# Image generation

Image generation starts with the model list. Synchronous APIs return images directly; asynchronous APIs return a task ID first.

<Info>
  If you do not have an API Key yet, read [Get API Key](/en/use/api-key) first.

## Generation vs editing

* Image generation creates new images from a text prompt.
* Image editing modifies an existing image. It requires an `image` input and may also use a `mask`.

## Integration order

1. Call [Image generation models](/api-reference/get-api-ai-models-image-generation).
2. Copy `data[n].name` from the model list and pass it as `model`.
3. Choose size, quality, and style from the same model item.
4. Call [Generate image](/api-reference/post-api-ai-image-generate), or call [Async image generation](/api-reference/post-api-ai-image-generate-async).
5. For async requests, use `data.logId` to call [Image task status](/api-reference/get-api-ai-image-task-log-id).

## Image editing

Image editing uses a separate model list. Call [Image editing models](/api-reference/get-api-ai-models-image-edit), then use [Edit image](/api-reference/post-api-ai-image-edit) or [Async image editing](/api-reference/post-api-ai-image-edit-async).

If the source image or mask is local or private, use [OSS upload](/en/use/oss-upload) first.
