Flux Kontext¶
What it is¶
An internal block that performs text-based image editing using BlackForest Labs' Flux Kontext models.
What it does¶
Takes a prompt describing the desired transformation and optionally a reference image, then returns a new image URL.
How it works¶
The block sends your prompt, image, and settings to the selected Flux Kontext model on Replicate. The service processes the request and returns a link to the edited image.
Inputs¶
| Input | Description |
|---|---|
| Credentials | Replicate API key with permissions for Flux Kontext models |
| Prompt | Text instruction describing the desired edit |
| Input Image | (Optional) Reference image URI (jpeg, png, gif, webp) |
| Aspect Ratio | Aspect ratio of the generated image (e.g. match_input_image, 1:1, 16:9, etc.) |
| Seed | (Optional, advanced) Random seed for reproducible generation |
| Model | Model variant to use: Flux Kontext Pro or Flux Kontext Max |
Outputs¶
| Output | Description |
|---|---|
| image_url | URL of the transformed image |
| error | Error message if generation failed |
Use Cases¶
- Enhance a marketing image by requesting "add soft lighting and a subtle vignette" while providing the original asset as the reference image.
- Generate social media assets with specific aspect ratios and style prompts.
- Apply creative edits to product photos using text instructions.
