Build Hour: GPT-Realtime-2

Build with the next wave of realtime voice AI. In this Build Hour, you’ll learn how to use GPT-Realtime-2, GPT-Realtime-Translate, and GPT-Realtime-Whisper to build low-latency voice agents that can translate live speech, reason across tools, operate apps, and support more natural voice-to-voice and voice-to-action experiences. In this session, Teri Yu (Product) and Erika Kettleson (Solutions Engineering) will cover: • Building with new realtime audio models for translation, streaming speech-to-text, and intelligent voice agents • Using GPT-Realtime-2 capabilities like preambles, 128K context, parallel tool calling, domain understanding, context over turns, and controllable expressiveness • Creating voice-powered workflows for shopping and product analytics dashboards • Customer Spotlight on how Sierra (https://sierra.ai/) is designing production customer experience agents with guardrails, VAD tuning, tracing, redaction, evals, and customer-specific harnesses. 👉 Realtime Voice Blog: https://openai.com/index/advancing-voice-intelligence-with-new-models-in-the-api/ 👉 Voice Agents Docs: https://developers.openai.com/api/docs/guides/voice-agents 👉 Playground: https://platform.openai.com/audio/realtime 👉 Follow along with the code repo: http://github.com/openai/build-hours 👉 Sign up for upcoming live Build Hours: https://webinar.openai.com/buildhours 00:00 Welcome and intro 02:06 Realtime voice models overview 02:26 GPT-Realtime-Translate and GPT-Realtime-Whisper demo 04:36 GPT-Realtime-2: three ways to build with voice AI 05:14 What’s new in GPT-Realtime-2 06:58 Demo: Voice-powered search agent 12:32 Demo: Product analytics dashboard 17:24 What can you build with voice AI? 18:36 Customer spotlight: Sierra 29:56 Q&A 42:05 Resources & Upcoming Build Hours
