Model reference · open weights
FLUX.2-dev is an open-weight image model from city96, listed in the AxForge catalogue. AxForge can bring it up on EU-owned hardware for you on request — with the licence handled where one is required.
About
This is a direct GGUF conversion of black-forest-labs/FLUX.2-dev. The model files can be used in ComfyUI with the ComfyUI-GGUF custom node. Place the required model(s) in the following folders: Example outputs - sample size of 1, not strictly representative Notes [!NOTE] As with Qwen-Image, Q5KM, Q4KM, Q3KM, Q3KS and Q2K have some extra logic as to which blocks to keep in high precision. The logic is partially based on guesswork, trial & error, and the graph found in the readme for Freepik/flux.1-lite-8B (which in turn quotes this blog by Ostris) As this is a quantized model not a finetune, all the same restrictions/original license terms still apply.

Using it via the API
Once AxForge deploys city96-flux-2-dev for you, it answers on the OpenAI-compatible API — the same base URL and keys as every other model. (city96-flux-2-dev 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":"city96-flux-2-dev","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 ↗
