When to use it

  1. Enable experimental voice conversations on a supported build before trying /voice.
  2. Inspect experimental toggles during onboarding so team docs match actual feature flags.

Effects and persistence

Lets you select experimental features offered by the installed build. Follow its activation and restart instructions.

/experimental opens controls for optional Codex features. Some changes may require a restart.

Voice conversations in 0.155.0

On supported builds, enable voice conversations through /experimental, then run /voice. This remains experimental and build-dependent.

Cautions

  • Treat experimental toggles as version-sensitive.
  • Do not put experimental behavior into team standards without a version and rollback note.
