Run LongCat-Avatar on Your Own Machine

The honest, no-hype guide to Meituan's open-source LongCat-Video-Avatar 1.5 — turn one photo + one audio clip into a lip-synced talking video. What it actually is (a 13.6B MIT-licensed video model, not just an avatar tool), a 5-step setup to run it on your own GPU (grab the weights, hardware + INT8 check, install the Whisper-Large-v3 stack, run inference with audio CFG 3-5 at 480p/720p), and an honest expectations page: where it shines, where it falls short, and why quality lands next to Wan 2.2 — excellent and free, not a SOTA knockout.
