> Gemini on-prem boxes (recent release announced last week)

Do you have any more information on this? I only found this article about it: https://venturebeat.com/technology/googles-gemini-can-now-ru...

It mentions that Gemini can run on eight NVIDIA GPUs, but not which GPU and which Gemini model. Either way, this puts an upper bound of 288 * 8 = 2304 GB on the size of the Gemini model, which as far as I know has been a secret until now.

I have most likely outdated info, I left Google Research 4y ago. Back then, available TPU instances were plenty and GPU scarce. Nobody wanted to mess with an immature crashing compiler and very steep performance cliffs (performance was excellent only if you stayed within the guardrails, and being outside was supported and not even resulting in a warning - as it was so common in code). But I believe most of it has changed for the better for TPUs.
