I don't have that toggle (but could indeed have sworn I saw it earlier).
Sorry, I have always thought that "opting in" is, "opting for the presented option" and opting out is "opting out of it", so opting out [of sharing prompts for training] is choosing to not share, but apparently I was wrong my whole life. I'm not a native speaker, and I think most people here (in my country) would interpret this the way I do? Weird but TIL.
If you opt in it means that by default you're not in and you chose that option. So if you're now included in training by default, then it's an opt-out feature as in you can opt out of it.

You don't see "Allow the use of your interactions with Vibe to train Mistral’s AI models" at https://admin.mistral.ai/vibe/privacy ?
And "Allow the use of your API calls to train Mistral’s AI models" at https://admin.mistral.ai/plateforme/privacy ?
I think there is a simple, unambiguous way to describe this, which is to use the passive voice or an explicit subject with the past tense to clarify that you didn't do the opting in.
Saying "we were disappointed to be opted in to training by default" clarifies the point you're trying to make, which is that the toggle (whatever it may be called) was set to training by someone else, not you.
Actually in your case you'd say "...after being disappointed that the Pro tier opted us in to training on prompts by default", which gives an explicit subject ("the [Mistral] Pro tier"). No one will confuse that with the opposite "the Pro tier opted us out of training on prompts by default".
You said it correctly, there’s no confusion.
FWIW I don’t find what you wrote confusing, but I do think it is following a sort of… bad convention that some companies have been pushing.
Opt-in and opt-out describe the nature of the choice that you make. “Opt” means to choose (apparently it is a French word we stole). Opt-in means you have to proactively choose to be in. Opt-out means you have to proactively choose to be out. “Opt-in by default” is an overly verbose way of saying “opt-out.”
In either case it describes the choice that you need to proactively make to override the default behavior.
Edit: I should also say that it is a “known point of contention” where pro-privacy people have been pushing back on this phrasing. So, you have probably accidentally stumbled into an ongoing discussion, which is why some of the comments might be unexpectedly prickly.
