Judging from the icons, this is DuckDuckGo’s “Search Assist” and its first results are hit or miss because they’re optimized for speed, apparently at expense of accuracy. If you expand the “More” and continue the conversation it switches to DuckAI and realizes its mistake.

I was able to navigate my migration process using ChatGPT but you should always verify. If you don’t understand how these tools work, you can always ask them to provide sources.
