@HaydenRydalch Nah, we're still looking around on the inline VP market.

For now, we got a Rehm batch oven that's coming in this week actually.

[comma @comma_ai]

Looking at an Asscon VP2100 inline oven. Anyone have experience with Asscons? Should we consider anything else?

Use code LOLMAPS for $0 off a comma four for your Rivian

[Mike Kantorski @Mikekantorski]

Today my Rivian chose violence and decided the road I use highway assist on everyday is no longer available.

@RealGautamAtri @itskyleconner We really got our -$999 worth!

[comma @comma_ai]

@sheaduncan_ It should be very doable!

@PD0WM wrote a great blog post about similar work https://t.co/fKU2zfpXVT

How good would this F150 look with a comma four?

@naisomied We enforce terms for using our hardware (aka cloud services), mostly for compliance with safety standards.

But we absolutely don’t (and can’t) disable your hardware. You have root on your hardware, and we do not.

SunnyPilot is becoming the Ubuntu of the openpilot ecosystem. Who will be the Arch, Fedora, and Nix?

[Mike LaBarbera @ANSR42]

What is Sunnypilot?
Sunnypilot is a popular community fork of Openpilot that many Comma users (including me) prefer for daily driving.
You use the same Comma hardware, but run Sunnypilot software instead. You install it by choosing the “Custom Software” option when setting up your Comma device.
It keeps everything great about Openpilot while adding useful improvements and features like MADS (steering assistance even when your cruise control is off), and more driving models with tuning options.
And one of my favorites: Sunnypilot has its own excellent Sunnylink web app. From your phone or laptop, you can monitor your device, switch models, push updates, and change settings remotely — all without needing any cloud account.
Still 100% open-source, free, local, and you own everything. No subscriptions.

@Azobocse Come in the Discord and ask around

@nickneely00 We maintain and ship a minimal distro right now, but we'll see how it plays out!

We mostly want to build the intelligence kernel, but Google still ships AOSP on their own hardware.

@Out_of_Spec takes Uncle Tony's Adventure Pilot branch of @comma_ai's Openpilot out on the track on their Gen 1 Rivian. https://t.co/SWxhmyp0OS

Who wants to join our product team and finish Project F*ck Azure?

The final step is making our app (comma connect) p2p, for a better user experience and alignment.

We just moved all of our metrics from the cloud to our own datacenter. Data goes directly from users to our computers for training, debugging, and metrics.

We've always trained models without the cloud, but now only user-facing services are left in the cloud.

@adamhearn The problem is the cloud

@RobR3D We’re hiring someone to run the new prototype machine shop.

Two requirements for this job: CAM experience and motivation to build things.

Who’s ready to make chips?

[comma @comma_ai]

Interns welcome too of course!

The magic of iteration!

[Mike LaBarbera @ANSR42]

The @comma_ai 4’s cooling game is legitimately impressive.I honestly haven’t even noticed when the fan kicks on.They engineered a custom “MAX cooling system” around the Snapdragon 845 MAX chip, bigger central fan + optimized airflow channels that pull way more air than the 3X. Result? Continuous performance with zero thermal throttling, even when it’s baking on your windshield in 90°F+ Wisconsin summer heat. And it stays nearly silent. No more random fan screaming or forced cool-downs like older units. This is what real-world open-source hardware looks like, built for ownership, not planned obsolescence.
