Huh? Maybe a third scenario is that AI helped fix the bugs? Like described in the actual post you are replying to? This level of conspiracy theory is getting a bit ridiculous.

I think you’re right, my base assumption is that the models can code and can fix bugs, and can code more in parallel and faster than humans at a lower cost.

If Google are tackling lower value bugs with AI the number is in a way inflated compared to some utility measure (fixing a smaller number of worse bugs could be preferable) but it’s still things fixed.
