The last page only links to generic Google policies. If they didn't train on it, they could've easily said so, which they've done in other cases - e.g. for Google Studio and CLI they clearly say "If you use a billed API key we don't train, else we train". Yet for the Pro and Ultra subscriptions they don't say anything.
This also tracks with the fact that they enormously cripple the Gemini app if you turn off "apps activity" even for paying users.
If any Googlers read this, and you don't train on paying Pro/Ultra, you need to state this clearly somewhere as you've done with other products. Until then the assumption should be that you do train on it.
Service Terms
17. Training Restriction. Google will not use Customer Data to train or fine-tune any AI/ML models without Customer's prior permission or instruction.

I originally thought they only supported the previous generation models i.e. Claude Opus 4.1 and Gemini 2.5 Pro based on the copy on their pricing page [1] but clicking through [2] shows that they support far more models.
Lately Copilot have been getting access to new frontier models the same day they release elsewhere. That wasn't the case months ago (GPT 5.1). But annoyingly you have to explicitly enable each new model.
Anthropic has an option to opt out of training and delete the chats from their cloud in 30 days.
And this is for hobby / portfolio projects.
