TESTING OPENAI CODEX AND COMPARING IT TO CLAUDE CODE

Summary from the TLDR Web Dev newsletter

OpenAI Codex and Claude Code can both be used as command-line AI coding assistants. This developer tested them on a JSON file merging task. Codex successfully completed the task with detailed explanations, while Claude Code wasn't able to. Though Codex was less transparent about its process, it was powerful and successful, which means it may be more useful for experienced devs over vibe coders.
