FLUX.1 Kontext [dev] is an image editing model from Black Forest Labs, released as the developer version of FLUX.1 Kontext [pro] in the FLUX.1 Kontext family. Its launch headline is open weights for image editing: the maker says it is the first capable generative image editing model available as open weights, delivering proprietary-level editing performance on consumer hardware. The model focuses on editing tasks, supporting iterative text-guided edits, consistent characters across scenes and environments, and precise local or global changes.
