Vomyra vs OpenAI GPT Realtime (DIY)

Building on the GPT Realtime API directly gives you full control, but it is a real engineering project: WebSocket streaming, audio format conversion, telephony integration and reconnection handling before your first production call. Vomyra already runs GPT Realtime in production — you deploy an agent on an Indian number in minutes and can switch to Nova 2 Sonic or another model from a dropdown.

FAQ

Vomyra vs OpenAI GPT Realtime (DIY): common questions

Should I build on the OpenAI Realtime API or use Vomyra?

If you want maximum control and have engineers, building directly works. If you want GPT Realtime in production on Indian phone numbers this week, Vomyra already runs it — you skip the WebSocket streaming, audio conversion and telephony integration and configure an agent from a dashboard.

Does Vomyra use GPT Realtime under the hood?

Yes. GPT Realtime runs in production on Vomyra today, and you can switch to AWS Nova 2 Sonic, Azure Voice Live or another frontier model from a dropdown to compare them on the same calls.

How does pricing compare?

Building directly means paying OpenAI API usage in USD plus your own telephony and infrastructure. Vomyra bills per second in INR — the model, the telephony orchestration and Indian numbers in one rate — with unlimited plans available.
