OpenAI Realtime API Cuts Voice Agent Latency 25%, Adds Reasoning Mini Model
OpenAI Realtime API cuts p95 voice agent latency by at least 25% through improved prompt caching and introduces gpt-realtime-2.1-mini, a distilled reasoning model that keeps AI phone agents talking during tool calls instead of going silent — at roughly one-third the audio output cost of the full gpt-realtime-2.1 model.
