We’re opening a research preview of Claude Duet, a new app where Claude works as a proactive agent. It comes to you with what needs your attention, completes tasks you ask of it, keeps working when you step away, and checks with you before it acts on your behalf.

Voice agents get built three ways: cascaded (STT, LLM, TTS), turn-based speech-to-speech, and full-duplex, where the model listens and talks at the same time. All three now run on LiveKit Inference: GPT-Live and GPT Realtime from @OpenAI, @grok Voice Think Fast from @xai, and Gemini Live from @GoogleDeepMind. One LiveKit Cloud key, one bill.

This is a great use case for Jev + LiveKit!
A demo of a practical use case for Jev: routing customer inquiries on a live call center line Fun voice AI project built with @livekit It's really incredible to see how quickly Jev can act on a live call and bring in real-time AI judgment on everything the caller says

Gemini 3.8 Flash-Lite TTS is nice to talk to. What do you think?
Is your voice agent moody? It should be! With Gemini 3.8 Flash-Lite TTS, you can direct its mood or let the agent decide for itself. Cheerful, furious, wistful, apologetic, it nails all of them and sounds great. Give it a try on LiveKit: livek.it/obFIyE5
