COMMA_HACK 7

COMMA_HACK 7

September 18–20, 2026
Friday 6 PM – Sunday 6 PM
In person at comma HQ in San Diego, CA

COMMA_HACK is back for a weekend with big models and big GPUs.

Come see what openpilot can do with more compute, hack alongside the comma team, and build something worth demoing on Sunday.

Chestnut is the easiest way to throw real GPU compute onto your embedded projects. It connects to any device with a USB port, all the way down to USB2—including your laptop, Raspberry Pi, comma four, and Android phone.

Build with chestnut, work on openpilot, or make something entirely new.
