Meituan open-sources LongCat Avatar 1.5 for multi-speaker talking videos
Meituan just open-sourced LongCat-Video-Avatar 1.5, a model that turns a single portrait and audio track into realistic talking video. It handles anime and realistic styles, supports multi-person conversations, and cuts diffusion down to 8 steps for a 15x speedup. The 16GB INT8 weights and code are now available on GitHub and Hugging Face.
