  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`.

- 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.

## 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 },
    },
  });
  ```
