Codex 0.164.0
Saved prompts, one-line settings
Codex 0.164.0 adds /presets, inline /model and MCP sign-in
Codex CLI 0.164.0 lets you save reusable prompts and slash commands in ten numbered /presets slots. The /model and /permissions commands now accept inline arguments to set the model, reasoning effort, speed or permission profile in one go. Enterprise MCP connections gained new sign-in options, including OAuth clients that need secrets.
