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.

@thorwebdev @NanoBanana congrats!! 🥂

[Jesse Hall @codeSTACKr]

@chrissev you look like you’re about to drop that mic

[Jesse Hall @codeSTACKr]

@joelhooks notes?

[LiveKit @livekit]

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.

@chrissev @livekit happy to help!

i keep seeing all of these amazing hype reels that people are saying opus 5.5 created with a single prompt.

one shot, yeah right.. liars!! so i tried it.

prompt: "make a dynamic 15-second motion graphics video that shows what an incredible motion designer you are, like it's your showreel for a resume. go all out"

@chenzhangreal my post was a bit snarky. the video above was the first take with that exact prompt. i was very surprised.

This is a great use case for Jev + LiveKit!

[rahat @Rahatcodes]

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

[Jesse Hall @codeSTACKr]

@Rahatcodes Perfect use case - great job!

[Jesse Hall @codeSTACKr]

@saltnburnem who is that??

Gemini 3.8 Flash-Lite TTS is nice to talk to.
What do you think?

[Jesse Hall @codeSTACKr]

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: https://t.co/4eE69pmR3Y
