The honest brief
Tavus
Runs on its own render/perception/timing models (Phoenix, Raven, Sparrow) with sub-500ms turn-taking, yet still lets you bring a custom LLM and TTS.
- Live face-to-face AI video
- Own render/perception/timing models
- Plug in custom LLM and TTS
- Developer API and SDKs
- Developer-first, not no-code
- Usage-based cost adds up

Vapi
Solves the hard parts of phone agents — telephony, low-latency turn-taking and barge-in — while leaving STT/LLM/TTS fully pluggable.
- Telephony and interrupts handled
- Pluggable STT + LLM + TTS stack
- Fast to a working phone agent
- Generous developer free tier
- Per-minute costs stack across layers
- Latency depends on chosen models
- Complex configuration surface
- Cloud-only orchestration
