Tested Kimi K3 for Coding

The newly released Kimi K3 AI model successfully optimized a Rust function using SWAR (SIMD Within a Register) technique in about 15 minutes with no errors, achieving a 2% speed improvement at a cost of roughly $1. The author's experience suggests Kimi K3 lives up to its claims of frontier-level quality comparable to models like GPT, demonstrating both appropriate decision-making and flawless implementation on a real coding task.
