6 toolsflux_edit_imageInspect
Edit an existing image using Flux with a text prompt.
This allows you to modify an existing image based on a text description.
The kontext models (flux-kontext-pro, flux-kontext-max) are specifically
designed for high-quality image editing and style transfer.
Use this when:
- You want to modify or transform an existing image
- You want to change specific elements in an image
- You want to apply style changes or artistic effects
- You want to add, remove, or replace objects in an image
For generating new images from scratch, use flux_generate_image instead.
Returns:
Task ID and edited image information including URLs.| Name | Required | Description | Default |
|---|---|---|---|
| size | No | Output image size. For kontext models: aspect ratios like '1:1', '16:9'. For other models: pixel dimensions like '1024x1024'. | |
| model | No | Flux model to use for editing. Recommended models for editing: - flux-kontext-pro: Best for context-aware editing and style transfer (recommended) - flux-kontext-max: Maximum context for complex edits - flux-dev: Basic editing support Other models also support editing but kontext models give best results. | flux-kontext-pro |
| prompt | Yes | Description of how to edit the image. Be specific about what changes to make. Examples: 'Change the background to a sunset beach', 'Add sunglasses to the person', 'Make it look like a watercolor painting', 'Replace the car with a bicycle' | |
| image_url | Yes | URL of the image to edit. Must be a direct image URL (JPEG, PNG, etc.), not a web page containing an image. | |
| callback_url | No | Webhook callback URL for asynchronous notifications. |
flux_generate_imageInspect
Generate AI images from a text prompt using Flux.
Flux is a family of fast, high-quality image generation models by Black Forest Labs.
Different models offer different tradeoffs between speed, quality, and capabilities.
Use this when:
- You want to create new images from a text description
- You need high-quality AI-generated artwork or photos
- You want fast image generation with good prompt following
For editing existing images, use flux_edit_image instead.
Returns:
Task ID and generated image information including URLs.| Name | Required | Description | Default |
|---|---|---|---|
| size | No | Image size. For flux-dev/pro/pro-1.1: pixel dimensions like '1024x1024' (256-1440px, multiples of 32). For flux-pro-1.1-ultra and kontext models: aspect ratios like '1:1', '16:9', '9:16', '4:3', '3:2', '2:3', '4:5', '5:4', '3:4', '21:9', '9:21'. Default varies by model. | |
| count | No | Number of images to generate. Only supported for generate action. Default is 1. | |
| model | No | Flux model to use for generation. Options: - flux-dev: Fast development model, good balance of speed and quality (default) - flux-pro: Higher quality production model - flux-pro-1.1: Improved production model with better prompt following - flux-pro-1.1-ultra: Highest quality, supports aspect ratios instead of pixel sizes - flux-kontext-pro: Context-aware model for editing and style transfer - flux-kontext-max: Maximum context model for complex editing tasks | flux-dev |
| prompt | Yes | Description of the image to generate. Be descriptive about style, subject, lighting, and composition. Examples: 'A majestic mountain landscape at golden hour, photorealistic', 'Cyberpunk street scene with neon lights and rain, cinematic', 'Minimalist logo design of a phoenix, vector art style' | |
| callback_url | No | Webhook callback URL for asynchronous notifications. When provided, the API will POST to this URL when the image is generated. |
flux_get_taskInspect
Query the status and result of a Flux image generation task.
Use this to check if a generation is complete and retrieve the resulting
image URLs and metadata.
Use this when:
- You want to check if an image generation has completed
- You need to retrieve image URLs from a previous generation
- You used async callback and want to check results later
- The initial generation returned a task_id without immediate results
Returns:
Task status and generation result including image URLs.| Name | Required | Description | Default |
|---|---|---|---|
| task_id | Yes | The task ID returned from a generation or edit request. This is the 'task_id' field from any flux_generate_image or flux_edit_image tool response. |
flux_get_tasks_batchInspect
Query multiple Flux image generation tasks at once.
Efficiently check the status of multiple tasks in a single request.
More efficient than calling flux_get_task multiple times.
Use this when:
- You have multiple pending generations to check
- You want to get status of several images at once
- You're tracking a batch of generations
Returns:
Status and result information for all queried tasks.| Name | Required | Description | Default |
|---|---|---|---|
| task_ids | Yes | List of task IDs to query. Maximum recommended batch size is 50 tasks. |
flux_list_actionsInspect
List all available Flux tools and their use cases.
Reference guide for what each tool does and when to use it.
Returns:
Categorized list of all tools with descriptions.| Name | Required | Description | Default |
|---|---|---|---|
No parameters | |||
flux_list_modelsInspect
List all available Flux models and their capabilities.
Reference guide for choosing the right Flux model for your use case.
Returns:
Detailed list of all Flux models with descriptions and recommendations.| Name | Required | Description | Default |
|---|---|---|---|
