- Line 76: Update the regression test’s existing discovery stub to set
liveModels to true and return deepseek-ai/DeepSeek-V4.1-Flash through live
discovery instead of relying on the static model list. Ensure the test exercises
the discovered Baseten row and still verifies that it does not advertise
text.verbosity.

Baseten documents its Model APIs as Chat Completions compatible. `text.verbosity` is an OpenAI Responses parameter, so there is nothing on that wire for it to become, but the Baseten registry entry carried no opt-out and every routed row serialized support_verbosity: true with default_verbosity: "low". Codex seeds its picker from that and sends text.verbosity on the turn. Provider-wide rather than per-model, matching the xAI and Ollama opt-outs: Baseten's catalog is live-discovered, so a slug that arrives later supports it no more than the seeded ones do. Closes lidge-jun#4630

Approved on exact head 29996e108d5421d55334d35d23d20535459f9f18. The provider-wide opt-out matches the Baseten Model APIs Chat Completions wire: routed rows must not advertise the Responses-only text.verbosity control. The static and genuinely live-discovered cases both prove the default is removed for present and future slugs, the review thread is resolved, and exact-head cross-platform CI is green. The cancelled duplicate target-gate run is superseded by a successful target-gate run at the same SHA. No Go counterpart is applicable to this registry/catalog-only TypeScript provider correction.

Closes #4630.
Summary
text.verbosityis an OpenAI Responses parameter, so there is nothing on that wire for it to become — but the Baseten registry entry carried no opt-out, so every routed row serializedsupport_verbosity: truewithdefault_verbosity: "low", and Codex seeds its picker from exactly that.supportsVerbosity: falseto thebasetenentry insrc/providers/registry/entries-extended.ts(the leaf, post-refactor(src): split the remaining five oversized modules behind facades #4655 — not the old monolithicregistry.ts).tests/codex-integration/catalog-verbosity-default.test.ts, alongside the existing xAI and Kiro ones.Provider-wide, not per-model, matching how xAI (
entries-core.ts:250) and Ollama (entries-extended.ts:831) already spell their opt-outs, and for the reason Ollama's comment gives: Baseten isliveModels: true, so a slug discovered tomorrow supportstext.verbosityno more than this one. Pinning it per-model would leave the next discovered id advertising the control again.Reproduced before fixing
Wrote the assertion first and watched it go red on unmodified
dev:So the catalog really does advertise the control today — that isn't inferred from the registry entry, it's the serialized row.
The live-discovery case, from review
@coderabbitai and @lidge-jun both pointed out that the original test seeded a static
modelslist withliveModels: false, which meant the "tomorrow's slug" reasoning above was a comment rather than something the suite checked — and live discovery is the authoritative path for this provider.Added a second case that seeds no models and lets a stubbed
/modelsresponse supply the slug. Mutation-checked: removingsupportsVerbosity: falsefrom the registry now fails both cases, so the provider-wide claim is pinned on the path that actually matters.One correction to the issue, which does not change the fix
The report attributes the 400 to OpenCodex: "OpenCodex rejects the request while converting it to the Baseten Chat Completions route." I don't think that's where it comes from.
Failed to convert responses requestappears nowhere in this repository.src/chat/norsrc/responses/mentionsverbosityat all — the only stripper is insrc/adapters/openai-responses.ts:428, which is the Responses adapter, not the Chat one.So the message reads like Baseten's own Responses→Chat shim rejecting it upstream, not our converter. Worth pinning down if you're tracking who 400s, but it doesn't move the fix either way: advertising a capability the routed wire cannot carry is wrong whichever side refuses it, and this makes the catalog honest at the source.
Scope I left alone
31 other
adapter: "openai-chat"providers also have nosupportsVerbosityopt-out (openrouter, deepseek, moonshot, commandcode, nvidia, …). That may well be the same class of bug, but "Chat adapter" isn't proof on its own — several of those front gateways that do accept a Responses-shaped body — and a blanket sweep on one reproduced report would be guessing at 31 upstream contracts. @lidge-jun agreed this belongs in a separate issue; happy to open it.Verification
