Yeah that was a short article

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

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

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.

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

TL? it's like 200 words long

Author couldn't be bothered to compare any other models? ok man
