Safetensors metadata reports 11,901,408,320 parameters, and the hub lists diffusers support with safetensors and FluxKontextPipeline tags.
Guidance-distilled training
According to the model card, the model was trained using guidance distillation, making FLUX.1 Kontext [dev] more efficient.
Documented Diffusers and safety path
According to the model card, the model works with Diffusers FluxKontextPipeline and ComfyUI, and ships with an integrity checker to run after generation.
Use cases in the source record
- Instruction-based editing of existing images using the publisher-documented text-instruction workflow and Diffusers pipeline.
- ComfyUI or Diffusers-based image-editing trials, plus API-based use through the endpoints named in the model card.
Limitations and unknowns
- No Ethen-measured evaluation results were extracted from this record.
- No context-window value was extracted.
- Provider state is historical snapshot data and should be refreshed before being presented as current.
- Capability, training, and safety claims are publisher model-card statements and were not independently verified by Ethen.
