About
Black Forest Labs builds FLUX image models with flow matching, a generative training method. FLUX.1 launched in August 2024 and FLUX.2 in November 2025, and FLUX 3 is the newest generation; some versions are released as open weights and others only as hosted models.
- FLUX.1 and FLUX 1.1: Text-to-image; open-weight FLUX.1 Schnell and Dev, plus the hosted FLUX 1.1 Pro and the 4 MP FLUX 1.1 Pro Ultra.
- FLUX.1 Kontext: Instruction-based image editing in Kontext Pro and Kontext Max: change part of an image by describing the edit in plain words.
- FLUX.2 Pro: Text-to-image and image editing from the second FLUX generation.
- FLUX 3: Text-to-image and image editing from the newest FLUX generation, from quick 512px square drafts up to 4K output.
Build with the API
One MuseSpan API key calls every Black Forest Labs model on this page: copy a model ID and send it as the model field of your request.
