I have no idea at all whether the GCP "Service Specific Terms" [1] apply to Gemini CLI, but they do apply to Gemini used via Github Copilot [2] (the $10/mo plan is good value for money and definitely doesn't use your data for training), and states:
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.

Thanks for those links. GitHub Copilot looks like a good deal at $10/mo for a range of models.
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.
Yes, it's a great deal especially because you get access to such a wide range of models, including some free ones, and they only rate limit for a couple minutes at a time, not 5 hours. And if you go over the monthly limit you can just buy more at $0.04 a request instead of needing to switch to a higher plan. The big downside is the 128k context windows.
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.
Yeah Github of course has proper enterprise agreements with all the models they offer and they include a no-training clause. The $10/mo plan is probably the best value for money out there currently along with Codex $20/mo (if you can live with GPT's speed).
That's the main reason, why I hope Google does not win this AI war.
That's good to know, thanks. In my case nearly 100% of my code ends up public on GitHub, so I assume everyone's code models are training on it anyway. But would be worth considering if I had proprietary codebases.
Are you sure about OpenAI? I thought they actually do retain your agent chats (training I am less concerned about personally).
Anthropic has an option to opt out of training and delete the chats from their cloud in 30 days.
I was only talking about training so you're probably right about retention - I care more about training.

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.
