What happened
Freiburg-based Black Forest Labs released the open weights of FLUX 3 Image Klein on 15 October 2026. The 5.6-billion-parameter model generates and edits images, takes up to 10 reference images, and its INT8 build runs on a GeForce RTX card with 8 GB of memory.
The weights sit on Hugging Face under the FLUX Kommunity License v1.0, issued by Black Forest Labs Inc. Commercial use of outputs is limited to "Qualifying Users": anyone whose gross annualised revenue, with affiliates, is below US$5,000,000.
Why it matters
For a student, freelancer or small studio, the licence allows paid use of storyboards, keyframes and stills made locally. Section 2(e) adds two duties: filter outputs or review them for unlawful or infringing content before distribution, and disclose that an output was AI-generated or modified where the law requires it. Section 4 prohibits uses that breach the EU AI Act.
Downloading needs only acceptance of the licence. Using the pictures in paid work carries those conditions.
Still open
The model card says the commercial exception is not blanket permission for commercial fine-tuning or distribution, a limit for makers training character models for clients. Self-hosted commercial tiers on bfl.ai/licensing list no prices. As of 22 October 2026.
For your film
Before using Klein images in paid work, check your revenue against the threshold and note how you filter or review outputs before distribution.
