Pulumi Neo: an AI "platform engineer" agent for infrastructure

2025-09-16 · Publisher : Pulumi · Domain : Cloud & DevOps

On 16 September 2025, Pulumi launches in public preview Neo, an agent that automates infrastructure changes across repositories, using Pulumi policies as guardrails and requiring human approval.

What changes

  • Pulumi Neo launches in public preview on 16 September 2025.
  • The agent changes infrastructure across several repositories, through pull requests.
  • Pulumi policies, RBAC and audit trails serve as guardrails.
  • Human approval is required for changes.

### Background On 16 September 2025, Pulumi introduces Neo, an AI agent designed for platform engineering teams. Neo automates infrastructure tasks by understanding cloud context, infrastructure-as-code, secrets management and compliance requirements. It is in public preview as of the announcement date. ### Key facts - Neo works across several repositories at once and creates pull requests validated by existing policies. - Pulumi platform features (policies, RBAC, audit trails) serve as the agent's operational guardrails. - Changes require human approval; the agent respects the organization's security standards. - Pulumi frames it as an answer to the "velocity trap": AI tools speed up developers, but not the teams that govern infrastructure. ### Why it matters The challenge is for infrastructure to keep pace with code produced with AI help. By making an agent a contributor that goes through pull requests, policies and approvals, Pulumi follows the same logic as other vendors: autonomy is framed by existing governance. For platform teams, the question will be measuring the quality of proposed changes and deciding which scopes to entrust to the agent. It fits a trend of infrastructure-dedicated agents that other vendors would join in the following months (AWS DevOps Agent in December 2025, Azure SRE Agent in March 2026). At the announcement date, Neo is in public preview: its capabilities and terms of use may still change. ### Takeaway An infrastructure agent built on existing policies: governance already in place becomes the precondition for autonomy.
