What Is FLUX.1 Kontext ? Everything You Need to Know About This New Model


Ever tried updating something in a photo - like changing text or colors - only to end up repainting half the thing in Photoshop? Yeah, frustrating. FLUX.1 Kontext by Black Forest Labs is different. It lets you update only what needs changing, while everything else stays put. It's clean, fast, and precise - like having a smart editor built into your image.
What FLUX.1 Kontext Actually Is (and Why It Matters)
Imagine commissioning a painting from scratch every time you wanted to tweak something - new canvas, new brushstrokes, start over entirely. That’s how most AI image tools used to work. You’d give it a new prompt, and it would try to rebuild the whole image, often tossing out the things you actually liked.
FLUX.1 Kontext flips that idea on its head.
Instead of regenerating the whole image, Kontext lets you edit what's already there - surgically, precisely, and in context. Say you want to change the color of a car, remove a logo, or fix a sign. You just tell it what to do: “Turn the car red,” “Take out the person in the background". The model understands your instruction, modifies only that part, and leaves everything else untouched - lighting, layout, textures, and style stay exactly how you had them.

Before this, tools like image-to-image generation or inpainting were your best bet - but both had tradeoffs. Inpainting made you mask areas manually and often gave you weird seams or mismatched lighting. Image-to-image prompts were more flexible but wiped the canvas clean each time. Kontext brings the best of both worlds with none of the hassle.
There are three flavors of the model depending on how you want to use it:
- FLUX.1 Kontext [max] and [pro] are API-based and built for creators who need speed and precision in their workflow.
- FLUX.1 Kontext [dev] is open-weight and ideal for experimentation or research use under the non-commercial license.
The result? You don’t have to fight the tool. You just talk to it - and it gets it right.
How It Works: Versions and Speed
Three versions available:
- Dev - open-weight, non-commercial research use
- Pro - fast API version (~8-10s per edit, $0.04/image)
- Max - top-tier speed and precision (~10-12s, $0.08/image)
Sub-10-second edits keep the creative flow going.
Better and cheaper than GPT-Image-1 or ByteDance BAGEL - both slower and less consistent.
Model | Speed | Cost/image | Character Consistency | Text Handling | Iterative Editing |
---|---|---|---|---|---|
FLUX.1 Kontext Dev | ~6-10s | TBD | Excellent | Excellent | Yes |
FLUX.1 Kontext Pro | ~8-10s | $0.04 | Excellent | Excellent | Yes |
FLUX.1 Kontext Max | ~10-12s | $0.08 | Excellent | Excellent | Yes |
ByteDance BAGEL | ~40s | $0.10 | Good | Good | Limited |
What It Can Do
- Character Consistency - Keep the same face or person across edits
- Precise Object Edits - “Change car color,” “Remove background object”
- Text Replacement - Perfect for turning SALE into SOLD without messing up fonts
- Iterative Changes - Build edits step-by-step without losing context
- Style Transfer - Swap in watercolor, pop-art, or anime styles while preserving layout

How to Write Edits That Stick
- Use action words: Change, Add, Remove, Replace
- For text swaps, use quotes:
- ✔ Good:
Replace "SALE" with "SOLD"
- ❌ Not as good:
Change the sign to SOLD
- ✔ Good:
- One edit at a time: Don’t ask for ten changes in a single prompt.
- Be style-specific:
Convert to watercolor while maintaining composition
keeps things tidy.
