Curious logic. Does Google want you to use it or not? Do they want to be paid for tokens or not? why segregate open and closed?

It's not parameter size - there is apparently such a thing as "Gemini Nano", which famously is downloaded automatically by Chrome. How similar is it to Gemma E4B? And how strange - you have the weights, but you don't "have" them?

You can actually get the gemma-4 models on a per-token API basis, you just have to click some extra buttons (in GCP). Not the same for other open weight models. For those they make you run your own hardware.
