Black Forest Labs FLUX.1 Kontext
FLUX.1 Kontext — Edit Images with Plain Instructions
Black Forest Labs’ editing specialist: upload a photo, say what changes, keep everything else.
FLUX.1 Kontext is Black Forest Labs’ in-context editing model, released on May 29, 2025 as a different kind of image model: instead of generating from scratch, it understands an existing image and modifies it from a plain-language instruction. No masks, no layers, no fine-tuning. On Nano Banana AI, FLUX.1 Kontext is on every plan: 25 credits per edit at 1K with the Pro variant, 50 credits at 2K with Max.
What is FLUX.1 Kontext?
Kontext performs in-context generation: you prompt with an image plus text, and the model extracts the visual concepts and re-renders them coherently with your change applied. Swap a background, restyle an object, change clothing, adjust lighting. The subject stays recognizably itself through the edit.
It ships in two API variants, and our resolution tiers map to them directly: the 1K tier runs FLUX.1 Kontext [pro], the fast iterative editor, and the 2K tier runs FLUX.1 Kontext [max], which adds stronger prompt adherence and typography handling at premium quality.
Speed made Kontext popular: BFL measured it up to eight times faster than the leading editors at launch, which matters because editing is iterative by nature. You refine an edit in small steps, and each round trip costs seconds rather than a minute.
Kontext takes exactly one input image per edit. It also does classic text-to-image, but if you are generating from scratch, FLUX.2 (also on every plan) is the newer generator. Use Kontext when the photo already exists and you want it changed.
FLUX.1 Kontext features
Edits from plain instructions
Say the change in a sentence. No masks, no selections, no layer work.
Local edits that stay local
Kontext changes the region you describe and preserves the rest, including faces and composition.
Fast, iterative rounds
Up to 8x faster than comparable editors at launch. Refine in small steps without waiting.
Pro and Max tiers
The 1K tier runs Kontext [pro] for iteration; 2K runs Kontext [max] for final quality and typography.

FLUX.1 Kontext: before and after
The left image was generated with FLUX.1 Kontext, then edited by FLUX.1 Kontext itself using this prompt: “Change the perfume bottle to frosted emerald green glass and switch the marble surface to dark slate, keep the same composition and lighting”.

FLUX.1 Kontext FAQ
What is FLUX.1 Kontext?
FLUX.1 Kontext is Black Forest Labs’ image editing model, released May 29, 2025. It edits an existing photo from a plain-language instruction while preserving everything you did not mention. On Nano Banana AI it costs 25 credits (1K, pro variant) or 50 credits (2K, max variant).
Is FLUX.1 Kontext free?
No. Nano Banana AI has no free tier. Kontext is on every plan, starting with Standard at $9.99/month (1,500 credits, about 60 edits).
How is Kontext different from a normal image generator?
Generators create from scratch; Kontext understands the image you give it. It extracts the subjects and style, applies your instruction, and re-renders coherently, which is why identity and composition survive the edit.
What is the difference between Kontext pro and max?
Pro is the fast iterative editor; max adds stronger prompt adherence, better typography, and premium rendering. Here the 1K tier is pro (25 credits) and the 2K tier is max (50 credits).
How many photos can I upload per edit?
One. Kontext works on a single input image per edit. To composite from several references, use FLUX.2 or Seedream 5.0 Lite instead.
Can FLUX.1 Kontext generate images from text alone?
Yes, it does classic text-to-image too. But for from-scratch generation, FLUX.2 is the newer BFL model; Kontext earns its keep on edits.
FLUX.1 Kontext vs GPT-4o Image for editing: which one?
Kontext for surgical local edits in seconds. GPT-4o Image for whole-image style transfers where a three-to-five-minute wait is acceptable. Both are on Premium; Kontext is also on Standard.
Does Kontext change faces when editing the background?
Preserving untouched regions is its design goal: character consistency through edits is the model’s benchmark strength. Faces stay stable through background and clothing changes.
