AI question and rate plans for using on phone

I just got my reminder that my free year of Google AI Pro is expiring next month. It looks like it's $27 usd/mo. That's high for me and my question is, if I don't subscribe to that, will no AI features work on my phone? AI assistant or integration w/ calendar or anything?

I'm looking at this:
