UnverifiedIn the experiment, Codex delivered an answer that ran through in one pass with zero errors, and its solution was to optimize the handover package to help creators enter the scripting stage faster.72% similarUnverifiedCodex responds slowly but thinks deeply, tending to thoroughly understand the codebase before taking action, making it suitable for deep refactoring.65% similarUnverifiedCodex is cheaper than Claude and more reliable and stable when handling complex back-end logic, but performs worse on front-end design.62% similarUnverifiedAfter connecting to a third-party model, Codex's execution of complex tool calls and computer-control features is degraded—writing code and modifying files is largely unaffected, but the failure rate of multi-step automated operations increases significantly.62% similarUnverifiedCodex's cloud environment has issues with incomplete package management, and lint tests frequently fail due to missing dependencies (such as the next command).60% similar
