ace-gguf

gguf quantized ace-step-v1-3.5b

• base model from ace-step
• full set gguf (model+encoder+vae) works right away

setup (once)

• drag ace-step to > ./ComfyUI/models/diffusion_models
• drag umt5-base to > ./ComfyUI/models/text_encoders
• drag pig to > ./ComfyUI/models/vae

workflow

• drag json or demo audio below to browser for workflow

review

• note: as need to keep some key tensors (in f32 status) to make it works; file size might not decrease that much; but load faster than safetensors checkpoint in general (no last minute bottle neck problem)
• rebuilding umt5-base tokenizer logic applied successfully; upgrade your node to the latest version for umt5-base encoder support; hence, safetensors checkpoint is no longer needed (removed here; if you want it still, you could get it from comfyui-org)
• get more umt5-base encoder here

bonus: fp8/16/32 scaled stable-audio-open-1.0 with gguf quantized t5_base encoder

• base model from stabilityai
• note: this is a different model; don't mix it up; also powerful and lite weight

setup (once)

• drag t5-base to > ./ComfyUI/models/text_encoders
• drag safetensors to > ./ComfyUI/models/checkpoints
• drag pig to > ./ComfyUI/models/vae

review

• note: the safetensors checkpoint in this repo is an extracted version; only contains model and condition switch tensors (extremely lite weighted); no clip and vae inside; should use it along with separate clip (text encoder) and vae
• opt to get fp8/16/32 scaled checkpoint with model and vae embedded here
• get more t5-base encoder here
