“Preferred starters: Terraform (or OpenTofu, its open-source fork—use if concerned about HashiCorp's licensing shifts post-2023) for declarative multi-cloud.” Grok 4.20 · negative prompt · first choice
“For most budget-constrained companies, Terraform offers the best balance of features, flexibility, and cost (free), making it the industry standard.” Claude Haiku 4.5 · budget prompt · first choice

“Why avoid for IaC: Weak state-tracking engines compared to purpose-built IaC tools.” Gemini 3.5 Flash · negative prompt · hard negative
“Ansible, Chef, Salt, and Puppet for primary provisioning. These are primarily configuration-management tools, not infrastructure-provisioning engines.” Perplexity Sonar · negative prompt · soft negative

“For a budget-constrained company, Ansible is the safest bet if you need a free, open-source solution” GLM 4.7 FlashX · budget prompt · first choice
“Ansible if your focus is more on app deployment/config than pure infrastructure ... less ideal for complex cloud resource graphs” Grok 4.20 · paraphrase prompt · alternative
