Chestnut pairs a Radeon RX 9060 with comma four to run 1B-parameter driving models—30x larger than prior on-device models—via a passenger-footwell-mounted kit.
Summary
Developers building autonomous driving stacks can now prototype larger models on consumer hardware without desktop labs. The shift from 10W to Tesla HW4-equivalent compute unlocks MLSim-scaled training pipelines that ingest 15% of the comma fleet's million daily driving minutes.

Implementation verdict
Replaces comma four's cellular-compute constraints with discrete GPU acceleration. Requires 12V power, physical footwell/seat space, and openpilot 0.11.2+. Ready now: $799 kit ships today with 30-day trial and one-year warranty. Worth trying if you're iterating on end-to-end driving models at scale.
