docs(routing): semantic complexity router helm values, OpenAPI, and documentation - #6168
Conversation
📝 WalkthroughSummary by CodeRabbit
WalkthroughThis PR documents semantic three-tier complexity classification, embedding configuration, classifier lifecycle APIs, routing-log filters, observability fields, and Helm support for the Chromem vector store. Legacy lexical configuration remains documented for compatibility. ChangesSemantic Complexity Router
Estimated code review effort: 4 (Complex) | ~45 minutes Merge Risk: 🟡 Moderate · up to The PR changes semantic complexity-routing configuration and documentation but leaves API schemas accepting invalid timeout, similarity, history-window, and overlong phrase values, while several user-facing references remain incomplete. This can cause clients or deployments to accept configurations that later fail validation; merge should wait for schema and documentation parity fixes. Possibly related PRs

The description states each phrase is limited to 2000 characters. The items schema does not express that limit. Generated clients and request validators will accept longer phrases and fail at the server.

| | Field | Values | Meaning | | ||
| |---|---|---| | ||
| | `complexity_tier` | `SIMPLE`, `MEDIUM`, `COMPLEX` | The tier the request was classified into | | ||
| | `complexity_mechanism` | `semantic`, `skipped` | How the tier was produced. `semantic` means an embedding match produced the tier; `skipped` means a rule demanded a tier but classification produced none (classifier not configured or not ready, unsupported input, embedding failure/timeout, or a match below `min_similarity`) | | ||
| | `complexity_score` | 0.0 – 1.0 | The similarity score of the nearest reference phrase | | ||
|
|
||
| You will see log lines like `Complexity: tier=REASONING score=0.38 words=25`. If no configured complexity signal matches the latest user message, the routing log records that complexity analysis was skipped and routing continues on the existing path. This lets you audit how traffic is being distributed and spot mis-classifications to tune thresholds or keyword lists. | ||
| The routing decision logs also record the matched reference phrase alongside the tier and similarity, so you can tell a genuine match from an accidental one. Long phrases are truncated to 120 characters in the log line. | ||
|
|
||
| For example, a successful match is recorded as: | ||
|
|
||
| ```text | ||
| Semantic complexity: tier=MEDIUM similarity=0.62 matched="produce a customer-facing incident summary from an already established cause and remediation." | ||
| ``` | ||
|
|
||
| These fields are only set when a routing rule actually referenced `complexity_tier`; requests that never touched a complexity rule carry no complexity fields. | ||
|
|
||
| ### In the log explorer | ||
|
|
||
| The log detail view shows **Complexity Tier** (as a colored badge), **Complexity Mechanism**, and **Complexity Score** in the request overview. The logs filter sidebar can filter by **Complexity Tier** and **Complexity Mechanism**, so you can audit how traffic is being distributed and spot mis-classifications to tune your phrase lists or similarity floor. The same filters are available on the logs API as comma-separated query parameters: | ||
|
|
||
| ```bash | ||
| curl "http://localhost:8080/api/logs?complexity_tiers=COMPLEX&complexity_mechanisms=semantic" | ||
| ``` | ||
|
|
||
| <Note> | ||
| The raw `complexity_score` is displayed but not filterable; tier and mechanism are the supported filter dimensions. The mechanism filter offers `semantic` and `skipped`. Legacy `REASONING` tiers remain available in the logs filter. | ||

Update the schema fields timeout, min_similarity, and message_history_count with
the requested numeric bounds: timeout numbers must be nonnegative,
min_similarity must be at least 0 and below 1, and message_history_count must be

duration values while preserving support for duration strings such as “1.5s”.

Summary
Replaces the Complexity Router's lexical keyword scorer with a semantic (embedding-based) classifier. Instead of matching weighted keyword lists across four tiers, Bifrost now embeds each incoming request and assigns it the tier of its nearest reference phrase across three tiers: Simple, Medium, and Complex. The Reasoning tier is retired and merged into Complex.
Changes
complexity_tier. Classification runs lazily — only when a routing rule actually referencescomplexity_tier.REASONINGlog rows remain queryable but are never emitted for new requests.keywordsblock now holds whole example prompts per tier (simple_keywords,medium_keywords,complex_keywords) rather than individual scoring keywords. 150 built-in default phrases (50 per tier) ship with the classifier. The old four-list shape (code_keywords,technical_keywords,reasoning_keywords,simple_keywords) remains accepted for backward compatibility and is mapped into the three-list shape on load.semanticconfiguration block: A newsemanticblock configures the embedding provider, model, timeout, similarity floor (min_similarity), conversation history window (message_history_count), budget tracking, and phrase vector storage (embeddedorvector_store).GET /api/routing/complexity-analyzer-statusendpoint (and UI badge) reportsdisabled,warming,ready, orfailed, with progress counters and aserving_previousflag so the last good generation keeps routing while a new one warms.tier_boundariesdeprecated: Numeric score thresholds are optional, ignored by semantic routing, and accepted only so existing configurations continue to load without error.vectorStore.type: chromemsupport in Helm, with avectorStore.chromemblock (path,compress) for the embedded in-process vector store used by semantic complexity routing.complexity_tier,complexity_mechanism(semanticorskipped), andcomplexity_score. These fields are also emitted as Prometheus labels and OpenTelemetry span attributes. Two new Prometheus counters track embedding call volume and cost:bifrost_routing_embedding_requests_totalandbifrost_routing_embedding_cost_total. Datadog tagscomplexity_tierandcomplexity_mechanismare added. All log and histogram API endpoints acceptcomplexity_tiersandcomplexity_mechanismsas comma-separated query filters.ComplexityAnalyzerConfigupdated to reflect the newsemanticblock and three-listkeywordsshape.ComplexitySemanticConfigandComplexitySemanticStatusschemas added.tier_boundariesand legacy keyword fields marked deprecated.GET /api/routing/complexity-analyzer-statusendpoint added.bifrost.governance.complexityAnalyzerConfigupdated with commented examples for the newsemanticblock and three-tier keyword lists.

The lexical scorer no longer runs. Existing deployments that relied on
tier_boundariesand keyword-based scoring will seecomplexity_mechanism: skippedand no tier published until asemanticblock is configured with an embedding provider and model. TheREASONINGtier is retired — routing rules matchingcomplexity_tier == "REASONING"will never match on new requests and should be updated tocomplexity_tier == "COMPLEX". Legacy configurations parse and validate without error; no startup failures are introduced.Related issues
Security considerations
The classifier status endpoint (
GET /api/routing/complexity-analyzer-status) never returns phrases, embeddings, or provider secrets. Embedding calls are made inline to the configured provider using the existing key management path; no new credential surfaces are introduced.Checklist
