Chroma1 Radiance DF11

--- license: apache-2.0 language: - en pipeline_tag: text-to-image tags: - comfyui - diffusion-single-file base_model: - lodestones/Chroma1-Radiance base_model_relation: quantized --- #### Update: I just uploaded the latest x0 version. Because the file has no version number to distinguish it, I appended the SHA256 hash to the filename. # Note: The "expanded" version simply has some components (basically the extra tensors that are specific to Radiance) left uncompressed. Both versions give *identical outputs*, just that I find the non-expanded version to tank in speed with tiling enabled, which for some setups might not be worth the ~0.4GB size decrease. For more information (including how to compress models yourself), check out https://huggingface.co/DFloat11 and https://github.com/LeanModels/DFloat11 Feel free to request for other models for compression as well, although compressing models that do not use the Flux architecture might be slightly tricky for me. ### How to Use #### ComfyUI Install my own fork of the DF11 ComfyUI custom node: https://github.com/mingyi456/ComfyUI-DFloat11-Extended. After installing the DF11 custom node, use the provided workflow [json](Chroma1-Radiance-DF11-workflow.json), or simply replace the "Load Diffusion Model" node of an existing Chroma workflow with the "DFloat11 Model Loader" node. If you run into any issues, feel free to leave a comment. The workflow is also embedded in the below [png](Chroma1-Radiance-DF11-workflow.png) image.  #### `diffusers` As far as I know, this model architecture is currently not yet supported in `diffusers`. ### Compression Details This is the `pattern_dict` for compressing Chroma-based models in ComfyUI: ```python pattern_dict_comfyui = { r"distilled_guidance_layer\.layers\.\d+": ( "in_layer", "out_layer" ), r"double_blocks\.\d+": ( "img_attn.qkv", "img_attn.proj", "img_mlp.0", "img_mlp.2", "txt_attn.qkv", "txt_attn.proj", "txt_mlp.0", "txt_mlp.2", ), r"single_blocks\.\d+": ( "linear1", "linear2", ), r"nerf_blocks\.\d+": ( "param_generator", ) } ```
