Deep Architectural Overview
GPT-Live 1 can listen and speak simultaneously, eliminating unnatural turn-taking delays. It delegates complex calculations or search queries to backend agent models without interrupting conversational speech flow.
Strengths & Considerations
Core Strengths
- Full-duplex audio (speaks and listens concurrently)
- Smooth interruption handling with 180ms latency
- Billed per second at $0.05/minute
Known Limitations
- Audio session only; delegator model calls billed separately
