Earlier quoted context omitted.
All 3 models you ranked cannot get "how many r's are in strawberry?" correct. They all claim 2 r's unless you press them. With all the training data I'm surprised none of them fixed this yet.
When using a prompt that involves thinking first, all three get it correct. "Count how many rs are in the word strawberry. First, list each letter and indicate whether it's an r and tally as you go, and then give a count at the end." Llama 405b: correct Mistral Large 2: correct Claude 3.5 Sonnet: correct
For example, the latter model answered with:
To count the number of Rs in the word "strawberry", I'll break it down step by step:
Start with the individual letters: S-T-R-A-W-B-E-R-R-Y Identify the letters that are "R": R (first one), R (second one), and R (third one) Count the total number of Rs: 1 + 1 + 1 = 3
There are 3 Rs in the word "strawberry".
