A couple tidbits:

> Beyond today’s releases, Gemini 3.5 Pro is currently testing with partners and we plan to make it broadly available as soon as it’s ready.

> We have started our most ambitious pre-training run yet, for Gemini 4, and are excited by the progress.

While them fixing token bloat on 3.5 Flash is good work. That paragraph was the real highlight.

Hopefully 3.5 Pro is soon, and that Gemini 4 can be here end of year and finally have an updated knowledge cutoff.

What is a “knowledge cutoff” ?

—Ah, got it, it knows more about recent times.

I’d just like to add, and this may interest you both, that I’m not disagreeing with either of you. When 3.5 Flash first showed up in AI Studio, its model card said it had a March 2026 knowledge cutoff. After the backlash over it apparently knowing nothing past December 2024, the card was changed to read: “Knowledge cutoff: Unknown.” Maybe the timing was coincidental, but I doubt it.

I guess they meant to release Gemini 3.5 Pro shortly after 3.5 Flash, but then Mythos/Fable and later GPT-5.6 came out with higher performance than 3.5 Pro, so the managers decided not to release it.

That reasoning didn't stop them from releasing this batch of models, admittedly that may be less face to lose away from the flagship position.
