Using it via the API
Once AxForge deploys flux-2-dev-bnb for you, it answers on the OpenAI-compatible API — the same base URL and keys as every other model. (flux-2-dev-bnb below is illustrative; you get the exact model name on deployment.)
$ curl -sS https://api.axforge.ai/v1/images/generations \
-H "Authorization: Bearer $AXFORGE_API_KEY" \
-H "Content-Type: application/json" \
-d '{"model":"flux-2-dev-bnb","prompt":"a red bicycle","size":"1024x1024"}'

Licence
The weights are open but its licence needs a commercial agreement for business use. AxForge can arrange that licence and host the model for you — you pay AxForge, we settle with the model’s maker. Ask us for a quote. Read the licence ↗
