Key Capabilities

FLUX.1 Kontext Pro delivers surgical precision for complex image editing workflows.

• In-Context Generation: Processes both text prompts and reference images simultaneously for guided creation.
• Character Consistency: Maintains facial features and object identity across completely different environments and scenes.
• Localized Editing: Performs targeted modifications to specific elements without affecting surrounding areas.
• Iterative Refinement: Enables step-by-step image creation with minimal latency between edits.
• Style Preservation: Generates novel scenes while maintaining unique visual styles from reference images.

Optimal Use Cases

• Marketing: Personalized brand avatars, product placement across multiple contexts without additional photo shoots.
• Content Creation: Social media content, YouTube thumbnails, and platform-optimized visuals.
• Professional Editing: Complex image modifications requiring character continuity and precision.
• Storytelling: Visual narratives with consistent characters across different scenes and environments.
• Education: Custom visual aids and interactive learning materials with contextual modifications.

Parameters

• prompt [str]: The text prompt describing the content, style, or composition of the image to be generated.
• num_images [int]: The number of images to generate
• seed [int]: The random seed for image generation
• aspect_ratio [ 21:9, 16:9, 4:3, 3:2, 1:1, 2:3, 3:4, 9:16, 9:21 ]: The aspect ratio for the image
• guidance_scale [1-20]: The CFG (Classifier Free Guidance) scale is a measure of how close you want the model to stick to your prompt when looking for a related image to show you.
• safety_tolerance [1-6]: The safety tolerance level for the generated image. 1 being the most strict and 5 being the most permissive.
