Ben Nadel runs a small code refactoring task — moving a ColdFusion custom tag from a global shared folder to a subsystem-local folder — using three Claude Code models (Haiku 4.5, Sonnet 4.6, and Opus 4.6) to compare their performance. All three models produced identical code changes. Haiku was the fastest at 49 seconds, Sonnet took 1m 18s, and Opus took 1m 0s. The takeaway is that for small, clearly-scoped refactoring tasks, the lighter Haiku model may be sufficient and faster, though the test scope was very limited.
