What “checked” means

Auto-mode defaults, model behavior, and the corrected references were checked against official sources on September 28, 2026. Other command examples and links were checked September 24; older examples were not all rerun. Availability can change with your version, provider, plan, and organization. This guide does not update itself automatically.
