want to do a project to see under what conditions certain models outperform / underperform compared to others / baseline

I would need a lot of data on past predictions and I can't seem to find a good resource

Open meteo only goes back to like mid 2025 for the newer ai models. I know those are relatively new (like early 2024) but couldn't find any data from that far back, maybe its not public.

I was also wondering if there were any backtests for these models, like using data from the past to make predictions in the past using the updated models
