Token Efficiency vs Cognitive Efficiency: Choosing IaC for AI Agents
The Pulumi blog benchmark compares Terraform HCL and Pulumi TypeScript when generated by Claude Opus 4.6 and GPT‑5.2‑Codex. HCL consistently uses 21‑33% fewer tokens for initial resource creation, lowering raw generation cost. However, Pulumi’s TypeScript refactoring achieves higher deployable success rates and eliminates repair cycles, especially with Claude Opus, resulting in the lowest total pipeline cost. GPT‑5.2‑Codex is cheaper on raw tokens but fails Terraform refactoring, highlighting a trade‑off between token efficiency and cognitive efficiency.
