Had the chance to validate Ava Zero early, and it delivers. The thing most voice agent builders miss is real-world conditions: background noise, crosstalk, messy audio. Ava Zero handles all of it without giving up speed, and inference stays lightning fast. Kudos 🚀
Introducing Avartha. We're building the infrastructure to bring frontier-grade intelligence to real-time applications. Our first release, Ava Zero, is a voice agent entirely running open models using our inference infrastructure and ranks #1 on Sierra's tau-voice benchmark with highest task completion rate and generation quality and just costs $2.5 per hour. Open models are now at the frontier of voice AI.
