Codex CLI 0.158.0-alpha.11

0.158.0-alpha.10→0.158.0-alpha.11·September 25, 2026 at 12:18 AM UTC

Patch alpha 0.158.0-alpha.11: the CLI now accepts the o1 model, the exclude_slash_tmp config key is gone, and internal work continued on multi-agent, MCP, and collaboration.

Changelog

  • [new] The CLI now recognizes o1 as a model identifier.
  • [removed] The exclude_slash_tmp configuration key is no longer supported.

Under the hood

  • Multi-agent v2 and code-mode configuration picked up additional settings, and MCP server config expanded (including enterprise-managed auth).
  • Further groundwork for collaboration modes, remote-control pairing, thread queues, and plugin install/pagination.
  • Session and thread identity handling, along with daemon telemetry handoff flags, were adjusted.
  • Older payloads around request-user-input, skill migration, and agent registration were dropped.

Upgrade notes

  • Drop exclude_slash_tmp from your Codex config if you still have it; it has no effect in this build.
