What is Longcat Single Avatar?
Longcat Single Avatar is Longcat's AI avatar model that generates single-character talking head video with natural body motion and gestures beyond basic lip synchronization. The model produces presenter-style video where the character's body moves naturally, including hand gestures, posture shifts, and subtle movements that make the presentation feel more engaging and human. The model goes beyond basic lip sync by generating full upper-body motion that supports the speech content. Head nods, hand gestures, and body language add visual engagement that static talking heads lack. This fuller range of motion makes the output more suitable for professional presentations and content where body language matters. Compared to lip-sync-only models that animate just the mouth area, Longcat Single Avatar produces more engaging content through body motion. Against multi-character avatar models, it focuses on delivering the best single-character experience. The per-second pricing scales with output duration, keeping costs proportional. Best suited for presenter videos, professional avatar content, and single-character talking head production where natural body motion and gestures enhance viewer engagement. Available on FairStack at infrastructure cost plus a 20% platform fee.
