By mid-March 2026, Anthropic’s Claude Code was driving an impressive 326,000 public GitHub commits daily, more than double its February average of 135,000. This surge reflects why developers favor it over OpenAI’s Codex despite the latter’s ongoing use.
Compared side by side, Claude Code scored 72.7% on verified coding benchmarks, edging out Codex’s 69.1%. Its strength lies in handling complex, long-session coding tasks where keeping track of multiple past steps is key. Developers also praise Claude Code’s user interface and plugin ecosystem, which enhance productivity for intricate project demands.
While Codex offers better cost efficiency for simpler, well-defined tasks, enterprises are increasingly moving toward Claude Code for projects requiring consistent quality and regulatory compliance, especially in sectors like finance and healthcare. Many firms now blend both AI agents: Claude Code tackles context-heavy challenges, while Codex manages routine assignments to balance cost and performance.
