New Benchmark Tests AI Coding Agents on Real-World Refactoring
A developer benchmarked OpenAI's Codex on a full-stack task manager, measuring both greenfield build (34 min) and refactoring (42 min) with authentication and migration. The test included 16 backend, 1 migration, and 25 frontend tests passing, plus lint, type, and browser checks. The author argues that simple code generation tests miss the harder problem of maintaining stateful systems.
Meridian48 take
The benchmark is a useful case study but lacks reproducibility and controlled comparison, so its results should be taken as illustrative rather than definitive.
