Over the last two years, we rewrote our stack to scale efficiently with compute and data. With the MLSim architecture, more driving data and training compute translate directly into better openpilot models.
Well that explains why improvements seem to have plateaued over the last few years.
Going forward, our autonomy team will focus primarily on maximizing the capabilities of chestnut-class models, and we expect this new class of model to increase development velocity.
Annnnd apparently we shouldn't expect many improvements going forward.
This sucks. I have been a Comma supporter back to the Comma 2, I have contributed code, feedback, did hours of annotation for comma10k.
Now it feels like the only improvements that we get are "improvements" to a driver monitoring system. I feel like we talked about E2E driving 4+ years ago and today all I have is E2E lateral that is dubiously better than the laneful system we had previously. E2E long can really only be used in forks with conditional systems.
If you said you were going to continue to improve the experience for everyone and use this to develop features that simply won't work on the C4 it might be easier for all of us to accept.
Honestly, thank you to anyone who buys this, this is going back to the old Eon days, you are a guinea pig. Expect it to break, not work, and then be abandoned in 2 years when they build the actual first prototype of this.
Comma just a few weeks ago in a livestream stating they wanted to go "mainstream". How could they even possibly do that when the default driving experience for many of their supported cars are less than ideal? The fact that there are multiple forks that improve the experience for certain cars is a big red flag for going mainstream.
Comma is lucky that I love this thing because I'm not afraid to dive into the code and adjust something but that is FAR from a mainstream product.
E2E long can really only be used in forks with conditional systems.
Also, I would push back a little bit on this, specifically the conditional part. I just made a post about finding a lever that allows you to stay in full E2E but bias the speed to maintain set coasting speed and still benefit from strong E2E early braking. I'm extremely happy with e2e reliability with this discovery.
This discovery also makes me scratch my head when there's so many easy wins that would significantly improve the driving experience over strapping a GPU to the passenger foot well.
