- 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`.

- 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.

- 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.

- 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 },
    },
  });
  ```
