A 600-run Claude Code benchmark building a mini Git across 13 languages found Ruby, Python, and JavaScript were the fastest.

@WaffleFries yep, this mostly measures first-pass generation cost, not what happens once the codebase starts changing. A typed language can be slower and pricier up front, but it will catch stuff like missing `parent` / null cases earlier when the code starts getting touched a lot.

@Yoshiii yeah, that’s the part these benchmarks miss. Dynamic code can be cheaper on the first pass, but once a codebase gets refactored a lot, static checks catch stuff like null parent cases before they turn into review churn or bug cleanup.
