docs(llms): rewrite smart routing for the @edenai hardening work - #100
Conversation
`@edenai` no longer forwards the router's failures to the caller, sends only a text digest of the request, and takes a `routing.quality_cost` knob. The page predated all of it, and still recommended gpt-4o. - smart-routing: `router_candidates` as concrete provider/model ids with their bounds and the drop-vs-422 rule, `routing.quality_cost`, what leaves Eden AI, the local-default policy, and the `auto` metadata block - request-metadata: `auto` is now a permanent key of the block - provider-routing: `sort` never changes the model, `quality_cost` does - evals: q11's reference answer matches the page's new scope Documents edenai/aifeatures#553, so it lands ahead of that deploy.

WalkthroughThe pull request updates smart-routing documentation for model ranking, quality-cost controls, fallback behavior, routing metadata, provider selection, and evaluation coverage. It also updates document modification dates and examples. ChangesSmart routing documentation
Estimated code review effort: 3 (Moderate) | ~20 minutes Merge Risk: 🔵 Low · up to The documentation update explains smart-routing behavior, but it still needs follow-up to accurately cover invalid candidate-list errors, provider filtering after ranking, and the documented credential-placeholder convention. These gaps could mislead users about validation, model selection, or example setup, but they are bounded documentation issues rather than runtime risks. Poem

Use the required API-token placeholder in all production examples.
Replace YOUR_API_KEY with the documented production token placeholder. This distinguishes production credentials from sandbox_api_token examples.

Source: Coding guidelines
Review pass over the smart routing page. The published metadata names no vendor, so the prose should not imply one either: "the router" becomes "ranking" throughout, and a failed ranking "applies a default" rather than "chooses locally". Two factual corrections, both verified against the deployed code: - `quality_cost` unset is the default, not `0`. They are different requests: unset sends no knob at all. - The rankable set is not a provider-family rule. `google/gemini-3.7-flash` is dropped while `openai/gpt-4o-mini` is ranked, so the page no longer claims first-party ids rank and resellers do not. Also drops the precise timeout and breaker windows, which are tuning rather than contract, and softens the content-hashing bullet.

Include invalid candidate-list 422 errors.
The expected answer says 422 occurs only when no candidate remains. The source document also returns 422 when router_candidates exceeds 64 entries or an entry exceeds 128 characters. Add these validation cases, including the per-entry length bound.

| Two questions get answered on an `@edenai` request: which model, then which provider serves it. | ||
|
|
||
| When ranking succeeds, it names a provider along with the model, so the second question is already settled. When it cannot rank and Eden AI falls back to one of its default models, that model is a bare name, and [provider routing](/v3/llms/provider-routing) resolves it exactly as if you had sent it yourself: your `routing.sort`, `routing.allowed_providers`, sticky affinity, region and failover all still apply. |

Define how routing.allowed_providers applies to ranked candidates.
smart-routing.mdx:136 says successful ranking fixes the provider/model. provider-routing.mdx:113-123 says excluded providers cannot be used and the request fails when no allowed provider serves the model. Document the behavior when ranking selects an excluded provider, then make both pages consistent.

Documents edenai/aifeatures#553, which hardens
@edenaismart routing. The page predated the whole feature set: three paragraphs, a stalegpt-4o/gemini-2.5-flashrecommendation table, and nothing about failure behaviour, privacy or metadata.This describes post-merge behaviour and is ahead of prod until #553 ships.

Entries the router cannot rank are dropped intoauto.droppedrather than failing the request, with a 422 only when nothing is left. Includes the reseller caveat (azure/gpt-5.5is a valid Eden AI id that is still skipped) and a warning that-latestaliases do not resolve insiderouter_candidates.routing.quality_cost(0 to 10), and why it is the onlyroutingfield that changes which model answers.edenai_metadata.auto, with theselectionvocabulary (ranked,single,default).v3/llms/request-metadata.mdx:autois now a permanent key of the block, so it is in the always-present example (nullthere), the field table, and a short section of its own.v3/llms/provider-routing.mdx: one line statingsortnever changes the model, pointing atquality_cost.
