Flux Kontext
FLUX Kontext is Black Forest Labs' in-context image model, available in FluxoKit's browser studio with no BFL account. It reads an image and an instruction together to make coherent changes, and costs from 5 credits per image on the Pro variant up to 10 on Max, on plans starting at $14 per month.

Overview
FLUX Kontext is the in-context member of the FLUX family, and FluxoKit runs it in the browser with credit pricing instead of an API key. Its idea is that an image and an instruction belong together: Kontext looks at the reference and the prompt as one context, so changes stay coherent with what was already there instead of ignoring it.
This page documents FLUX Kontext's variants and their exact per-image costs. The shared corpus that shows one brand brief across sibling models is still being generated for Kontext through the provider batch, so no image here is presented as a finished on-page example yet.
What you can build with FLUX Kontext
Kontext shines on instruction-plus-image work: take a scene and re-light it, restyle a subject while keeping the composition, or extend a frame in a way that matches the original. Because it reasons over the image and the words together, the output reads as a coherent evolution of the input rather than a fresh guess.
It runs in two variants: Pro for the everyday cost-quality balance and Max when the result needs the extra fidelity. Both take the same in-context prompt, so you choose the tier by how much finish the frame has to carry.
Where FLUX Kontext earns its credits
Design teams use FLUX Kontext for coherent restyles and controlled variations that keep a layout intact. Product teams use it to explore lighting and material changes on a fixed composition. Pro runs at 5 credits and Max at 10, and every generation shows its exact cost in your history so tier choices stay visible.
FLUX Kontext vs FLUX Kontext Edit, FLUX 2 Pro, and GPT Image 2
Kontext Edit is the dedicated mask-free editing mode for targeted changes to an existing image. Kontext is the broader in-context generation model; pick Edit when the task is a precise change to one element.
FLUX 2 Pro is the newer FLUX.2 flagship for final-art finish from a prompt. Kontext's edge is reasoning over a reference image and instruction together.
GPT Image 2 leads on prompt comprehension and in-image text from scratch. Kontext leads when the job starts from an existing image that must stay coherent.

Frequently asked questions
›How much does FLUX Kontext cost per image?
FLUX Kontext costs 5 credits per image on the Pro variant and 10 on Max on FluxoKit. Plans start at $14 per month and every generation shows its exact credit cost in your history. There is no BFL API key.
›What is FLUX Kontext best at?
In-context work: reading an image and an instruction together to make coherent changes like re-lighting, restyling, or extending a frame while keeping the original composition intact.
›What is the difference between FLUX Kontext Pro and Max?
Pro is the everyday cost-quality balance at 5 credits per image; Max delivers extra fidelity at 10 credits. Both take the same in-context prompt, so pick the tier by how much finish the frame needs.
