What is Longcat Multi Avatar?
Longcat Multi Avatar is Longcat's AI avatar model that generates scenes with multiple talking characters interacting in the same frame. Unlike single-character models, Multi Avatar supports dialogue between characters with distinct voices, body language, and spatial relationships, producing conversation-style video suitable for podcasts, interviews, and multi-person presentations. The model handles up to multiple characters simultaneously, managing independent lip synchronization, body motion, and gestures for each participant. Characters can interact naturally, with appropriate turn-taking and visual engagement cues that make conversations look organic rather than mechanically composed. Compared to single-character talking head models, Multi Avatar fills a unique niche that few competitors address: multi-person AI-generated dialogue video. Against compositing multiple single-character videos together, the native multi-character approach produces more natural interaction. Complex scenes with many characters or fast dialogue may occasionally show artifacts. Best suited for multi-character dialogue, conversation videos, and multi-person presentation content where natural interaction between AI-generated characters is required. Available on FairStack at infrastructure cost plus a 20% platform fee.
