Tavus' Griffin video persona: near-call latency, best used as a tireless tutor

sirajraval · x · 2026-10-22

After a week with Tavus' new video persona Griffin, the author calls it the first AI he's talked to face to face that actually holds a conversation — latency close enough to a real call that he stopped noticing it.
The web interface shows a two-way video call with preset interaction prompts (thumbs up, copy me, mid-conversation cut-ins) supporting real-time interruption.
His best use so far: a language tutor that corrects you mid-sentence and never gets tired. More to come.
