I'm...weirdly unsurprised by this.

I've had a lot of luck getting LLMs to do interesting things with raw tabulated data.

Here's an example, plug this into the model of your choice:

  Here's a puzzle: what is this data from?

  39.0 2582 8.8 24
  39.2 2592 9.6 22
  39.4 2607 5.4 15
  39.6 2619 11.5 30
  39.8 2620 10.8 28
  40.0 2622 5.9 16
  40.2 2642 13.1 28
  40.4 2654 8.8 18
  40.6 2656 3.6 9
  40.8 2665 5.7 12

This is raw data I have laying around that's not from the internet and not part of any training set. It should be able to tell you A LOT about what's going on here, including multiple specific "make and model" type things.
