A deep dive into Kimi K2 and Grok 4 for real-world coding, comparing their performance across bug fixing, feature implementation, tool use, and cost efficiency. See which model stands out and when to choose each for your dev workflow.

I tested Kimi K2 and Qwen-3 Coder on 13 Rust development tasks across a 38k-line codebase and 2 Frontend refactor tasks. The results reveal differences in code quality, instruction following, and development capabilities.

I pitted Claude 4 Opus against Grok 4 in a series of challenging coding tasks. The results highlight trade-offs in speed, cost, accuracy, and frustration factors that every dev should know.
