So....just from my personal experience.

When we started getting access to Claude last year, it was barely competent at C++. Like someone who read a book about C++ but never actually wrote any, or had to debug any issue. It would confidently declare things which any C++ programmer could tell you were bollocks straight away.

But....now it's able to reason about things like memory management, thread safety and second order effects when multithreading very very very well. It's honestly incredible how well it can understand C++ code and figure things out. Opus is already pretty good(although far from perfect) but Fable was just something else. I could give it a description like "It was reported that only sometimes(1/20 repro) when the user opens the inventory and closes it, they can't move the camera afterwards" and it was able to find out both the inventory camera control and input code and pinpoint the exact race condition that could lead to this situation.
