About

What FLUX.1-dev is

This is a direct GGUF conversion of black-forest-labs/FLUX.1-dev As this is a quantized model not a finetune, all the same restrictions/original license terms still apply. The model files can be used with the ComfyUI-GGUF custom node. Place model files in ComfyUI/models/unet - see the GitHub readme for further install instructions. Please refer to this chart for a basic overview of quantization types.

Using it via the API

Call it like any OpenAI endpoint

Once AxForge deploys city96-flux-1-dev for you, it answers on the OpenAI-compatible API — the same base URL and keys as every other model. (city96-flux-1-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-1-dev","prompt":"a red bicycle","size":"1024x1024"}'
