Codex App Update: Conversation Forking & Slash Commands

Codex app now lets you fork conversations from any message, adds mid-draft slash commands for model switching, and fixes thread navigation bugs.

Codex App Update: Conversation Forking & Slash Commands

TL;DR

  • Fork conversations from any message, not just the latest turn
  • Slash commands now work mid-draft and control models/reasoning levels
  • Plan mode notifications so you don't miss when Codex needs input
  • Fixed thread handoff and subagent navigation bugs

New

  • Conversation forking from any message — Branch off from earlier turns instead of being locked to the latest message, giving you more control over exploration paths.
  • Slash commands mid-draft — Switch models and reasoning levels without restarting your prompt, and slash commands now work anywhere in a draft.
  • Plan mode notifications — Get alerts when Codex is waiting for your input so you don't miss blocking questions.

Fixed

  • Thread handoff and subagent navigation across worktrees and the VS Code extension — resolves routing issues when switching contexts.
  • Additional performance improvements and stability fixes.

Update via the Codex app or VS Code extension.
