One of the coolest parts about building open source software is the amazing stuff that the community creates.
This is a forever thread of the cool stuff built by the LiveKit community 👇

When AI is as smart as a human, we’ll interact with it like we do with each other.
Human interaction is real-time and multimodal:
We use → 👀👂👄
AI uses → 📹 🎙️🔈
Today we're launching a stack for building real-time multimodal AI apps.

To quickly prototype and test your agents, we have the Agents Playground. It’s a client application wired up for streaming voice, video or text to your agent and receiving streams back.

🎻 Orchestration
Conversational agents are stateful, foreground workers and require a different approach to deployment and scale. We built an orchestration system for running thousands of agents in the cloud.

We highlighted how amazing LiveKit is before, but their work is so incredible it bears repeating:
It’s now possible for anyone to build real-time server-side agents that leverage our AI alongside many other models.
A fantastic feat of engineering & we’re proud to be part of it

This is a huge milestone for the project and there's a lot lurking behind the number. A fully end-to-end WebRTC stack requires deep integration between server and clients.

- Speak multiple languages or act as a third-party translator

We wanted KITT to feel human, and the biggest hurdle was latency. We solved it by streaming all the things:
- Convert streaming audio to text in 20ms frames
- Prompt GPT to be concise in its responses
- Sentences are converted to speech in real-time. The results are magical✨

One of the coolest things about KITT is that it works with multiple participants. So KITT could, for example, take notes and create a summary of a long meeting!

Decentralized in the sense that anyone can run their own instances of our media server and auxiliary services, yes. A decentralized version of LiveKit as a cloud-based platform is something we want to/will eventually do.

LiveKit can record videos using our Egress service which can then be uploaded to Instagram using whichever technique you’d like. LiveKit also can stream to Instagram Live using our Egress service via RTMP.
