FLUX.1 Kontext

  • Landscape

    Misty pine forest at dawn, low fog between the trunks, cold blue light, wide shot

Why FLUX.1 Kontext on AI Image Tools

  • Built for editing, not for starting from nothing

    Give it a photo and an instruction. It is the model the site reaches for whenever the job is "change this part, keep the rest", which is most of the toolkit.

  • The fastest option on the site

    Our edit runs came back in 18 to 27 seconds. Nano Banana, at the same price, can take several minutes on the same job when it is busy.

  • One image in, by design

    Its input field takes a single image rather than a list. That is why Virtual Try-On does not offer it: it would see the person and have to guess the garment.

  • Same 5 credits as the cheapest tier

    Speed here does not cost extra. Spend the difference on running two variations instead of one.

Every image model in one place

Pick any of these from the Model menu above; the price is shown before you generate. Each name links to what that model is good at. Compare every tier.

How to use FLUX.1 Kontext

  1. Step 1

    Upload the photo

    JPG, PNG, WebP or HEIC up to 10 MB. Phone photos are fine.

  2. Step 2

    Name one change

    "Make it winter, keep the building and the people exactly as they are." One change per run beats a list of five.

  3. Step 3

    Compare and iterate

    Each run is cheap and quick, so stack edits across runs instead of writing one long prompt.

How to write a prompt for FLUX.1 Kontext

  • One change per run

    It is fast and cheap enough that chaining beats stacking. Each pass gives you something to check.

  • Say what must stay

    "Keep the face, pose and background" is the single most useful sentence you can add to an edit prompt.

  • Describe the result, not the process

    "The wall is painted sage green" works better than "repaint the wall".

  • Match the light

    If you add an object, say where the light comes from so it sits in the scene instead of floating on top.

FLUX.1 Kontext: frequently asked questions

What is FLUX.1 Kontext?

An image editing model from Black Forest Labs, the lab behind the FLUX family. It takes a photo plus an instruction and returns the photo with that one change applied.

How is it different from Nano Banana?

Both cost 5 credits. Kontext is considerably faster on edits, 18 to 27 seconds against several minutes in our runs. Nano Banana follows long instructions more literally and can read several reference images; Kontext takes one.

Can it generate an image from text alone?

Yes, it is offered in Text to Image as well. Its strength is editing, but it will generate from a prompt.

Why can't I choose it for Virtual Try-On?

That tool needs a model that reads two images, the person and the garment. Kontext takes a single image, so it would never see the garment and would invent one instead. It is left out of that dropdown on purpose.

Does it keep faces recognisable?

On single-subject edits, yes, especially when you tell it to. Add "keep the face exactly the same" and check the result at full size.

What happens if a run fails?

You are only charged when an image comes back. A failed or timed-out run costs nothing.
