High quality image editing no longer needs closed models We release FLUX.1 Kontext [dev] - an open weights model for proprietary-level image editing performance. Runs on consumer chips. ✓ Open weights available ✓ Best in-class performance ✓ Self-serve commercial licensing
Purpose-built for image editing: FLUX.1 Kontext [dev] enables iterative editing, excels at character preservation across diverse scenes & allows precise local and global edits. Shares architecture with FLUX.1 [dev] = minimal code changes for inference. Available on @github
Available @huggingface Ready APIs: @fal @replicate @runware @datacrunch_io @togethercompute Comfy Nodes: @ComfyOrg
We collaborate with @NVIDIA_AI_PC and release optimized weights for NVIDIA Blackwell ✓ TensorRT optimized weights ✓ bf16, fp8, fp4 variants ✓ Faster inference, less memory Available @huggingface
Context
Black Forest Labs' June 2025 release of FLUX.1 Kontext dev made its image-editing model available as downloadable weights. Following Kontext's May introduction, the dev release brought iterative editing and character-preservation capabilities to a model the company says can run on consumer hardware.
The release also separates access to weights from permission for commercial deployment. It offers the model under a non-commercial license for research and non-commercial use, alongside a self-service route for purchasing commercial licenses. Developers can therefore evaluate a self-hosted editing workflow while checking the deployment terms relevant to their use.
