}Evidence claims
- [upstream_claim] 12B-parameter rectified flow transformer for editing existing images with text instructions; page says it can keep a character, style or object consistent across multiple successive edits. source
- [sourced_fact] Diffusers usage via FluxKontextPipeline with bfloat16 and guidance_scale 2.5; install diffusers from main per the card; gated behind FluxDev Non-Commercial License and AUP acceptance. source
- [sourced_fact] Card describes safety measures (NSFW training-data filtering, CSAM/NCII mitigation) and recommends an integrity checker after generation. source
- [sourced_fact] BFL prompting reference tips for Kontext: describe only what should change, quote text edits, state what must stay the same (e.g. facial features, hairstyle), use specific action verbs. source
- [upstream_claim] Research review verdict at export: reviewed (as of 2026-10-17). Recorded by the research pipeline, not a hub review outcome; evidence.review stays unreviewed until an independent reviewer records one.

| model_weights | FLUX.1-dev-Non-Commercial-License | restricted | restricted | restricted | prohibited | Card names the FLUX.1 [dev] Non-Commercial License and states outputs may be used for personal, scientific and commercial purposes. The license text read was the FLUX.1-dev LICENSE.md (shared by the dev-tier family); a Kontext-specific file was not separately read. Output-for-competing-model-training prohibition per that text. |
