# Grok Imagine Image Pro

Grok Imagine Image Pro is the higher quality variant of the Grok Imagine image model developed by xAI. It generates detailed images from text prompts and supports iterative editing of existing images through natural language instructions. The model provides stronger prompt adherence, improved rendering quality, and more reliable control over composition, style, and aspect ratio. It supports multiple image styles and resolutions up to 2K, enabling workflows for design, illustration, and creative prototyping.

- **ID**: `xai:grok-imagine@image-pro`
- **Status**: live
- **Creator**: xAI
- **Release Date**: February 28, 2026
- **Capabilities**: Text to Image, Image to Image, Image Editing

## Pricing

Each image gen costs $0.07 (+$0.002 for input images for editing.)

- **Image gen**: `$0.07`
- **Editing**: `$0.072`

## Compatibility & Validation

Either provide `inputs.referenceImages`, or specify `width/height` or `resolution`.

---

- **Type**: `string`
- **Required**: true
- **Value**: `imageInference`

Identifier for the type of task being performed

### [taskUUID](https://runware.ai/docs/models/xai-grok-imagine-image-pro#request-taskuuid)

- **Type**: `string`
- **Required**: true
- **Format**: `UUID v4`

UUID v4 identifier for tracking tasks and matching async responses. Must be unique per task.

### [outputType](https://runware.ai/docs/models/xai-grok-imagine-image-pro#request-outputtype)

- **Type**: `string`
- **Default**: `URL`

Image output type.

**Allowed values**: `URL` `base64Data` `dataURI`

### [outputFormat](https://runware.ai/docs/models/xai-grok-imagine-image-pro#request-outputformat)

- **Type**: `string`
- **Default**: `JPG`

Specifies the file format of the generated output. The available values depend on the task type and the specific model's capabilities.

- \`JPG\`: Best for photorealistic images with smaller file sizes (no transparency).
- \`PNG\`: Lossless compression, supports high quality and transparency (alpha channel).
- \`WEBP\`: Modern format providing superior compression and transparency support.

> [!NOTE]
> \*\*Transparency\*\*: If you are using features like background removal or LayerDiffuse that require transparency, you must select a format that supports an alpha channel (e.g., \`PNG\`, \`WEBP\`, \`TIFF\`). \`JPG\` does not support transparency.

**Allowed values**: `JPG` `PNG` `WEBP`

### [outputQuality](https://runware.ai/docs/models/xai-grok-imagine-image-pro#request-outputquality)

- **Type**: `integer`
- **Min**: `20`
- **Max**: `99`
- **Default**: `95`

Compression quality of the output. Higher values preserve quality but increase file size.

### [webhookURL](https://runware.ai/docs/models/xai-grok-imagine-image-pro#request-webhookurl)

- **Type**: `string`
- **Format**: `URI`

Specifies a webhook URL where JSON responses will be sent via HTTP POST when generation tasks complete. For batch requests with multiple results, each completed item triggers a separate webhook call as it becomes available.

### [deliveryMethod](https://runware.ai/docs/models/xai-grok-imagine-image-pro#request-deliverymethod)

- **Type**: `string`
- **Default**: `sync`

Determines how the API delivers task results.

**Allowed values**:

- `sync` Returns complete results directly in the API response.
- `async` Returns an immediate acknowledgment with the task UUID. Poll for results using getResponse.

**Common use cases:**

- **Cloud storage**: Upload directly to S3 buckets, Google Cloud Storage, or Azure Blob Storage using presigned URLs.
- **CDN integration**: Upload to content delivery networks for immediate distribution.

```text
// S3 presigned URL for secure upload
