This is truly the new model's answer ? It's pretty similar to 3.5's "reasoning" actually:

In this context, "3.10" and "3.11" should be interpreted as decimal numbers, not as numbers with more digits.

When comparing:

3.9 3.10 (which is equal to 3.1) 3.11 (which is equal to 3.11) We have:

3.9 is greater than 3.1 (3.10), because 9 is larger than 1. 3.11 is greater than 3.9, because 11 is larger than 9. Thus, 3.11 is the largest of the three numbers.
