Title is mildly misleading, to say the least.

The blog attempts to solve 3 of 24 (thats 12.5 %) of advent of code 2022, and if you read along you'll see OP only had success on the first task of day 1, which would make a more correct title as "AI solves 2% of Avent of Code 2022" (assuming 2 tasks each day).

Do note that AoC tends to start with hello-world style tasks and increase in difficulty.
