- Bolna Launches OpenAI Realtime Voice AI Models in India for Enterprise Voice Agents ↗
Bolna says it was the only official launch partner from India for OpenAI’s new realtime voice models and that it tested GPT-Realtime-Whisper and GPT-Realtime-2 against Indian-language, code-mixed, latency, tool-calling, and cost constraints. The post says the transcription model performed well in Hindi, Tamil, and Telugu tests, while the reasoning model improved interruption handling, parallel tool calling, and recovery behavior, though some code-mixed cases and cloud-only limitations remain challenging.
