# `experimental_cancelBatch()`

<Note type="warning">
  Batch support is experimental and the API may change in patch releases.
</Note>

Requests cancellation of an asynchronous batch. A successful call means that
the provider accepted the cancellation request, not that cancellation has
finished. For a complete guide to the batch lifecycle, see
[Batch](/docs/ai-sdk-core/batch).

```ts
import { experimental_cancelBatch as cancelBatch } from 'ai';

const result = await cancelBatch({
  provider,
  batch,
});

console.log(result.providerMetadata);
```

Calling this function with a provider that does not support batch cancellation
throws an `UnsupportedFunctionalityError`.
