If the last 24 hours has taught us anything, it's the value of open source.
openpilot is to FSD as Kimi is to Fable. Open source AI lags behind now, but who are you betting on long term?

Getting mad about Elon becoming a trillionaire is literally a skill issue. Git gud.
The size of Tesla never stopped @comma_ai or @EdisonMotorsLtd from competing.

From concepts to shelves: comma four
@robbederks tells the story of how we built comma four, from RF struggles to your windshield

I tied for #1 on the @comma_ai Controls Challenge leaderboard.
The task: steer a car across 5,000 driving segments.
I wrote up the full build process, failed approaches, optimization strategy, and noise-floor analysis:

Ok this challenge is too easy for the LLMs now.
We're hiring for 3 positions on the hardware team.
Just email work@comma with pics of cool things you've built.
On site in San Diego. Come play with our machines!
✨ New HW challenge prize
We designed a simple harness testing PCB and wrote some firmware for it. Unfortunately, this board was designed on a Monday morning.
Find as many bugs as you can. First submission with a score >21 gets $1000.

When a cell phone has better ADAS than Rivian
Hopefully Rivian can release some of what they’ve been working on to the public but for now… @comma_ai 💪

Want to work on a datacenter with 1k GPUs?
I'm hiring people to write code for our small 500kw cluster (~3MW in couple years). You'll work with things like SLURM, PyTorch, NFS, Linux, miniray, minikeyvalue.

Found the curviest, twistiest backroad around me to test angle-based steering on the Rivian with the new Extreme Harness Kit from Xnor. No lane lines, no mercy. 😅
Shoutout to @comma_ai for handling it like a champ. Harnesses kits are shipping to customers now!

Supervised learning is kinda lame. I've always found RL the cool part of ML. It's what can make machines feel truly alive!
So far RL has had little practical use in robotics, but not anymore! The next version of openpilot's driving model will be fully RL trained.

This map shows something most people don’t realize:
Open-source autonomy is already everywhere in America.
Every line represents a real Comma device driving real miles on real roads. Not prototypes. Not test fleets. Real cars, real drivers, real adoption — with zero subscriptions.
While big tech argues about who will win the robotaxi future, thousands of people are already quietly using open-source self-driving today.
@comma_ai didn’t wait for permission. They built something people could actually own and use.
