Codex CLI 0.145.0-alpha.18

0.145.0-alpha.16→0.145.0-alpha.18·July 16, 2026 at 6:16 PM UTC

Small alpha release: skill-selection internals are expanded, and the o1 model is recognized.

Changelog

  • [new] Adds the o1 model identifier.
  • [changed] Tightens client/protocol event handling around streaming chunks, collaboration wait lifecycle, and exec-command begin notifications.
  • [removed] Drops obsolete client ack and line-edit event paths no longer used by the agent loop.

Under the hood

  • Extends the dynamic skill selector with character n-gram and multi-query lexical matching modules so skill ranking can use richer query signals.
  • Adjusts typed config/capability surfaces (including environment status and prompts capability) and related thread-store / tool-summary shapes.
  • Refreshes dependency and version lock metadata for the alpha.18 build.
