- Understands user intention better than before; I’d say it’s better than Claude 3.7 Sonnet base and thinking. 3.5 is still better at this (perhaps the best) - Again, in raw quality code generation, it is better than 3.7, on par with 3.5, and sometimes better. - Great at reasoning, much better than any non-reasoning models available now. - Better at the instruction following than 3,7 Sonnet but below 3.5 Sonnet.
