+- FLUX.1 ControlNet training is supported. PR [#1813](https://github.com/kohya-ss/sd-scripts/pull/1813). Thanks to minux302!  See PR and [here](#flux1-controlnet-training) for details.
+  - Not fully tested. Feedback is welcome.
+  - 80GB VRAM is required for 1024x1024 resolution, and 48GB VRAM is required for 512x512 resolution.
+  - Currently, it only works in Linux environment (or Windows WSL2) because DeepSpeed is required.
+  - Multi-GPU training is not tested.
