Tavus

Tavus is a developer-first AI research lab and platform for building hyper-realistic AI humans that can hold face-to-face, real-time video conversations inside B2B applications.

Key capabilities include:

• Conversational Video Interface (CVI) for low-latency, real-time video agents (reported sub-600ms response times) with natural turn-taking and pacing.
• Replica and video generation APIs to create videos from text, plus voice and face cloning from minimal training data (minutes of audio/video).
• Lip-Sync and Dubbing APIs to match facial motion to audio and translate video across 30+ languages.
• Control tools for production use, including knowledge base integration, memory, guardrails, objective-setting, and fast RAG (reported 30ms retrieval).

Pricing: Freemium; Free tier ($0/mo) includes 25 minutes of conversational video and white-labeled APIs. Paid plans start at $59/month (Starter) and $397/month (Growth), both of which allow for additional pay-as-you-go usage. Enterprise pricing is custom (typically starting around $12,000/year).

What makes it notable is its model stack purpose-built for human-like video interaction: Phoenix for photorealistic rendering and micro-expressions, Raven for real-time emotion and body-language interpretation, and Sparrow for conversation timing, along with support for API and React-based integrations.
