    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.

    Saving you a click:

    > 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%.

    > It cost about $1 for the tokens on OpenRouter.

      Question is whether other models would offer same optimization or was it exclusive to K3? Would have been much more interesting write-up.

      Yeah that was a short article

      $1 seem a lot, with a high cache hit rate it should be lower.

    TLDR: Kimi K3 is good, but the data point is minuscule.
