Comfy-Org Rescues Stable Diffusion 1.5 With 1.5M-Download Mirror
Comfy-Org has published a repackaged archive of Stable Diffusion v1.5 on Hugging Face, preserving the original weights after RunwayML pulled its page.
- Comfy-Org published an archival re-upload of Stable Diffusion v1.5 at huggingface.co/Comfy-Org/stable-diffusion-1.5.
- The upload exists because RunwayML took down the original SD v1.5 model page.
- Includes a hash-identical copy of the original weights plus an FP16 conversion with added metadata.
- Files are packaged as single-file safetensors for drop-in use with ComfyUI checkpoints folder.
- Repo has over 1.5 million downloads under the CreativeML OpenRAIL-M license.
- Intended for legacy testing and reproducibility, not as a current-generation recommendation.
Comfy-Org has republished Stable Diffusion 1.5 in a public SD 1.5 mirror on Hugging Face. The repository provides single-file safetensors checkpoints that load directly in ComfyUI, has recorded more than 1.5 million downloads, and lists the CreativeML OpenRAIL-M license.
RunwayML released Stable Diffusion 1.5 in 2022 and later removed its original repository, breaking a common source for the model’s weights. Comfy-Org created the mirror to preserve access for legacy workflows, research reproduction, and tools built around the SD 1.5 architecture. Weight provenance matters because conversions and fine-tunes can change generated results even when filenames look similar.
A Small Archive With Three Choices
The repository contains two versions of the base checkpoint and one community fine-tune:
| File | Contents | Best fit |
|---|---|---|
v1-5-pruned-emaonly.safetensors |
The original RunwayML upload, with the same file hash according to the repository’s model card. | Reproduction work that requires the original artifact. |
v1-5-pruned-emaonly-fp16.safetensors |
A half-precision conversion with an added metadata header. |
