Can you expound on Opus 4.5 a little? Is it so good that it's basically a superpower now? How does it differ from your previous LLM usage?

To repeat my other comment:

> Opus 4.5 is categorically a much better model from benchmarks and personal experience than Opus 4.1 & Sonnet models. The reason you're seeing a lot of people wax about O4.5 is that it was a real step change in reliable performance. It crossed for me a critical threshold in being able to solve problems by approaching things in systematic ways.
