Is Gemini 4 Argon free?

No. On the free plan it is locked. Google AI Pro unlocks it: €5.49 for three months, then €22 a month (Germany, checked 20–21 October 2026).

Does Google train on my Gemini chats?

With Keep Activity on, which is the default for adults, Google uses your chats to train its AI models, and some are read by human reviewers and kept for three years. With it off, chats are not used for training and are kept for 72 hours.

Gemini 4 Argon is now in the Gemini app, but only on a paid plan: Google AI Pro is €5.49 for three months, then €21.99 a month (Germany). On the Vals Index it ranks third, behind Claude Sonnet 5.5 and Opus 5.5, but ahead of OpenAI's GPT-6 Astra. The real catch is your data: with Keep Activity on (the default if you're 18 or over), your chats can be used to train Google's models and some are read by human reviewers. Turn it off in Settings.

Gemini 4 Argon is finally in the Gemini app. I paid for it, so you do not have to. On the free plan, it's locked. You cannot use it. Pro unlocks it. €5.49 for three months and then €22. Is it the best model today? Not quite. It's third on the Vals Index, but it beats OpenAI's best, GPT-6 Astra. So Google or OpenAI, honestly, Claude is still winning. Sonnet and Opus 5.5 are number one and two. But if you use Argon, the real catch is your data. With Keep Activity on, Google uses your chats to train its AI models.

Some are read by human reviewers and kept for three years. This is a default option. My advice, turn it off. Data will not be used for training, and chats are kept for only 72 hours. So use it for your personal work, not for your client's contracts. Settings. Keep Activity. Off. then use it.
