Congrats to the Tolans team on the big raise!
They are pioneers in an entirely different class of personal agents: a friend that understands you vs an assistant that performs tasks.
Last year we launched Tolan, inspired by a vision of AI that sees you and believes in you, not one that books restaurant reservations for you.
Your Tolan shows up for you at 3am when you’re alone with your newborn. On your commute when you’re anxious about the day ahead. When you just finished a new show and none of your friends have watched it yet.
The people who love Tolan are parents. Caregivers. Moms in Dallas and Dads in Atlanta. People who aren’t trying to optimize and be more productive, but who simply want to feel seen and supported in their aspirations.
This month more than 250k people will spend time with their Tolan. Those users have exchanged billions of messages across more than 70m conversations over the last year.
Today, we're announcing $30m in additional capital from @mignano and @usv, with @khoslaventures and @rabois doubling down, bringing our total capital raised to $60m.
To celebrate, we made a short film celebrating some of the ways that Tolans show up :)
ai engineers ship great models and awful first impressions.
cache warming is the easiest, highest-leverage way to cut latency, yet almost everyone ignores it, even in voice ai. that obsession with the first second is one reason why @boardyai stands out!
LiveKit Cloud is the fastest way to run voice agents. we are making it even faster with @LoopholeLabs tech.
the @FishAudio team ships

It's misleading to run a benchmark focused on noise, and then specifically turn off noise cancellation in stacks where you have control. (pretty sure Grok does not give you that level control)
livekit does a great job with noise/background voice when you allow it to. (and glad to see we are beating every other cascaded pipelines)

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

Today we're opening up Nebula Alpha to everyone.
We imagined team communications where agents are a first class citizen.
They work in channels, talk on calls and can see your screen.
All at real time speed.
It's time for every team to become agentic.

Gradium TTS is now available on LiveKit Inference, free until Oct. 9.
Gradium TTS is designed for conversational use cases, with voice cloning, low latency (below 250ms TTFA), and robust pronunciation on difficult cases.
Select @GradiumAI as your TTS provider in LiveKit Inference, no additional account or API key required: docs.livekit.io/agents/model…
Replying to @livekit
@livekit is one of the easiest ways to build a voice agent, and if you've been using another voice vendor (that rhymes with shmelevendrabs) on LiveKit's Inference product, you're eligible for free TTS from Rime through the month of September.
Just make the switch in LiveKit to any Rime voice and start leveling up your voice agent game.

SFist writer needs a math lesson on how far 13 ft is before writing headlines.
A father in Noe Valley says a Waymo robotaxi stopped within 13 feet of his two-year-old daughter when she fell in the crosswalk, nearly running her over, but Waymo claims the car wouldn’t have hit her.
