Not off the top of my head... just on occasion I'd ask them to summarize out of curiosity. The most recent was what given people from history might select on the red vs blue button meme circulating this past week.

The differences between Claude, OpenAI and Grok can be very interesting to say the least. I feel that Grok tends to do better with recent/current events, and I find Claude a bit more balanced on historical events. Just my own take.
