Codex supports switching reasoning levels mid-conversation without losing cache
Codex developers get an experience update: reasoning levels can be switched mid-conversation without invalidating the cache; use low reasoning for simple tasks and raise it when needed, with no need to rebuild context. The CLI is updated in sync, including reusable prompt presets, inline switching of models and permissions, long-session resume fixes, enterprise MCP login and Windows proxy authentication, and noticeably faster dot invocation connection speeds.
