The team at @OpenAI shipped an interesting update!
GPT-Reatime-1.5 is OpenAI's flagship model audio model for voice agents & customer support.
Voice workflows just got stronger with gpt-realtime-1.5 in the Realtime API. The model offers more reliable instruction following, tool calling, and multilingual accuracy.
A +5% lift on Big Bench Audio and double-digit gains in alphanumeric transcription are not cosmetic improvements, they directly impact real-world reliability in production voice systems.
What stands out most from early partner results @Genspark @Sendbird:
66% human connection rate (up from 43.7%)
97.9% perfect score across scored conversations
Problem case rate cut in half
Stronger dialog completion
Those numbers point to better instruction adherence, cleaner tool calls, and more stable turn-taking, exactly what voice agents have historically struggled with.
Low latency + stronger interruption handling + improved multilingual accuracy makes this feel less like a demo upgrade and more like infrastructure maturing for enterprise use.
Excited to see what builders ship on top of this.
