I don't think he was saying their release cadence is a direct metric on their model performance. Just that the team iterates and improves the app user experience much more quickly than on other teams.

He seems to be stating that app release cadence correlates with internal upgrades that correlate with model performance. There is no reason for this to be true. He does not seem to be talking about user experience.

Oh c'mon, I know it's usually best to try to interpret things in the most charitable way possible, but clearly Musk was implying the actual meat of things, the model itself, is what's being constantly improved.

But even if your interpretation is correct, frequency of releases still is not a good metric. That could just mean that you have a lot to fix, and/or you keep breaking and fixing things along the way.

It's a fucking chat. How many times a day do you need to ship an update?
