Edit the Picture, Do Not Replace It
FLUX Kontext exists because "edit this image" and "generate a similar image" are different jobs that most models perform identically.
Ask a generator to change one thing in a photograph and you usually get a plausible new picture back — composition subtly redrawn, details you never mentioned quietly rearranged, the subject almost but not quite the same person. Kontext is built the other way round. Its design goal is to apply the change you named and return everything else recognisably intact.
Use FLUX Kontext when something already exists and needs one specific thing to be different. Swap backgrounds, remove objects, change materials and colours, adjust the light, and chain those changes one at a time so every step stays reviewable.
What Is FLUX Kontext?
FLUX Kontext is an image editing model family developed by Black Forest Labs, offered in Virse as two entries: FLUX Kontext Pro and FLUX Kontext Max. You supply a picture and a written instruction, and the model interprets that instruction in the context of what is already in the frame — which is where the name comes from.
The model is built around three major strengths:
- Preservation by default, so unmentioned areas survive the edit
- Targeting through language rather than through masks or selections
- Chained editing, where each pass builds on the last as a reviewable step
Both entries accept the same inputs and the same instructions, differing in headroom on demanding edits rather than in what they can be asked to do. There is no mask to paint, no region to lasso, and no layer stack to manage.
FLUX Kontext Specs at a Glance
Preservation by Default
Anything you do not mention is meant to come back unchanged.
Two Entries
Kontext Pro for everyday work, Kontext Max for compounded edits.
No Masking Required
Targeting happens in language: name the object and where it sits.
Chainable Passes
Feed a result back in to layer the next change as a separate step.
Shared Instruction Set
A brief written for one entry runs on the other unmodified.
Key Features of the FLUX Kontext AI Image Editor
The Preservation Clause Does Real Work
Naming what must stay is not filler in a Kontext instruction, it is the load-bearing half. The model is built to honour it, which is the behaviour that separates an editing model from a generator handed an input image.
Language as the Selection Tool
"The car on the left" is a valid way to point at something. There is no mask to paint and no path to draw, which removes the step that usually makes small edits not worth doing.
Edits That Compound Cleanly
Because each pass returns a picture rather than a reinterpretation, running five single changes in sequence produces five reviewable states instead of accumulating drift.
Subject Continuity Through Changes
A person or product that has to stay recognisable across a run of edits holds better here than through repeated generation, because nothing is being regenerated.
Two Tiers for Different Loads
Kontext Pro handles the everyday case. Kontext Max carries more headroom for instructions that change several related things at once — a background and the lighting on the subject, or a garment while a pattern survives.
Built for the Second Half of the Work
Most models are optimised for the first image. This one is optimised for the eleventh, which is where finished assets actually get made.
Build with FLUX Kontext in Virse
Editing is iterative and iteration produces near-identical files. Version four is usually the good one, and by version nine nobody can tell them apart from a filename. Virse keeps the chain visible. The source, every intermediate pass, and the final image sit beside each other on one canvas, so an edit that went the wrong way costs a single step rather than the whole thread.
See the Chain, Not the Last Frame
Every pass stays laid out in order, which makes it obvious where a sequence stopped improving.
Correct What Another Model Nearly Got Right
A near-miss from an expensive generator is often cheaper to fix here than to regenerate there, and the fix happens without leaving the canvas.
Access 30+ Creative Models
Move between FLUX Kontext and 30+ other image and video models without leaving the canvas or rewriting the brief.
Prepare Frames for Video
Adjust an opening frame until it is right, then hand it to Seedance 2.0, Kling 3.0, or Veo 3.1.
What Can You Create with FLUX Kontext?
Background Replacements
Move a subject onto a new backdrop while pose, scale, and lighting survive.
Object Removal
Take an element out and have the space filled with what plausibly belongs there.
Material and Colour Changes
Turn linen into velvet or beige into forest green while shape and shadow hold.
Lighting and Time-of-Day Adjustments
Relight a scene without rebuilding it.
Whole-Image Restyling
Convert a photograph to a drawing while the composition stays exactly in place.
Multi-Step Retouching
Chain a run of single corrections into a finished asset, one reviewable step at a time.
How to Use FLUX Kontext in Virse
Upload the Image
Bring in a photograph, a generated picture, or a frame from elsewhere on the canvas.
Describe One Change
State what should be different, and name what must stay exactly as it is.
Check What Survived
Look at the parts you did not ask about, especially near the edges of the frame.
Chain the Next Change
Feed the result back in for the following edit rather than describing everything at once.
How to Write a FLUX Kontext Prompt
A useful FLUX Kontext prompt usually includes three elements:
- What Changes
- What Stays
- Where It Is
이렇게 쓰는 대신
A woman in a red dress standing in a modern kitchen with marble countertops, natural window light, professional photography.
이렇게 쓰세요
Change the dress to red. Keep the woman's pose, face, hair, and position in the frame exactly as they are, and leave the kitchen and the lighting untouched.
FLUX Kontext Prompt Examples
Object Removal
Remove the two bicycles leaning against the wall on the right side of the image. Fill the space with a continuation of the same brick wall and pavement, matching the existing texture, mortar lines, and shadow direction. Leave the rest of the street, the doorway, and the figure on the left completely unchanged.
Material Change
Change the tabletop from pale oak to dark polished slate. Keep the table's shape, edge profile, and position identical. Keep every object on the table exactly where it is, at the same scale and angle. Update only the reflections and contact shadows on the surface so they read correctly against the new material.
Relight
Change the light in the room from midday overhead to late afternoon entering low from the right. Keep the furniture, the camera position, and every object exactly where it is. Lengthen the shadows to match the new direction and warm the colour temperature slightly. Leave the view through the window unchanged.
FLUX Kontext Pro vs. FLUX Kontext Max
| 비교 항목 | FLUX Kontext Pro | FLUX Kontext Max |
|---|---|---|
| Positioned for | Everyday single-change edits | Compounded or demanding edits |
| Input | Image plus written instruction | Image plus written instruction |
| Instruction set | Identical to Max | Identical to Pro |
| Masking | Not required | Not required |
| Typical use | Volume retouching, background swaps | Several related changes in one pass |
| Switching cost | Brief runs on Max unchanged | Brief runs on Pro unchanged |
Tips for Cleaner Edits
Always Include the Preservation Clause
"Keep everything else unchanged" measurably reduces drift. It is the single most useful habit on this model.
One Change per Pass
Chaining three single edits beats one instruction containing three, and it leaves you three places to step back to.
Describe Position, Not Just Object
"The car on the left" is targetable. "The car" is ambiguous the moment there are two of them.
Check the Corners First
Drift shows up at the edges of the frame, away from where you were looking when you wrote the instruction.
FLUX Kontext FAQ
What is FLUX Kontext?
FLUX Kontext is an image editing model family from Black Forest Labs, available in Virse as FLUX Kontext Pro and FLUX Kontext Max. You supply an image and describe the change in writing.
What is the difference between FLUX Kontext Pro and Max?
Both take the same inputs and the same instructions. Max carries more headroom for edits that change several related things at once, while Pro handles the everyday single-change case.
Is FLUX Kontext free, and what does it cost?
FLUX Kontext is available on Virse's paid plans. Generation draws on a monthly credit allowance rather than a charge per image, and the higher plans make it unmetered within fair use. Current plan rates are listed on the Virse pricing page.
Do I need to mask the area I want to change?
No. Targeting happens in the instruction rather than through a selection tool — name the object and its position instead.
Can FLUX Kontext generate images from scratch?
It is built for editing an existing picture. For text-to-image work in Virse, use FLUX 2 Pro, Nano Banana Pro, or another generator.
Can FLUX Kontext add text to an image?
Not reliably. For readable type inside an image, Nano Banana Pro or Ideogram 4.0 are the models to use.
Can I run several edits in sequence?
Yes, and it is the recommended way to work. Feed each result back in for the next change so every step remains reviewable.
How do I use FLUX Kontext in Virse?
Select Kontext Pro or Kontext Max, upload an image, describe the change along with what should stay, and generate.
Change One Thing, Keep the Rest
Describe the difference instead of rebuilding the picture, and chain the edits so every step stays somewhere you can return to.
