When to choose which
- Documented BFL ecosystem (ComfyUI, Diffusers, TensorRT-LLM): FLUX 3 Image Klein — BFL ships reference code and docs; HF blog covers Diffusers. Qwen turbo docs not in our extract.
- Fewer denoising steps (official examples): Qwen-Image-2.1-Turbo — Qwen turbo examples use 8 steps; FLUX distilled is 16-step (no CFG). Speed on your GPU untested.
- <$5M revenue commercial use with defined license: FLUX 3 Image Klein — FLUX Kommunity License allows commercial output generation for Qualifying Users. Qwen card says "other"; read terms.

Can I run both locally?
Both publish weights on Hugging Face. BFL docs say FLUX Klein fits RTX 3090+. Qwen-Image-2.1-Turbo VRAM is not in our extract. Hardware is not independently tested.
Which license is clearer for commercial use?
FLUX Kommunity License v.1.0 is documented (non-commercial + <$5M commercial output generation for Qualifying Users). Qwen card says "other"; read the attached terms. Not legal advice.
