EchoMimicV3-MLX

EchoMimicV3 MLX checkpoint

This repository contains the pinned, native-MLX checkpoint layout used by the AI2Apps ai2apps.model.echomimic-v3-mlx Model Worker on Apple Silicon.

The checkpoint combines:

• EchoMimicV3 Flash transformer from BadToBest/EchoMimicV3 at 311e176905a8c4c24b240b530488fe636ce4d249;
• Wan-Fun VAE, UMT5 encoder export, and OpenCLIP encoder export from alibaba-pai/Wan2.1-Fun-V1.1-1.3B-InP at fc913c34361f4ec879e2f9c78b4f11ae50a937d1;
• Chinese Wav2Vec2 Base from TencentGameMate/chinese-wav2vec2-base at cb511a6498884e41e35686f4b4d6c5188e181773;
• UMT5 tokenizer metadata derived from google/umt5-xxl.

The .safetensors VAE, UMT5, and OpenCLIP files are deterministic, tensor-only conversions of their pinned PyTorch source checkpoints. See ai2apps-checkpoint.json for exact file sizes, SHA-256 digests, and source revisions.

This repository contains model weights only. Use them through a compatible EchoMimicV3 implementation and follow the upstream projects' documentation.
