FrontierThe story, in brief
Dynamic Languages Faster and Cheaper in 13-Language Claude Code Benchmark
Ruby, Python, JavaScript beat statically-typed languages by 1.4-2.6x on Claude Code. Cost: $0.36-$0.39 per run.
The KeyNews take
Why it matters
Claude's code generation efficiency varies dramatically by language choice—dynamic languages are significantly cheaper and faster, shifting the calculus for enterprise AI coding tools and developer productivity ROI.
The key facts
6 to know600-run benchmark across 13 languages

Publisher excerpt: A 600-run benchmark by Ruby committer Yusuke Endoh tested Claude Code across 13 languages, implementing a simplified Git. Ruby, Python, and JavaScript were the fastest and cheapest, at $0.36- $0.39 per run. Statistically typed languages cost 1.4-2.6x more. Adding type checkers to dynamic languages…
