AI vs. logic puzzles, part two

A little over a year ago, I experimented with seeing is the current AI models could do logic puzzles. I used to do these kind of puzzles often when I was a kid, in the pre-interweb era. At the time I tested them, they all failed to solve the puzzles correctly. Fast forward to today, and the release of Anthropic’s Claude Fable model.I gave Fable the same logic puzzle that the earlier Claude model failed. Here is my initial prompt. Took less than a minute for Fable to respond. The answer was correct and even presented in a nice table. It even brags a little about it’s speed. This kind of reasoning is difficult and this is a marked improvement from the last test. LLMs still have a lot of issues with guessing, going down rabbit holes, and not sticking to Occam’s Razor, but improvements in this kind of reasoning is impressive.
