Should have given the other frontier models a chance too? What if Fable or GPT-5.6 would have found a 30% speed up? Not like a sample size of one means much though.
Yeah, I'm not sure what the purpose of this article is. I don't have a lot of experience with Rust, but I think this is the type of task even Opus 4.5 could do.
> I decided to try it out and see if it could optimize my Rust program.
> Kimi K3 had 2 recommendations, and I decided to have it pursue the SWAR optimization—SIMD Within a Register. With SWAR, a single 64-bit value is treated as 8 eight-bit values—so we can handle 8 u8 values (single-byte) at once.
> Kimi K3 took about 15 minutes for the task, and it completed it perfectly. I found the optimization sped up the program by 2%.
