Ethical meaning : “private”, "anonymous, “not training with your data”, “no censured”, “open source”…

Yes. You have to be careful with the meaning of “ethical”. Most often, people write about “ethical AI” to demand money for copyright owners.

Case in point: Some people say that AI is only open source if the training data can also be shared freely. That means the training data has to be public domain or that permission by the copyright owner was obtained. If that’s what you mean by “open source”, then your options are extremely limited. EG some offerings from AllenAI.

Uncensored is also tricky. Many say that ethical AI does not output bad content. Of course, what bad content is depends very much on who you ask. The EU or China have strict legal requirements but not the same, of course. In any case, when you train an AI, you steer it to generate a certain kind of output. Respectable businesses don’t want NSFW stuff. Some horny individuals out there want exactly that. So it depends on what you want.

Check out the SillyTavernAI subreddit (and also LocalLlama). There you find people who value private, uncensored LLMs, though not necessarily copyright. It’s also where the above-mentioned horny individuals hang out for related reasons.
