FLUX.1 Kontext [dev]

by Black Forest Labs

FLUX.1 Kontext [dev] brings Black Forest Labs' instruction-based image editing to open weights, released in June 2025 as a 12 billion parameter diffusion transformer guidance-distilled from Kontext [pro]. Rather than generating from scratch, it takes a source image together with a plain-language instruction and returns an edited version, handling both precise local changes and broader global transformations. The model is built for iterative editing, preserving characters, objects, and style across successive edit steps with minimal visual drift. Its size lets it run on accessible hardware, which suits teams building repeatable programmatic editing pipelines, product image touch-ups, and multi-step creative workflows around an open model.
