Big knowledge cutoff jump from Sep 2024 to Aug 2025. How'd they pull that off for a small point release, which presumably hasn't done a fresh pre-training over the web?

Did they figure out how to do more incremental knowledge updates somehow? If yes that'd be a huge change to these releases going forward. I'd appreciate the freshness that comes with that (without having to rely on web search as a RAG tool, which isn't as deeply intelligent, as is game-able by SEO).

With Gemini 3, my only disappointment was 0 change in knowledge cutoff relative to 2.5's (Jan 2025).

What makes you think that?

It's simple. You take the existing model and continue pretraining with newly collected data.

A leak reported on by semi-analyses stated that they haven't pre-trained a new model since 4o due to compute constraints.
