Format

Models are stored in .safetensors format for security. The dims configuration metadata is preserved in each file's safetensors header. ComfyUI-FFMPEGA automatically handles the conversion to .pt format locally when downloading from this mirror.

Usage

These models are automatically downloaded by ComfyUI-FFMPEGA when audio transcription or subtitle generation is used. No manual setup is required if allow_model_downloads is enabled on the FFMPEG Agent node.

Manual Installation

1. Download the desired .safetensors file from this repo
2. Convert to .pt or place in ComfyUI/models/whisper/
3. FFMPEGA will detect the local file and skip downloading

Why This Mirror?

This is a first-party mirror maintained by AEmotionStudio to ensure supply chain resilience. If OpenAI's CDN becomes unavailable, FFMPEGA will still be able to download models from this mirror.
