TanStack AI Structured Outputs

Forbids provider-level json_schema you already set

TanStack · MIT

When

Structured outputs with TanStack AI via JSON Schema, Zod, ArkType, or Valibot. Do not also set provider-level json_schema when the SDK already owns the schema. Pinned 0.42.0. Not Vercel AI SDK generateObject.

The Catch

Forbids provider-level json_schema you already set on the SDK. Distinct from tool-calling. OSS 0 USD; provider keys still required. Pinned 0.42.0.
