## What the models said for it

- "If your developers are already writing TypeScript/Python, Pulumi or AWS CDK can flatten the learning curve significantly." (Kimi K2, IaC)
- "The best infrastructure as code tools in 2026 are Pulumi, Terraform, OpenTofu... Pulumi offers a distinct approach" (Claude Haiku 4.5, IaC)
- "Pulumi | Strong multi-language support, excellent secrets engine, and great developer UX." (Gemini 3.5 Flash, IaC)
- "For multi-cloud provisioning, Terraform, Pulumi, and Crossplane are top choices." (Mistral Small, IaC)

## And against it

- "Pulumi's free tier is limited: The free Individual tier supports only 1 user, making it impractical for teams without paying." (DeepSeek V4 Flash, IaC)
- "Team tier is paid (~$40–$150+/user/month); higher learning curve for ops teams not comfortable with programming." (GLM 4.7 FlashX, IaC)
- "Pitfalls: Less mature ecosystem/modules than Terraform, "footguns" from general-purpose languages" (Grok 4.1 Fast, IaC)
- "it can be more complex and less budget-friendly operationally" (GPT-5.4 mini, IaC)
