About Keyframe Labs

Keyframe Labs builds human foundation models and sells the first family of them as an API for real-time interactive avatars. The pitch is to developers who already have an AI agent working in text or voice and want to give it a face without taking on a rendering pipeline: a few lines of code, a stock avatar, and the LLM and voice provider of your choosing, which the platform deliberately leaves open rather than bundling. The properties it competes on are the ones that decide whether a video avatar is usable in a live product rather than a demo reel — photorealism, emotional expression, and latency low enough that turn-taking does not feel broken. Setup is documented as roughly five minutes, call length is uncapped, and concurrency scales into the thousands on higher tiers. Billing is a credit system layered over minutes, which is worth understanding before committing: each plan includes a monthly minute allowance, one minute of conversation on the persona-1.5-live model costs six credits, and overage minutes run from $0.06. That makes the free tier a genuine evaluation surface — thirty minutes a month, five-minute conversations, one concurrent session — rather than a teaser. Custom and image-to-avatar generation, zero data retention, EU or US data residency, elevated concurrency and custom SLAs sit on the enterprise tier, which is the tell that the paid ladder is aimed at products going to production rather than one-off experiments.
