about this event
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.
We bring: chestnuts and comma hardware; Desktop GPUs; Food, drinks, and workspace; The comma team.
You bring: Your laptop; Your favorite agent; A good idea.
Schedule: Friday, 6 PM — Doors open; Friday, 7 PM — Chestnut kickoff; Friday–Sunday — Hacking; Sunday, 3 PM — Demos and judging; Sunday, 6 PM — Winners announced and wrap-up.
Prizes: 1st place: comma four + chestnut + $2,500; 2nd place: comma four + chestnut + $1,500; 3rd place: comma four + chestnut + $750.
Apply here by September 8. We're handpicking the strongest applicants on a rolling basis until then. Great GitHub profiles, leaderboard submissions, and openpilot contributions are a plus.
Want us to fly you out? We'll cover flights for the first two people who get a top-three score on any active leaderboard challenge.
