What do you mean "at least here"? What's wrong with other usage? They are using OpenAI so they haven't trained it themselves and is just inputting the Wikipedia article as a prompt. I don't see how that is more respectable than literally every other service built on OpenAI.

Right in the release:

DuckAssist answers questions by scanning a specific set of sources — for now that’s usually Wikipedia, and occasionally related sites like Britannica — using DuckDuckGo’s active indexing. Because we’re using natural language technology from OpenAI and Anthropic to summarize what we find in Wikipedia, these answers should be more directly responsive to your actual question than traditional search results or other Instant Answers.

You misunderstand how this works. They do not train it on Wikipedia. The Wikipedia article is part of the prompt. You can do this yourself by copy-pasting a Wikipedia article into ChatGPT and ask a question about it. The underlying LLM is still GPT-3 and trained on everything on internet.

I think the point is that it should only be used to summarize wikipedia information, and thus harder to use for other ethically murky purposes? But that remains to be seen; I haven't tried it yet.
