"These chat transcripts may even be read by human reviewers."

PSA: This is true of all the frontier model providers even if you disable activity tracking.

They are all constantly monitoring your interactions for problematic behavior.

That is, fundamentally the marketing ploy of “AI Safety”.

For an AI system to be “completely safe”, like a self-driving car, it must map the full environment it operates in and be taught the “right way” to handle every conceivable scenario.

So when you present it with novel data or a situation, that constitutes an “AI safety event”, which per their ToS is a carve out for training on your session.

Further, go read the ToS carefully about what you opt out of. You’ll note there’s nary a mention of tool calls. You’re only opting out inputs (what you type) and outputs from the model from being trained on. All the content of the tool calls made while running on your system are fair game for training.

There is no way this is true, no? This'd mean literally all codebases people are working with have been trained on. There's no way anyone would use these guys if that was the case?

Why are you using it if you don’t want it to get better whose data is it supposed to get better on just somebody elses, not yours?

They're supposed to be focused on genuine training improvements over existing data, including via RL. Gathering data under the table is misaligned behavior.

I am providing RL via our chat logs.?!

> including via RL.

Can you please expand on what you believe RL looks like in this context?

Well for us Europeans, GDPR explicitly allows them to store pretty much anything if somebody can claim it’s for safety.

It’s literally just complicating things and providing zero reassurance to us AI customers.

For safety - hmm new for me (European), please elaborate.

You don’t need user consent to retain data that’s arguably needed to provide the service itself. I guess, safety falls into that category. Training on that data is probably a grey area, if they can guarantee it won’t contain PII. They have stolen all the internet, so I wouldn’t bet highly on their restraint.
Re:Tell HN: Gemini trains on chat history, even for subscrib... by Dylan16807 on Thursday November 05, 2026 @05:48AM (#50377631)
It's very easy to prove that training is not necessary to provide the service, because whenever you're using a model it's static and the training only maybe goes into new models.

It doesn't say for whose safety. It's certainly not yours.
Re:Tell HN: Gemini trains on chat history, even for subscrib... by petre on Sunday November 08, 2026 @09:03AM (#50413472)
For safety = for the Stasi equivalent.
Re:Tell HN: Gemini trains on chat history, even for subscrib... by zombot on Friday November 06, 2026 @12:30AM (#50388573)
Additionally, how stable are those ToS? Do they change every few days, like their models?
Re:Tell HN: Gemini trains on chat history, even for subscrib... by gkcnlr on Wednesday November 04, 2026 @10:57AM (#50367449)
The sole reason LLMs has gotten this good is because their aggressive expansion has been accompanied with literally this. The amount of uncredited information these models have been fed must be astonishing, also terrifying.

Why do you think they’re getting into consulting now?

Imagine all those tasty confidential IP and contract documents they have ingested. You couldn’t buy those.

Re:Tell HN: Gemini trains on chat history, even for subscrib... by synalx on Wednesday November 04, 2026 @03:03PM (#50370753)
I think the heavily subsidized subscriptions are exactly for this purpose - the training data they generate is worth the high subsidy.
Re:Tell HN: Gemini trains on chat history, even for subscrib... by red-iron-pine on Wednesday November 04, 2026 @04:07PM (#50371533)
i mean openai basically said as much, no? it's free for all so that they can train the models better and get real world interaction data.

Yes, Altman called it the data flywheel in 2022.
Re:Tell HN: Gemini trains on chat history, even for subscrib... by terramauthe on Wednesday November 04, 2026 @11:50PM (#50375334)
yeah, but in 2026 the interaction data of the average user isn't adding much to training. only the really exceptional users.
Re:Tell HN: Gemini trains on chat history, even for subscrib... by cma on Friday November 06, 2026 @05:00AM (#50390387)
They can filter for the exceptional users, but the data flywheel is also about getting access to private codebases, not just the interaction in the chat.
Re:Tell HN: Gemini trains on chat history, even for subscrib... by jpardoe on Thursday November 05, 2026 @08:41AM (#50378944)
They're almost certainly making a profit on subscriptions.
Re:Tell HN: Gemini trains on chat history, even for subscrib... by cj9 on Friday November 06, 2026 @06:53AM (#50391262)
Right, but they are also certainly looking to make higher profits overall by avoiding having to pay for large amounts of (confidential and/or private) training data.
Re:Tell HN: Gemini trains on chat history, even for subscrib... by jpardoe on Friday November 06, 2026 @09:22AM (#50392610)
Seems smart.
Re:Tell HN: Gemini trains on chat history, even for subscrib... by fierycatnet on Wednesday November 04, 2026 @03:16PM (#50370891)
I can guarantee you that multiple people are reviewing some chats. This is very similar to Apen and whatever company prior to that for reviewing Google searches. They'd hire out contractors with NDA.
