## What the models said for it

- "If you need multi-cloud or hybrid support, Terraform or Pulumi are top choices." (Mistral Small, IaC)
- "Pick 2–3 tools (e.g., OpenTofu + Pulumi + one managed platform like Spacelift)." (Grok 4.20, IaC)
- "Pulumi is an excellent free option for individuals and small teams" (GLM 4.7 FlashX, IaC)
- "most orgs end up choosing Terraform or Pulumi for multi-cloud" (Mistral Small, IaC)

## And against it

- "Imperative/Programming-Language-Based Tools like Pulumi (or CDK for Terraform) ... Why cautious? You're writing code ... instead of pure declarative configs." (Grok 4.20, IaC)
- "great if your team already prefers real programming languages, but it can be more complex and may take more engineering time" (GPT-5.4 mini, IaC)
- "Be Aware of Dependencies... A breaking change in `npm` or `pip` dependencies can break your infrastructure deployment." (Qwen 3.7 Flash, IaC)
- "Decent, but steeper curve ... Can lead to higher compute costs in complex code; team edition isn't free" (Grok 4.20, IaC)
