Codex vs Claude Code: What the Numbers Actually Count

OpenAI Codex and Claude Code get compared in side-by-side charts every week, but those charts mix units. A 40 million weekly-active figure bundles Codex with ChatGPT for Work; a Stack Overflow survey puts Claude Code at 65.5% of agent users while a market-share report puts it at 29.4%. This episode digs into the measurement problem underneath the rivalry: bundled distribution versus paid installs, terminal-native execution versus cloud containers, million-token windows versus native compaction, and proprietary conventions versus an open standard. The honest answer to "who's winning" may be "pick a ruler" — but the reasons the rulers disagree are the interesting part.
