What is FLUX.1 Kontext Dev?
FLUX.1 Kontext Dev is Black Forest Labs’ instruction-based image-editing model. It works from an input image and text to modify objects, scene details or visual style while using the original image as context.
The official demo includes an upload field, a prompt, guidance, steps and seed controls. Its Reuse this image button lets you continue editing a generated result. Check each intermediate output before making another change.
This is the Dev model rather than Kontext Pro or Max. Its public demo and its model license have separate terms; a free browser session does not imply unrestricted use of the model weights.

FLUX.1 Kontext Dev FAQ
Inputs, generation settings, account requirements and troubleshooting.
Is FLUX.1 Kontext Dev free to use here?
The public demo can be used within its Hugging Face GPU allowance. Free use is limited by the hosting provider’s quotas and shared capacity; it is not unlimited. Image Toolkit does not sell credits for this embedded tool.
What does Reuse this image do?
It places the generated result back into the editing workflow so you can apply another instruction. Repeated edits can gradually change details you wanted to preserve.
Is this Kontext Pro or Kontext Max?
No. This page embeds FLUX.1 Kontext Dev, the open-weight development model. It does not provide the paid Pro or Max API.
Can I change style while keeping the composition?
The model supports style edits. Describe the target style and explicitly identify the composition, objects or colors that should remain. Inspect the result for unintended changes.
Do I need an account or API key for FLUX.1 Kontext Dev?
No Image Toolkit account or API key is needed to open the tool. Hugging Face may require sign-in to generate images and controls the available GPU allowance. Follow the access message inside the demo.
Why is FLUX.1 Kontext Dev not loading or generating?
The Space may be starting, busy or temporarily unavailable, or your GPU allowance may be exhausted. Check the message inside the tool. Select Reload if the frame is blank; wait for the provider’s quota reset if your allowance has run out.
Where are my prompts and uploaded images processed?
They are sent to the black-forest-labs/FLUX.1-Kontext-Dev Space on Hugging Face. The host’s processing and retention rules apply. This tool does not process your inputs locally in your browser.
