A bit tangential, but I've found 4 Sonnet to be much, much better at SIMD intrinsics (in my case, in Rust) than Sonnet 3.5 and 3.7, which were kind of atrocious. For example, 3.7 would write a scalar for loop and tell you "I've vectorized...", when I explicitly asked to do the operations with x86 intrinsics and gave it the capabilities of the hardware. Also, telling it to use AVX2 as supported would not make it use SSE or it would make conditionals to use them, which makes no sense. Seems Claude 4 solves most of that.

Edit: that -> than

This fits my experience. I’m definitely getting considerably better results with 4 than previous Claudes. I’d essentially dropped sonnet from my rotation before 4 became available, but now it’s a go-to for this sort of thing.
