Mistral now trains on user input by default, except on enterprise tier

Mistral's default data handling has changed: user input and output may be used for model training unless you opt out. Vibe and API users are not opted out by default, but enterprise customers are. Opt-out toggles are separate for Vibe and API, and can be managed via the Admin panel or mobile app settings. This help article details the exact steps to disable training data sharing.

Vibe: users are not opted out by default and can opt out at any time in their settings.

    Context: After careful research our organization preferred a European partner with good central privacy controls. We landed on Mistral, after being disappointed that the Pro tier was opt-in to training on prompts by default we switched up to the Team tier which provides an organization dashboard with some relevant settings. As we did that Mistral changed these options and the Team tier was now also opt-in by default and at the same time seemed to have lost the ability to centrally disable training on prompts for your entire organization. This even caused some of our (testing) prompts to be used for training (which Mistral removed after we expressed our disappointment).

    For some time these pages conflicted with what our users reported (they said that in contrast to what I stated to our management they found they were opted into training on prompts by default as per their own privacy page). Mistral just now corrected their docs. I'm not sure how long the conflicting situation has lasted, but at least for several days.

    For contrast: Claude disables training on prompts for organizations starting from the 18 euro tier [0]. As a European I'm disappointed.

    I pay for a subscription to Duck.ai mainly because I don't want to be constantly fighting my vendor to protect my privacy.

    Microsoft already did a rug pull on me and opted me in to training months after I signed up with Github Copilot. It exhausting and ultimately futile to monitor these companies.

    It's not guaranteed that Duck.ai will continue to uphold its promise of not training on your sessions — if the company gets bought by Microsoft, it's only a matter of time before the switch to "you can opt out at any time". But since privacy is Duck.ai's brand, it will be somewhat harder for them to hide what they're doing should they betray their customers.

    I also don't actually trust that Duck.ai sub-vendors OpenAI and Anthropic will uphold whatever contract they have with Duck.ai — the whole AI business model is built on lawless consumption of others work.

    We'll ultimately have to run our own models locally, because it's impractical to defend against untrustworthy AI vendors.

    This is a hugely misleading editorialised title.

    The page title is "Can I opt out of my input or output data being used for training".

    Right at the top of the page it says "In certain cases, your input and output data (such as conversations, documents, and other user-provided content) may be included in Mistral’s model training programs. You retain full control over this processing and have the right to opt out of these programs at any time."

    I could be mistaken, but wasn't Mistral openly championing themselves as a company and EU option that wouldn't do this/didn't do this?

    > Vibe: users are not opted out by default

    > Vibe (Enterprise): customers are opted out of training by default

    So they made it opt in for enterprise (how it should be), but intentionally made opt out for regular user.Basically saying "screw you: to regular users.

    Any self respecting user should stop using them.

    I remember this being the default for a while already. When I signed up and got an API key, I remember I did turn off the training option specifically, so it must have already been a default to have training on input on.

    There are so models that beats all of Mistral models, plus you can run many of them locally. Why would anyone run Mistral?
