- 98e83ab: Fix `useChat` status briefly flashing to `submitted` on page load when `resume: true` is set and there is no active stream to resume. The `reconnectToStream` check is now performed before setting status to `submitted`, so status stays `ready` when the server responds with 204 (no active stream).

## 6.0.84

### Patch Changes

- 4024a3a: security: prevent unbounded memory growth in download functions

  The `download()` and `downloadBlob()` functions now enforce a default 2 GiB size limit when downloading from user-provided URLs. Downloads that exceed this limit are aborted with a `DownloadError` instead of consuming unbounded memory and crashing the process. The `abortSignal` parameter is now passed through to `fetch()` in all download call sites.

  Added `download` option to `transcribe()` and `experimental_generateVideo()` for providing a custom download function. Use the new `createDownload({ maxBytes })` factory to configure download size limits.

### Patch Changes

- 59fcf30: fix(ai): make experimental_context required in ToolLoopAgentOnFinishCallback

  This fixes a type inconsistency where `ToolLoopAgentOnFinishCallback` had `experimental_context` as optional while `StreamTextOnFinishCallback` and `GenerateTextOnFinishCallback` had it as required. Since `ToolLoopAgent` delegates to `streamText`/`generateText`, and both always pass `experimental_context` when invoking the callback, the types should match.

### Patch Changes

- ab57783: Add usage information to onFinish callback in useChat

## 6.0.39

### Patch Changes

- 4e28ba0: fix(ai): propagate providerMetadata during input-streaming state

  Provider-executed tools (like MCP tools) need to send metadata during the streaming phase, but the implementation only set `callProviderMetadata` when `part.state === "input-available"`. This fix removes the overly-restrictive state check and adds `callProviderMetadata` to the input-streaming state types and schemas.

## 6.0.38

### Patch Changes

- Updated dependencies [5c090e7]
  - @ai-sdk/provider@3.0.4
  - @ai-sdk/gateway@3.0.16
  - @ai-sdk/provider-utils@4.0.8

## 6.0.37

### Patch Changes

- b5dab9b: fix(ai): maintain OpenTelemetry context across async generator yields

  Fixes an issue where OpenTelemetry context was lost at async generator yield boundaries, causing nested ToolLoopAgent spans to escape to the parent agent's level in observability platforms.

  The fix ensures that when `recordSpan` is used with async generators (e.g., in tool execution), the active context is explicitly maintained using `context.with()`, preventing span hierarchy corruption in nested agent scenarios.

  Closes #11720

### Patch Changes

- a7b2e66: Added providerOptions to agent stream and generate calls
- 9bed210: ### `extractReasoningMiddleware()`: delay sending `text-start` chunk to prevent rendering final text before reasoning

  When wrapping a text stream in `extractReasoningMiddleware()`, delay queing the `text-start` chunk until either `reasoning-start` chunk was queued or the first `text-delta` chunk is about to be queued, whichever comes first.

- 516be5b: ### Move Image Model Settings into generate options

  Image Models no longer have settings. Instead, `maxImagesPerCall` can be passed directly to `generateImage()`. All other image settings can be passed to `providerOptions[provider]`.

  Before

  ```js
  await generateImage({
    model: luma.image("photon-flash-1", {
      maxImagesPerCall: 5,
      pollIntervalMillis: 500,
    }),
    prompt,
    n: 10,
  });
  ```

  After

  ```js
  await generateImage({
    model: luma.image("photon-flash-1"),
    prompt,
    n: 10,
    maxImagesPerCall: 5,
    providerOptions: {
      luma: { pollIntervalMillis: 5 },
    },
  });
  ```

  Before [zod@3.25.49](https://github.com/colinhacks/zod/releases/tag/v3.25.49), requests to Google's APIs failed due to a missing `type` in the provided schema. The problem has been resolved for the `ai` SDK by bumping our `zod` peer dependencies to `^3.25.49`.

  Added automatic support for respecting rate limit headers (`retry-after-ms` and `retry-after`) in the SDK's retry logic. When these headers are present and contain reasonable values (0-60 seconds), the retry mechanism will use the server-specified delay instead of exponential backoff. This matches the behavior of Anthropic and OpenAI client SDKs and improves rate limit handling without requiring any API changes.

## 5.0.0-beta.20

### Patch Changes

- 4c8f834: feat: automatically respect rate limit headers in retry logic

  Added automatic support for respecting rate limit headers (`retry-after-ms` and `retry-after`) in the SDK's retry logic. When these headers are present and contain reasonable values (0-60 seconds), the retry mechanism will use the server-specified delay instead of exponential backoff. This matches the behavior of Anthropic and OpenAI client SDKs and improves rate limit handling without requiring any API changes.

  Image Models no longer have settings. Instead, `maxImagesPerCall` can be passed directly to `generateImage()`. All other image settings can be passed to `providerOptions[provider]`.

  Before

  ```js
  await generateImage({
    model: luma.image("photon-flash-1", {
      maxImagesPerCall: 5,
      pollIntervalMillis: 500,
    }),
    prompt,
    n: 10,
  });
  ```

  After

  ```js
  await generateImage({
    model: luma.image("photon-flash-1"),
    prompt,
    n: 10,
    maxImagesPerCall: 5,
    providerOptions: {
      luma: { pollIntervalMillis: 5 },
    },
  });
  ```

## 2.2.2

### Patch Changes

- 84e0cc8: Add experimental_StreamData and new opt-in wire protocol to enable streaming additional data. See https://github.com/vercel/ai/pull/425.

  Changes `onCompletion` back to run every completion, including recursive function calls. Adds an `onFinish` callback that runs once everything has streamed.

  If you're using experimental function handlers on the server _and_ caching via `onCompletion`,
  you may want to adjust your caching code to account for recursive calls so the same key isn't used.

  ```
  let depth = 0

  const stream = OpenAIStream(response, {
      async onCompletion(completion) {
        depth++
        await kv.set(key + '_' + depth, completion)
        await kv.expire(key + '_' + depth, 60 * 60)
      }
    })
