Vapi opens private beta and public waitlist for GPT-Live speech-to-speech model

Vapi has opened a limited private beta for GPT-Live, OpenAI's next-generation full-duplex speech-to-speech model, alongside a public waitlist for early access. GPT-Live replaces the modular speech-to-text, LLM and voice pipeline by handling all three in one model, cutting turn latency and preserving tone and emphasis. Beta teams run it on the same Vapi stack as existing modular agents, and modular pipelines remain supported.
