Codex CLI 0.98.0: GPT-5.3-Codex & Steer Mode Stable

TL;DR

  • GPT-5.3-Codex now available in Codex CLI
  • Steer mode is stable and enabled by default — Enter sends immediately, Tab queues follow-ups
  • Fixed TypeScript SDK resume bugs and model-switching instruction handling

New

  • GPT-5.3-Codex — New model available for Codex CLI users.
  • Steer mode stable by default — Enter now sends immediately during running tasks; Tab explicitly queues follow-up input for better control flow.

Fixed

  • TypeScript SDK resume with local images — Fixed argument ordering in resumeThread() so resuming with images no longer starts an unintended new session.
  • Model-switching instruction handling — Corrected developer instructions when changing models mid-conversation or resuming with a different model.
  • Remote compaction mismatch — Token pre-estimation and payload generation now use consistent base instructions, improving trim accuracy and preventing context overflows.
  • Cloud requirements reload — Requirements now take effect immediately after login instead of requiring a manual refresh.

Chores

  • Restored default assistant personality to Pragmatic across config and UI snapshots.
  • Unified collaboration mode naming and metadata across prompts, tools, protocol types, and TUI labels.
