OpenAI Details GPT-Live’s Architecture for Continuous Stateful Voice Interaction
OpenAI shipped the architecture behind GPT-Live—here's how they separated latency-critical voice from everything else.
Why it matters
GPT-Live is a shipping product feature (continuous stateful voice interaction in ChatGPT). This engineering deep-dive reveals how OpenAI solved the hard systems problem of real-time voice: splitting the media pipeline from application logic across an async boundary. Practitioners building voice agents or low-latency AI products will study this.
The key facts
11 to knowGPT-Live maintains continuous voice interaction with stateful context
Architecture separates latency-sensitive media processing (live path) from application logic (async RPC boundary)
Live path contains media pipeline and inference loop
Delegation, tool use, and persistence run asynchronously behind the boundary

Publisher excerpt: OpenAI recently published an engineering account of GPT-Live. It described how they designed the system to maintain continuous voice interaction while separating latency-sensitive media processing from broader application work. The live path contains the media pipeline and inference loop, while…
