Viewing profile — russ

Hey HN, it’s Russ - cofounder of LiveKit. An open source stack for building realtime AI applications. We’re sharing our first homegrown AI model for turn detection. Here’s a live d…

Yeah, that would be really handy too.

This is very cool! I’ve wanted something like CodeMic for a long time. Back when I was at Twitter, we used Review Board for code reviews (this was in 2009, before GH was a thing fo…

You got it! Hope you have some fun with it. :)

Haven’t played Codenames in a long while, but made this 8 years ago to play with family and friends on TVs. Right in time for the holidays! demo: https://dsa.github.io code: https:…

Haha yup, I’m that Russ. Really appreciate your kind words. I’ll shoot you an email and let’s chat!

This is super cool. One neat idea: when I'm in offline mode, I can clone my voice, provide some context data/sources, and have my AI clone answer calls for me. It can give me a sum…

Heh, actually I'm pretty sure I've come across your X profile before. :) You're definitely in a small minority of folks with a deep(er) understanding of WebRTC.

You really don’t need to know about WebRTC at all when you use LiveKit. That’s largely thanks to the SDKs abstracting away all the complexity. Having good SDKs that work across eve…

Doesn’t sound right. I’d love to dig into this some more. Would you mind shooting me a DM on X? @dsa

Field CTO — hi @Sean-Der :wave: Fractional CTO sounds like a disaster lol

Which components feel ad hoc? In most real applications, the agent has additional logic (function calling, RAG, etc) than simply relaying a stream to the model server. In those cas…

There’s Ultravox as well (from one of the creators of WebRTC): https://github.com/fixie-ai/ultravox Their model builds a speech-to-speech layer into Llama. Last I checked they have…

There’s a ton of complexity under the “relatively simple use case” when you get to a global, 200M+ user scale.

50% human speaking at $0.06/minute of tokens 50% AI speaking at $0.24/minute of tokens we (LiveKit Cloud) charge ~$0.0005/minute for each participant (in this case there would be 2…

We had our playground ( https://playground.livekit.io ) up for a few days using our key. Def racked up a $$$$ bill!

I had no idea! <3 Thank you for sharing this, made my weekend.

It's using the same model/engine. I don't have knowledge of the internals, but a different subsystem/set of dedicated resources though for API traffic versus first-party apps. One …

Hey HN, we've been working with OpenAI for the past few months on the new Realtime API. The goal is to give everyone access to the same stack that underpins Advanced Voice in the C…

It’s insanely fast. Here’s an AI voice assistant I built that uses it: https://cerebras.vercel.app

Here’s an AI voice assistant we built this weekend that uses it: https://x.com/dsa/status/1828481132108873979?s=46&t=uB6padbn...

LiveKit Agents, which OpenAI uses in voice mode is also open source: https://github.com/livekit/agents

But we don't handle interruptions yet, that's some cool stuff @yanyan_evie!
