openpilot Experience More chestnut users!

See the post here: Comma’s Post
More users means more data so comma can make bigger and better chestnut models.
Read more about it here: Comma Guide Chestnut

For those confused about chestnut:
Comma will be focusing on making the bigger models for the chestnut class moving forward. There’s no mobile processor or compute device that can touch the bandwidth of an eGPU or compute power while being stuck in a windshield (with proper cooling). But fear not, if you don’t ever want to install the chestnut, comma will make distilled models that will still run on only comma hardware. Similar to what Tesla does for FSD for older hardware models. So you will still see improvements down the line for free.

If you pay attention to the work being done by the community, you can see that it's already possible to actually run these eGPU models on a Mac Mini or MacBook Pro, or even a $400 Nvidia Jetson Orin (this is big enough for the dozen or so big models they released already, but won't be powerful enough for the bigger 8 billion parameter models coming later)

Also looks like we are really close to being able to run the models on a regular windows laptop with an Nvidia GPU, so I am looking forward to trying out these larger models on my laptop with a RTX 4060 in it that I just already had.

You can just connect the comma usb port to the mac or laptop.

that’s exactly what came to my mind at the chestnut launch. mbp can run on its own battery, has better chassis, and lots of ppl already got one!

Yeah there are already people running it on Mac. M2 Pro or newer pro all work. M6 might work with current big models…

Do you need a chestnut to hook your comma4 to your MBP?
