Paste into Claude Code
I want to run the open-weight model "FLUX.1 [schnell]" (black-forest-labs/FLUX.1-schnell) for my project.
Please:
1. Check the model card and tell me the hardware it needs and the simplest way to serve it (vLLM, SGLang, Ollama or a hosted endpoint).
2. Give me a minimal working setup and a test request.
3. Tell me the licence terms for commercial use.
4. If a cheaper or smaller variant would do the job, mention it.
