the 3.5 pro pretrain was a complete disaster, they shelved it and are now working on gemini 4.

3.0 flash -> 3.8 flash is all post training which is pretty impressive.

Do labs come back from disasters like GDM’s 3.5 pretrain? I am thinking of Meta’s Llama 4. Meta is just now starting to be taken seriously again but they are definitely not at the frontier. And when I say “come back” I mean have an Opus 4.5 moment, which was really mind blowing for me at the time. Fable was a similar leap, just not as big.
