Flat all-in Omni pricing, per-second AI billing, managed Agents, and Trace on the same stack.
Retell AI
Public pricing and market estimates as of June 2026; verify before relying on procurement numbers.
Best fit
Teams that value predictable cost and fewer component decisions.
Retell can be attractive if you want to tune each underlying component separately.
Why switch to PyAI
- Predictable all-in rate
- Lower vendor-management overhead
- ~431 ms median Omni turn-taking receipt
- Trace compliance package
- Free Hear minutes for migration and testing
Where voice AI spend leaks
Costs buyers often miss
- Platform fees or seats that must be paid before usage creates value
- Pass-through STT, realtime model, TTS, telephony, and orchestration bills that are hard to forecast
- Credit or character pricing that hides the cost of long calls and long-form audio
- Manual QA, compliance review, and call summaries that only happen after the expensive mistake
How PyAI helps you prove the switch
PyAI keeps testing cheap and migration practical: free credits, OpenAI-compatible surfaces where supported, transparent minute pricing, and production add-ons for QA, compliance, summaries, and grounding.
