# StructuredOutputCompleteEvent

# Interface: StructuredOutputCompleteEvent\<T\>

Defined in: [packages/typescript/ai/src/types.ts:1149](https://github.com/TanStack/ai/blob/main/packages/typescript/ai/src/types.ts#L1149)

Final event of a streaming structured-output run. Carries the validated
`object` (typed as `T` after the orchestrator runs Standard Schema parsing),
the `raw` JSON text that produced it, and — for thinking/reasoning models —
the accumulated reasoning text. Adapters emit this with `T = unknown`; the
chat orchestrator narrows to the schema's inferred type after validation.

`reasoning` is `undefined` when the model produced none (most non-thinking
models) and when the underlying adapter doesn't expose reasoning streams.

`name` is a string literal so consumers can narrow directly:

```ts
if (chunk.type === 'CUSTOM' && chunk.name === 'structured-output.complete') {
  chunk.value.object // typed as T
}
```
