FLUX.2

by Black Forest Labs: https://bfl.ai

Documentation for our API can be found here: docs.bfl.ai.

This repo contains minimal inference code to run image generation & editing with our FLUX.2 open-weight models.

`FLUX.2 [dev]`

FLUX.2 [dev] is a 32B parameter flow matching transformer model capable of generating and editing (multiple) images. The model is released under the FLUX.2-dev Non-Commercial License and can be found here.

Note that the below script for FLUX.2 [dev] needs considerable amount of VRAM (H100-equivalent GPU). We partnered with Hugging Face to make quantized versions that run on consumer hardware; below you can find instructions on how to run it on a RTX 4090 with a remote text encoder, for other quantization sizes and combinations, check the diffusers quantization guide here.
