I was more interested in how it reasoned to form haikus rather than which people chosen. And interested in Adrian's rich details for them. I just reran the search with explanations turned on, and yes it was based on a literal acceptance of 10 web pages. I think I could tell it to be skeptical and not rely on compilation lists, but might then need to get behind book paywalls. Supposedly it sneaked past entire NYT archive paywall, and that influence may be why it once made a woke attack against an innocent question of mine.
I used to be skeptical against this mindless pattern-matching neural network approach, but found they can discover the rules of logic without being taught. That's why I use the R1 version of deepseek, which stands for reasoning. As for learning facts, deepseek is famous in only spending a few million in training vs a hundred+ million for competitors, yet getting similar results. Assimilating facts is costly but straightforward. Complex reasoning is badly done by humans, and seems ripe for automation. If you can prove reasoning capability thru explanations, then you might justify more investment for loading in facts.
P.S. A crippled (lite) version of Chinese deepseek can be downloaded to run on laptops, but there is a U.S. law proposing 20 years of prison for that (for espionage). I showed how to run the powerful web version in a topic something like 5 worst Roman emperors.
