# Reve 2.1

Reve 2.1 is Reve's flagship image model for generation and editing, built around a layout-based intermediate representation that makes image structure directly addressable. It is designed for dense scenes, fine typography, and precise iterative edits at native 4K, with stronger prompt understanding, world knowledge, and foreign-text rendering than Reve 2.0.

- **ID**: `reve:2@1`
- **Status**: live
- **Creator**: Reve
- **Release Date**: July 9, 2026
- **Capabilities**: Text to Image, Image to Image, Edit, Checkpoint

## Pricing

Pricing starts at $0.2 per image generated

- **4k**: `$0.2`

## Compatibility & Validation

`width` and `height` must be used together.

---

The following dimension combinations are supported:

| Configuration | Dimensions |

## Notes

Reve 2.1 handles text-to-image and image-to-image through a single prompt and an optional reference list:

- **Text-to-Image:** Provide a `positivePrompt`. `width` and `height` are optional. Omit them to let the model choose the output dimensions from the prompt, or set them to one of the supported pairs.
- **Image-to-Image:** Add up to 8 images via `inputs.referenceImages` and address each one in the prompt by its 0-based index with a `<frame>N</frame>` tag (`<frame>0</frame>` is the first reference).

Edit and remix are the same request. The prompt decides how much of a reference is kept:

- **Editing** preserves the source and changes only what the prompt targets. "Change the wall in `<frame>0</frame>` to sage green" returns the same scene with just the wall repainted.
- **Remixing** regenerates a new image while keeping the referenced subject. "The handbag from `<frame>0</frame>` on a model walking a sunlit street" keeps the product's identity in an entirely new shot.

## Request Parameters

**API Options**

Platform-level options for task execution and delivery.

### [taskType](https://runware.ai/docs/models/reve-2-1#request-tasktype)

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

Identifier for the type of task being performed

### [taskUUID](https://runware.ai/docs/models/reve-2-1#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/reve-2-1#request-outputtype)

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

Image output type.

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

### [outputFormat](https://runware.ai/docs/models/reve-2-1#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/reve-2-1#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/reve-2-1#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.

- [Webhooks](https://runware.ai/docs/platform/webhooks) (platform)

### [deliveryMethod](https://runware.ai/docs/models/reve-2-1#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.

### [uploadEndpoint](https://runware.ai/docs/models/reve-2-1#request-uploadendpoint)

- **Type**: `string`
- **Format**: `uri`

Specifies a URL where the generated content will be automatically uploaded using the HTTP PUT method. The raw binary data of the media file is sent directly as the request body. For secure uploads to cloud storage, use presigned URLs that include temporary authentication credentials.

**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
https://your-bucket.s3.amazonaws.com/generated/content.mp4?X-Amz-Signature=abc123&X-Amz-Expires=3600

// Google Cloud Storage presigned URL
https://storage.googleapis.com/your-bucket/content.jpg?X-Goog-Signature=xyz789

// Custom storage endpoint
https://storage.example.com/uploads/generated-image.jpg
