Warn HN: DuckDuckGo is doing AI summaries for search results now?

Searching for "steam deck gamescope"[0], the first search result looked suspiciously autosummarized[1]. Refreshing the page seems to generate new summaries every time, for the exact same query[2][3].

None of these quotes appear in the page itself[4], in the content or source code.

There is no warning that this is happening, nor can I see a way to turn it off. Curiously, it only seems to happen for the first result, the other results' summaries appear verbatim in their respective pages.
