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: https://huggingface.co/black-forest-labs/FLUX.1-Kontext-dev
- [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: https://huggingface.co/black-forest-labs/FLUX.1-Kontext-dev
- [sourced_fact] Card describes safety measures (NSFW training-data filtering, CSAM/NCII mitigation) and recommends an integrity checker after generation. · source: https://huggingface.co/black-forest-labs/FLUX.1-Kontext-dev
- [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: https://docs.bfl.ml/guides/prompting_unified_reference
- [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.

Rights:
- model_weights: license=FLUX.1-dev-Non-Commercial-License hosting=restricted redistribution=restricted modification=restricted training=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. · evidence: https://huggingface.co/black-forest-labs/FLUX.1-Kontext-dev, https://huggingface.co/black-forest-labs/FLUX.1-dev/blob/main/LICENSE.md
