FP16 .safetensors conversions of MMAudio model checkpoints and dependencies for use with ComfyUI-FFMPEGA.
| File | Description | FP16 Size |
|---|---|---|
mmaudio_large_44k_v2.safetensors | MMAudio large model (44kHz, v2) | 1,966 MB |
v1-44.safetensors | VAE decoder (44kHz) | 583 MB |
synchformer_state_dict.safetensors | Synchformer temporal encoder | 453 MB |
| File | Description | Size |
|---|---|---|
apple_DFN5B-CLIP-ViT-H-14-384_fp16.safetensors | CLIP vision encoder (fp16) | 1,882 MB |
bigvgan_v2_44khz_128band_512x/ | BigVGAN v2 vocoder (44kHz) | ~467 MB |
All models converted from original FP32 sources → FP16 .safetensors (50% size reduction).
All models were downloaded from their original sources and converted by us:
These models are automatically downloaded by the generate_audio skill in ComfyUI-FFMPEGA. No manual setup needed.
