What is Flux Kontext Pro?
Flux Kontext Pro is Black Forest Labs' specialized model for image-to-image transformation. Unlike text-to-image models that create from scratch, Kontext Pro takes an existing image and modifies it based on your text instructions, opening up powerful editing possibilities.

Style Transfer
Apply artistic styles while preserving content:
- Convert photos to illustrations

How Kontext Pro Works
Understanding Context
The model analyzes your input image to understand:
- Scene composition and layout
- Subject matter and objects present
- Lighting and color relationships
- Overall style and aesthetic
Applying Transformations
Based on your prompt, it then:
- Identifies which elements to preserve
- Determines what needs to change
- Generates modifications that blend naturally
- Maintains coherent lighting and perspective

Writing Effective Transformation Prompts
Be Specific About Changes
Good prompt:
"Transform the background into a cozy coffee shop interior with warm lighting, keep the person and their outfit exactly the same"
Vague prompt to avoid:
"Make it look different"
Specify What to Preserve
Tell the model what shouldn't change:
- "Keep the subject's face unchanged"
- "Maintain the same composition"
- "Preserve the original lighting direction"
- "Don't modify the foreground objects"
Use Style References
Be explicit about desired styles:
- "In the style of studio photography"
- "Like a 1970s film photograph"
- "Matching a minimalist aesthetic"
- "With dramatic chiaroscuro lighting"
