Codex is getting 94% faster

⚡️ Codex is getting 94% faster

This applies to long sessions. Previously, opening a huge chat meant Codex loaded almost the entire history at once. Now it will load only the part you actually need, and fetch the rest when needed. In OpenAI’s internal test, load time dropped from 27.6s to 1.66s.

Screenshot of benchmark results: 94% faster (27.62s → 1.66s), 87.8% less conversation-renderer JavaScript heap growth, 41.2% less whole-app memory growth, 98.2% fewer requests, 99.6% fewer transcript items loaded for a 741-turn / 231MB conversation.
