| | # OpenAI Whisper Models |
| |
|
| | Mirror of [OpenAI Whisper](https://github.com/openai/whisper) model weights in **safetensors** format, hosted by [AEmotionStudio](https://github.com/AEmotionStudio) for use with [ComfyUI-FFMPEGA](https://github.com/AEmotionStudio/ComfyUI-FFMPEGA). |
| |

|
| | **Original source:** [OpenAI Whisper](https://github.com/openai/whisper) (Azure CDN) |
| |
|
| | ## 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. |
