🚀 We're excited to release LightVAE! The first framework to accelerate both video VAE encoding and decoding.
⚡ Up to 4.2× faster VAE decoding! MiniMax-H3 reference-image encoding is also up to 2.68× faster.
✨ Supports Wan2.1, Wan2.2, and MiniMax-H3, with high-fidelity and lightweight variants that largely preserve generation quality.
🧩 Temporal low-rank compression, block pruning, and teacher-guided quality recovery. Code, model weights, and ComfyUI workflows are all open source!
🙌 Check it out and give it a try—we'd love to hear your feedback!
