It's "experimental", which means that it is not fully released. In particular, the "experimental" tag means that it is subject to a different privacy policy and that they reserve the right to train on your prompts.
2.0 Pro is also still "experimental" so I agree with GP that it's pretty odd that they are "releasing" the next version despite never having gotten to fully releasing the previous version.
Thanks. I think my post lacked clarity of what I was talking about. I meant that most people care about API access to use with their favorite editor. It's a big limiter with grok, for example.
But I did mingle that with my knowledge of google's history of releasing without releasing these models which, as you point out, isn't true with this release.
