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.
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.
Yes, because people will say that something should be opt-in, meaning off by default, and then someone makes it on by default and says 'oh, it's opt-in, you're just opted in by default!'
Opt-out = "we assume you are in unless you tell us you want to be out"
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 ?
at https://admin.mistral.ai/vibe/privacy:
Allow public sharing of chats content
Allow user feedback on model responses
Chat Retention Policy
At https://admin.mistral.ai/plateforme/privacy I see
Allow the use of your API calls to train Mistral’s AI models.
Enable Labs models
So indeed, no "Allow the use of your interactions with Vibe to train Mistral’s AI models". I only see that setting here: https://chat.mistral.ai/chat?profile_dialog=privacy And I have to ask every user in my org to go and turn it off.
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".
“disappointed that the Pro tier was opted-in to training on prompts by default” [and required manually opting out]
“the Team tier was now also opted-in by default” [and required manually opting out]
In context of each sentence and the larger comment, read smoothly here.
Also - have seen more than one lively discussion on these phrases, since defaults can stick 95% of the time and Big Tech has done their best to be abusive about what they automatically enable for users by default for some time.
