Google is already sending notices that the 2.5 models will be deprecated soon while all the 3.x models are in preview. It really is wild and peak Google.

Like building on quicksand for dependencies. I guess though the argument is that the foundation gets stronger over time

What dependancy could possibly be tied to a non deterministic ai model? Just include the latest one at your price point.

Well it’s not even performance (define that however you will), but behavior is definitely different model to model. So while whatever new model is released might get billed as an improvement, changing models can actually meaningfully impact the behavior of any app built on top of it.
