  • Hunyuan3D 2.0
• Asynchronous Queue system
• Many optimizations: Only re-executes the parts of the workflow that changes between executions.
• Smart memory management: can automatically run large models on GPUs with as low as 1GB vram with smart offloading.
• Works even if you don't have a GPU with: --cpu (slow)
• Can load ckpt and safetensors: All in one checkpoints or standalone diffusion models, VAEs and CLIP models.
• Safe loading of ckpt, pt, pth, etc.. files.
• Embeddings/Textual inversion
• Loras (regular, locon and loha)
• Hypernetworks
• Loading full workflows (with seeds) from generated PNG, WebP and FLAC files.
• Saving/Loading workflows as Json files.
• Nodes interface can be used to create complex workflows like one for Hires fix or much more advanced ones.
• Area Composition
• Inpainting with both regular and inpainting models.
• ControlNet and T2I-Adapter
• Upscale Models (ESRGAN, ESRGAN variants, SwinIR, Swin2SR, etc...)
• GLIGEN
• Model Merging
• LCM models and Loras
• Latent previews with TAESD
• Works fully offline: core will never download anything unless you want to.
• Optional API nodes to use paid models from external providers through the online Comfy API disable with: --disable-api-nodes
• Config file to set the search paths for models.

Release Process

ComfyUI follows a weekly release cycle targeting Monday but this regularly changes because of model releases or large changes to the codebase. There are three interconnected repositories:

1. ComfyUI Core

   • Releases a new stable version (e.g., v0.7.0) roughly every week.
   • Starting from v0.4.0 patch versions will be used for fixes backported onto the current stable release.
   • Minor versions will be used for releases off the master branch.
   • Patch versions may still be used for releases on the master branch in cases where a backport would not make sense.
   • Commits outside of the stable release tags may be very unstable and break many custom nodes.
   • Serves as the foundation for the desktop release

2. ComfyUI Desktop

   • Builds a new release using the latest stable core version

3. ComfyUI Frontend

   • Weekly frontend updates are merged into the core repository
   • Features are frozen for the upcoming core release
   • Development continues for the next release cycle
