Our first family of models powers lifelike avatars that interact with users in real time, enabling AI agents and applications to go beyond text and voice with just a few lines of code. State-of-the-art realism with ultra-low latency at scale. Keyframe Labs is a Y Combinator company (Spring 2026). YC-listed status: Active.
