportPreHook` now runs after authentication** - the pipeline is `HTTPTransportPreAuthHook -> auth -> HTTPTransportPreHook -> handler`. Plugins that inject a credential (`x-bf-vk`, `Authorization`, `x-api-key`) must move that work to the new `HTTPTransportPreAuthHook`, and Go plugins implementing `HTTPTransportPlugin` must add the method (`.so` plugins that predate it are skipped for that phase). - **Legacy telemetry attributes removed** - the `gen_ai.*`-namespaced Bifrost-internal span attributes, `gen_ai.usage.prompt_tokens`/`completion_tokens`, the nanosecond `time_to_first_token` attribute and `x-bf-prom-*` request-header Prometheus dimensions are gone from the OTel and Prometheus connectors. Dashboards should read the `bifrost.*` keys and `time_to_first_chunk`. - **Gemini tool preference** - a Gemini API request carrying both function declarations and Google Search without `include_server_side_tool_invocations` now keeps the function declarations and drops Google Search (previously the opposite). Set `include_server_side_tool_invocations: true` to send both on Gemini 3 models. Vertex is unaffected. </Warning> ## ✨ Features - **Batch Accounting** - Provider batch jobs are tracked in a new `batch_jobs` table and settled asynchronously: results are priced per model from catalog batch rates (0.5 default ratio) on the `/results` path, one aggregate cost log is written idempotently with the creating request's identity, a background sweeper with ownership fencing re-drives jobs that timed out, settled usage is charged exactly once to the creating user's budgets and rate limits (including unscoped virtual key budgets on model-less batch-create requests), mixed-model batch rows are repriced during cost recalculation, and the log detail view shows a Batch Details block with per-state request counts and the settled cost (#5291, #5292, #5293, #5294, #5295, #5296, #6109, #6121, #6376, #6410, #6474, #6505) - **Claude-on-Vertex Batches** - Vertex batch jobs route Anthropic models to `publishers/anthropic/...`, build Claude-on-Vertex JSONL instances, round-trip `custom_id`, and preserve `tools`, `toolConfig`, `cachedContent`, `labels` and `display_name` on Gemini/Vertex batch requests (#5368) - **Input / Output Cost Split** - Every log carries `input_cost`, `output_cost` and `additional_cost` (guardrails, semantic cache, MCP) next to the total, across the RDB, ClickHouse, matviews, recalculation and the quota API; speech, transcription and OCR usages carry `BifrostCost`; the log detail view shows the split with per-category detail (#6511) - **Bifrost Overhead Latency** - `upstream_latency` and `overhead_latency` are recorded on every log, aggregated (avg, p90, p95, p99) in the dashboard's new Bifrost Overhead chart and shown in the log detail view; the overhead is decomposed by span self-time into serialization, conversion, plugins, middleware, key selection, queue wait, networking, client delivery and scheduling buckets (including streaming per-chunk parse, conversion and backpressure and the worker hand-off), persisted to `overhead_breakdown` and rendered as a stacked bar in the log detail view; a `bifrost_overhead_latency_microseconds` histogram is exported to Prometheus and OpenTelemetry and `upstream_latency_ms`/`overhead_latency_ms` tags to Maxim, while breakdown spans are kept out of observability connectors (#5533, #5534, #5535, #6345, #6388, #6389, #6433, #6470, #6495) - **Notification Center** - Role-targeted dashboard notifications stored in the database, delivered over WebSocket and surfaced in a topbar tray via `GET/POST /api/notifications` (#6207, #6227, #6324) - **Topbar and Responsive Dashboard** - Persistent topbar with page titles, theme toggle, external links, user menu and version; responsive layouts across all views with truncation and tooltips for long values and icon-only buttons; version-skew detection with an auto-reloading upgrading screen (#6196, #6105, #6126, #6204, #6232, #6330, #6370, #6476, #6485, #6493) - **Video Edits** - `POST /v1/videos/edits` applies prompt-driven edits, upscaling and background removal to an existing video supplied as bytes, a URL or a provider video ID, on OpenAI and Runware (#6270) - **Runware Chat, Catalog and Media Operations** - Chat completions, streaming and Responses via Runware's OpenAI-compatible endpoint, `ListModels` from the curated catalog, image upscale via `/v1/images/edits` (`type=upscale`), image-to-3D and async 3D generation via `/v1/videos` (`type=3d`), provider-reported per-task cost, and a raw `/runware_passthrough` route (#6260, #6372, #6208, #6075) - **JSON Image Edits** - `POST /v1/images/edits` accepts JSON bodies with URL or base64 images and typed extra params in addition to multipart (#6418) - **OpenAI Ultrafast Service Tier** - `service_tier: "ultrafast"` is forwarded only to models that support it and billed at dedicated ultrafast rates, with matching custom pricing override fields (#6396, #6399) - **Service Tier on Logs** - Logs record the tier actually served, including Anthropic's `service_tier` from `message_start` on streams, with a Service Tier column and detail field so repricing uses the served tier (#6233, #6236) - **Pricing Fields** - New per-request flat fee (`cost_per_request`), megapixel-based image tiers (4/8/16/32/64 MP), per-size and joint size+quality image rates for `gpt-image-1`-style models, and `input_cost_per_query` for rerank flow through datasheet sync, the cost engine, custom overrides, the API and the UI override form; upscale output resolution is backfilled from `target`/`factor` on Replicate so tiered rates bill the real output size (#6079, #6082, #6083, #6379, #6380) - **Model Catalog Pricing and Overrides** - Pricing data in the model catalog (thanks [@johnbrett](https://github.com/johnbrett)!), with resolved pricing overrides exposed on `/api/models/details` and on catalog rows, shown in the dashboard (#6055, #6056, #6058) - **Typed Embeddings on Bedrock** - Titan V2 `embeddingTypes` and Cohere `embedding_types` on Converse, the native invoke route and LangChain `BedrockEmbeddings` (#6381) - **Rerank Upgrades** - Structured JSON documents, `return_documents`, `next_token` pagination, caller document IDs preserved in every result, Cohere-shaped errors, cross-provider responses converted back to the caller's wire shape, and `/genai/v1/rank` served cross-provider (#6328, #6301, #6432) - **OpenRouter Speech, Transcription and Embeddings** - TTS and STT through OpenRouter's audio endpoints, and embedding models included in `ListModels` (#5734, #6264) - **Grok on Bedrock Mantle** - `xai.` models route through the `openai/v1` Mantle path (#6022) - **Gemini 3 Thinking Levels** - A per-model `thinkingLevel` support table clamps requested levels to the rungs each model implements; `reasoning_effort: "none"` sets the model's floor level instead of zeroing `thinkingBudget` (#6280) - **Datasheet-Backed Compatibility** - Anthropic, Bedrock, Cohere and Gemini request shaping (adaptive thinking, native effort, disable-reasoning, mid-conversation system turns, computer-use and text-editor tool generations, default max output tokens, tool validation) is resolved from model capabilities instead of hardcoded model-name checks (#6281, #6492) - **Reasoning Effort None** - Models that reason by default but do not support reasoning with tool calls get `reasoning.effort: "none"` when they advertise `supports_none_reasoning_effort`, instead of losing `reasoning` entirely (#6293) - **HTTP Transport Pre-Auth Hook** - New `HTTPTransportPreAuthHook` plugin phase runs before transport authentication so plugins can inject credentials such as `x-bf-vk`; a `virtual-key-from-config` native plugin example ships alongside it (#6375, #6373) - **Plugin Inject Limits** - Per-plugin `semaphore_size` and `inject_timeout` on `PluginConfig` bound observability `Inject` calls so a hung connector releases its slot (#6341) - **Harness Session Autodetection** - Claude Code, Codex CLI and OpenCode session headers populate the session ID when `x-bf-session-id` is absent (#6333) - **Auth and Model Check Skip Paths** - Context keys let trusted internal callers bypass auth resolution, and let evaluate-only requests such as `/inspect` bypass the virtual key provider and model allowlists while budgets and rate limits still apply (#6124, #6479) - **Passthrough Encoding Negotiation** - Forwarded `Accept-Encoding` is filtered to decodable codecs (gzip, deflate, brotli, zstd; gzip and identity for streams) and chained content encodings are decoded (#6360) - **Routing Plugin** - Routing rules and the complexity router live in a dedicated `routing` plugin that runs after governance so rules evaluate on the fully stamped context; endpoints moved to `/api/routing/rules` and `/api/routing/complexity-analyzer-config` with deprecated `/api/governance/*` aliases; complexity routing now reads the text of mixed text+image turns (#6144, #6145, #6146, #6147, #6253) - **Dimension Scope Ceiling** - Grouped log analytics (rankings, histograms, key pairs) are bounded to the customer, team, business unit, user and virtual key ids the caller may see (#6262) - **MCP Per-User OAuth and Token Exchange** - MCP clients can hold per-user OAuth credentials and per-user headers, configurable from `config.json` as well as the UI, with a documented shared vs per-identity token lookup contract, `oauth_config.resource` (RFC 8707), VK/Users filters on the OAuth Grants and MCP Auth Sessions sidebars and one shared create/install client form; `token_exchange` gains `use_idp_credentials` to reuse SSO login app credentials for providers such as Microsoft Entra ID (`client_id` becomes optional) and combines `offline_access` with `<audience>/.default` for Entra OBO; shared-OAuth clients show `needs_reauth` when their token row is invalidated, `Reauthorize` is limited to shared clients, the OAuth flow claim is atomic against concurrent reauth, stored scopes survive a decode failure, and credential caches propagate cancellation and version their entries (#6068, #6069, #6078, #6411, #6428, #6429, #6504) - **MCP Connection Lifecycle and Tool Discovery** - Discovered tools persist and resync uniformly across all client types through a hash-gated core callback, surviving restarts and propagating across a cluster; connections use make-before-break reconnects with ephemeral clients rebuilt across the whole connect+init retry, last-known tool maps preserved, connect attempts bound to entry identity and background reconnects deduped; `needs_session_stickiness` is pinned across `config.json` reconciliation; updating static headers on a sticky client pre-flight verifies the new credential and swaps it onto the live connection, per-call shared-credential clients refresh tools synchronously, and a failed enable parks the client at `Disabled` so it can be retried; the global `tool_sync_interval` hot-reloads and re-times running checkers; state badges render with spaces and the `disconnected` filter bucket is now `unstable` (#6409, #6430, #6431, #6483, #6502) - **Air-Gapped MCP Catalog** - `mcp_library_sync_interval: 0` disables catalog sync and `file://` URLs load the MCP server library from disk (#6195) - **MCP Log Redaction and Plugin Logs** - MCP tool logs carry redaction mappings and plugin logs (#5744, #5746) - **Splunk Connector Configuration** - `config.schema.json`, Helm values and dashboard entries for the Splunk HEC observability connector (#6296, #6091, #6099) - **Helm Broker Clustering** - `bifrost.cluster.type: broker` with broker address, port and TLS settings alongside the existing mesh transport (#6398) - **HTTP/2 Ping Interval in the UI** - Provider network configuration exposes `http2_ping_interval_in_seconds` (#6228) - **Status Code Badges** - Error and passthrough logs show the upstream HTTP status code in the log detail header (#5536) - **Server-Side Tool Calls in Logs** - `web_search_call`, `code_interpreter_call` and similar Responses items render their full payload in the log detail view (#6475) - **Gemini Server-Side Tool Calls** - Gemini `toolCall`/`toolResponse` parts surface as `web_search_call` items with their own call ID and queries, unmapped tool types are preserved on the native round-trip, and each `thoughtSignature` appears exactly once on replay (#6071) - **Bedrock VPC Endpoints** - AWS Bedrock keys can target VPC endpoints (#6064) - **W3C Trace ID Propagation** - Requests carry a W3C trace ID on the context (#5945) - **Durable Background Jobs** - New `sidekiq` background-job table, store methods, and runner with recovery and reaper; cost recalculation migrated to a durable, resumable and cancellable job with polling instead of SSE (#5800, #5801) - **Separate OTEL Metrics Pipeline** - The OTEL collector supports a metrics tab independent of traces, plus separate headers for traces and metrics (#5939, #5940) - **Grouped Logs View** - The logs table groups fallback chains under expandable roots backed by the new `roots_only` filter with child aggregates, and the model catalog persists tab, search and provider in the URL (#5522, #5737, #6059) - **User Agent and App Attribution** - Logs and MCP tool logs record user agent, app, source, decision, app key and device ID, with custom user-agent mapping and dashboard dimension rankings; MCP tool logs observed by the Bifrost Edge agent can be ingested with device, app key, decision and source attribution - **S3 Log Export Metadata** - Additional metadata is written alongside S3 log exports (#6070) - **Matview Maintenance Off Switch** - `matview_refresh_interval` accepts `"off"` to disable logstore matview maintenance entirely (thanks [@jeremym-tanium](https://github.com/jeremym-tanium)!)

(#6302) - **GenAI SSE Heartbeats** - GenAI streams delimit heartbeat comments so Google SDK clients preserve the following event, while older openai-go clients keep the bare heartbeat (thanks [@dani29](https://github.com/dani29)!) (#6252) - **OpenCode max_tokens** - `max_tokens` is preserved for OpenCode-compatible chat endpoints (thanks [@Alex-wangyang](https://github.com/Alex-wangyang)!) (#6458) - **HuggingFace Streaming Usage** - HuggingFace is no longer listed as omitting the `[DONE]` marker, and `stream_options.include_usage` defaults on its chat streaming path, so streamed calls stop reporting zero tokens and zero cost (thanks [@elliottrabac](https://github.com/elliottrabac)!) (#6478) - **Provider Key Name on Update** - A key PUT that omits `name` no longer clears it, and already-exists errors keep their constraint detail (thanks [@cpsc](https://github.com/cpsc)!)

(#5351) - **MCP Tool Sync Interval Corruption** - Toggling an MCP client's enable/disable switch no longer corrupts `tool_sync_interval`; the value is a whole number of minutes, negative values are rejected instead of silently disabling sync, and re-enabling a per-call client restarts its discovery cycle (#6409, #6502) - **MCP Tool Map Staleness** - `SetClientTools` replaces the in-memory tool map instead of merging, so tools removed upstream leave memory once the database has dropped them (#6484) - **SSE Reconnect Identity** - `OnConnectionLost` on SSE MCP clients is gated on connection identity so a stale connection cannot tear down its replacement - **Connector Header Redaction** - `Authorization`, `x-api-key`, Cloudflare Access and AWS ALB OIDC headers are redacted before export to every observability backend (#6371) - **Vertex Mixed Tools** - Vertex AI accepts function declarations and Google Search in the same request without `includeServerSideToolInvocations`, and search localization via `retrievalConfig.latLng` is preserved (#6066) - **Gemini Tool Preference** - When tool combination is disabled, function declarations win over Google Search so the model can still call the caller's tools (#6065) - **Bedrock Stop Reasons** - Bedrock `content_filter` and `guardrail_intervened` stop reasons map to `incomplete` status with a `content_filter` reason - **Encrypted Reasoning on Compaction** - The fail-soft that strips `encrypted_content` before retrying a rejected request also covers `/v1/responses/compact` and count-tokens requests, and recognizes Anthropic's `redacted_thinking` rejection (#6041, #5960) - **DAC-Scoped VK Reads** - `from_memory` virtual key reads are blocked for DAC-scoped callers - **Path Normalization Auth Bypass** - Fixed a path normalization flaw that allowed auth to be bypassed (#5763) - **Minimal Reasoning Effort on GPT-5 Models** - `reasoning_effort: "minimal"` is preserved for GPT-5-family OpenAI models instead of being downgraded to `low` (thanks [@jitokim](https://github.com/jitokim)!) (#6046) - **Gemini Truncated Response Finish Reason** - Truncated Gemini responses report `MAX_TOKENS` instead of `OTHER` (thanks [@AdityaPainuli](https://github.com/AdityaPainuli)!)

(#6332, #6374, #6420, #6147, #6203, #6099, #5938, #6019, #6425, #6448) - **Helm** - Chart releases v2.1.35 and v2.1.36 (#6129, #6249) - **Governance Route Families** - Editions can override governance route families (#5839) ## 🗄️ Database Migrations All migrations below are new relative to v1.6.11. Deployments on an older v1.6.x release should also review the intermediate v1.6.x changelogs. **configstore:** - **add_mcp_client_pending_oauth_config_json_column** - Adds `pending_oauth_config_json` to `config_mcp_clients`. Reversible: drops the added column. - **merge_oauth_token_tables** - Consolidates `oauth_tokens` and `oauth_user_tokens` into `mcp_oauth_tokens`. **Non-reversible**: rollback deliberately leaves `mcp_oauth_tokens` in place, because every OAuth read and write targets it from this migration onward and dropping it would destroy any token created or refreshed since, forcing every holder to re-authorize. - **create_mcp_oauth_flows_table** - Creates `mcp_oauth_flows` to track in-flight OAuth flows. Reversible: drops the new table. - **drop_oauth_config_pkce_columns** - Drops CSRF state, PKCE verifier and `expires_at` from the OAuth config table now that they live on `mcp_oauth_flows`. **Non-reversible**: forward-only, the dropped values were per-flow ephemeral and re-adding empty columns would restore nothing. - **drop_oauth_config_token_id_column** - Drops `token_id`. **Non-reversible**: forward-only, it was a pure FK shortcut now reachable via `(oauth_config_id, auth_mode)`. - **add_mcp_admin_auth_mode_indexes** - Adds admin partial unique indexes on `mcp_oauth_tokens` and `mcp_per_user_header_credentials`. Reversible: drops both indexes. - **add_mcp_client_token_exchange_json_column** - Adds `token_exchange_json` to `config_mcp_clients`. Reversible: drops the added column. - **add_needs_session_stickiness_column** - Adds `needs_session_stickiness` to `config_mcp_clients`. Reversible: drops the added column. - **add_bedrock_endpoints_columns** - Adds Bedrock VPC endpoint columns to the keys table. Reversible: drops the added columns. - **add_cost_per_request_pricing_column** - Adds `cost_per_request` to model pricing. Reversible: drops the added column. - **add_notifications_table** - Creates the `notifications` table for the dashboard notification center. Reversible: drops the table. - **add_batch_jobs_table** - Creates `batch_jobs` with a unique `(provider, batch_id)` identity index, a sweeper scan index and a runner-id index. Reversible: drops the table. - **add_image_megapixel_tier_pricing_columns** - Adds the five `output_cost_per_image_above_{4,8,16,32,64}_megapixels` columns to model pricing. Reversible: drops the added columns. - **add_input_cost_per_query_column** - Adds `input_cost_per_query` to model pricing for rerank. Reversible: drops the added column. - **add_ultrafast_pricing_columns** - Adds the four `*_ultrafast` token rate columns to model pricing. Reversible: drops the added columns. - **add_image_size_quality_pricing_columns** - Adds the 14 per-size and size+quality image output rate columns to model pricing. Reversible: drops the added columns. - **add_batch_jobs_attribution_columns** - Adds `user_id`, `team_id`, `customer_id` and `source_log_id` to `batch_jobs` plus a `user_id` index. Reversible: drops the index and the four columns. **logstore:** - **logs_add_guardrail_debug_column** - Adds `guardrail_debug` to logs. Reversible: drops the added column. - **mcp_tool_logs_add_redaction_mapping_column** - Adds the redaction mapping column to MCP tool logs. **Non-reversible**: rollback is a no-op because dropping the column would permanently destroy reveal data for already-redacted MCP logs. - **logs_add_user_agent_column** - Adds user agent and app columns, their indexes, and a `UserAgentMapping` table. Reversible: drops the indexes and the mapping table. - **mcp_tool_logs_add_user_agent_column** - Adds user agent and app columns plus indexes to MCP tool logs. Reversible: drops both indexes and the `app` column. - **logs_recreate_matviews_with_app_column** - Recreates the log materialized views to include the user agent and app columns. Rollback is a no-op because `ensureMatViews` recreates them on next startup. - **mcp_tool_logs_add_endpoint_columns** - Adds `source`, `decision`, `app_key` and `device_id` to MCP tool logs. Reversible: drops all four columns. - **mcp_tool_logs_add_plugin_logs_column** - Adds `plugin_logs` to MCP tool logs. Reversible: drops the added column. - **logs_add_video_edit_input_column** - Adds `video_edit_input` to logs. Reversible: drops the added column. - **logs_add_upstream_and_overhead_latency_columns** - Adds `upstream_latency` and `overhead_latency` to logs. Reversible: drops both columns. - **logs_add_batch_debug_column** - Adds `batch_debug` to logs. Reversible: drops the added column. - **logs_add_cost_breakdown_columns** - Adds `input_cost`, `output_cost` and `additional_cost` to logs. Reversible: drops the three columns. - **logs_recreate_matviews_with_cost_breakdown** - Marks the hourly matview for rebuild with the cost split columns; `repairMatViewShapes` drops and recreates `mv_logs_hourly` on the next startup. Rollback is a no-op because `ensureMatViews` recreates it on next startup. - **logs_add_overhead_breakdown_column** - Adds `overhead_breakdown` to logs. Reversible: drops the added column. <Warning> **High-throughput deployments: run the logstore migrations during a low-activity window.** Every logstore migration above alters `logs` or `mcp_tool_logs`, the two highest-insert tables in Bifrost, and several also build indexes on them. On a busy instance the index builds hold locks that block concurrent log inserts for the duration of the build, and the matview recreations rebuild against the full table. Schedule the upgrade for a low-traffic period, or expect elevated log-write latency and possible request-path backpressure while the migrations run. </Warning> <Warning> `merge_oauth_token_tables`, `drop_oauth_config_pkce_columns` and `drop_oauth_config_token_id_column` transform or remove existing OAuth state and cannot be rolled back. Take a database backup before upgrading, and do not roll the binary back past this release once the migration has run. </Warning> ## 🐙 Closed GitHub Issues - [#123](#123) - Files API Support - [#2347](#2347) - MCP tool ordering is non-deterministic, breaking prefix-based prompt caching - [#3455](#3455) - Segfault/nil dereference panic in Bedrock provider - [#4318](#4318) - allowed_models persisted as bare "*" string blocks subsequent provider updates - [#4353](#4353) - config.db corruption from masked-key preview in provider_configs JSON column - [#4367](#4367) - Image incompatible with OpenShift arbitrary UIDs - [#4402](#4402) - Vertex provider drops image blocks whose URL uses gs:// scheme - [#4477](#4477) - Passthrough calls using a Virtual Key log as actual key - [#4679](#4679) - Bedrock Responses API does not signal max_output_tokens truncation - [#4689](#4689) - Custom providers cannot set budget - [#4712](#4712) - ElevenLabs sound effects (/v1/sound-generation) - [#4780](#4780) - Anthropic server-side tool_search results are dropped on /v1/responses - [#4834](#4834) - /v1/rerank is not available with custom providers - [#4846](#4846) - Responses stream usage present in response.completed but not persisted in LLM Logs - [#4851](#4851) - Governance rate-limit reset causes high CPU in BumpRateLimitUsage - [#4870](#4870) - Pooled ChannelMessage retains request body, context, and undelivered response while idle - [#4940](#4940) - Show canonical model names instead of Bedrock inference-profile IDs in Model Rankings - [#4963](#4963) - Streaming finish_reason dropped from the accumulated (logged) response - [#5002](#5002) - gpt-4o-transcribe-diarize transcription fails due to string segment IDs - [#5013](#5013) - OpenAI /responses/compact input serialized as a JSON object causing 400 - [#5026](#5026) - [Bug]: Toggling an MCP client's enable/disable switch corrupts its tool_sync_interval (nanoseconds resent as minutes) - [#5027](#5027) - MCP Tool Execution Timeout placeholder shows 0 instead of real global default - [#5036](#5036) - Plugin StreamInterceptionError is flattened on integration routes - [#5037](#5037) - Disabled keys break provider model discovery - [#5051](#5051) - Add Sarvam AI provider (chat + TTS/STT) - [#5061](#5061) - Streaming responses drop citation annotations from the accumulated message - [#5093](#5093) - Streaming /v1/responses drops Anthropic redacted_thinking blocks - [#5097](#5097) - Anthropic rejects replayed tool_use/tool_result ids from non-conforming upstream providers - [#5100](#5100) - additional_tools loses nested tool types on /v1/responses - [#5101](#5101) - Chat-to-Responses tool replay sends role on function_call input items - [#5108](#5108) - Bedrock reasoning_config silently dropped on cross-provider translation - [#5113](#5113) - Gemini/Vertex streaming stops emitting web_search_call items after first grounded request - [#5432](#5432) - Add TTS and STT support for OpenRouter - [#5472](#5472) - [Bug]: Bedrock rejects office/PDF document uploads via OpenAI `type:"file"` - "The PDF specified was not valid" - [#5871](#5871) - [Bug]: AWS Bedrock Mantle streaming is broken - [#5874](#5874) - [Bug]: SSE heartbeat frame aborts streams for openai-go ssestream consumers (< v3.43.0) with "unexpected end of JSON input" - [#5885](#5885) - [Bug]: v1.6.8 omits message_start.message.usage on Bedrock-backed providers, breaking @ai-sdk/anthropic streaming - [#5900](#5900) - [Bug]: Streaming continuation chunks materialize omitted tool-call metadata as null - [#5978](#5978) - [Bug]: Gemini egress reports truncated responses as FinishReason OTHER, IncompleteDetails switch matches a string that never occurs - [#6044](#6044) - [Bug]: normalizeOpenAIReasoningEffort maps 'minimal' to 'low' for ALL OpenAI models, even ones that natively support 'minimal' - [#6240](#6240) - [Bug]: GenAI SSE heartbeat framing causes @google/genai to silently drop the following data event - [#6248](#6248) - [Bug]: OpenRouter embedding models missing from Semantic Cache dropdown - [#6334](#6334) - [Bug]: Gemini/Vertex provider fails on Claude Code assistant prefills and mid-conversation system turns (Gemini 3.6 Flash & 3.7 Flash HTTP 400) - [#6342](#6342) - [Bug]: Anthropic ingress with bedrock/ prefix restructures replayed thinking blocks, wedging multi-turn tool use on claude-opus-4-8 - [#6416](#6416) - [Bug]: Provider key update silently clears "name" when omitted, then the unique-name index 409s subsequent updates - [#6457](#6457) - [Bug]: OpenCode chat endpoints drop max completion limit
