Pulumi has introduced new AI capabilities in its CLI, powered by Pulumi Copilot, to enhance infrastructure management by translating complex changes into clear explanations and providing actionable guidance for resolving deployment errors. These features, available in preview mode with the --copilot flag, aim to tackle the challenges of understanding preview changes and interpreting error messages by offering plain-language summaries and diagnostics. The "explain" option in the CLI provides a concise summary of pending infrastructure updates, helping users verify changes and identify potential issues. Additionally, the diagnostics feature simplifies error logs into actionable solutions, reducing resolution time. These features require Pulumi CLI version v3.171.0 or greater and the Pulumi Cloud backend, and feedback from users during the preview period will shape future enhancements before general availability.
