## What the models said about Nutanix AHV

- "Per-node software licensing is expensive for small deployments." (DeepSeek V4 Flash, budget prompt, hard negative)
- "You generally cannot buy just the hypervisor license cheaply anymore." (Qwen 3.7 Flash, negative prompt, soft negative)
- "Good for HCI, but cost + vendor lock-in needs evaluation." (DeepSeek V4 Flash, negative prompt, soft negative)
- "If you want the safest default recommendation for a mid-sized B2B company replacing VMware, I'd usually pick Nutanix Cloud Platform with AHV." (GPT-5.4 mini, paraphrase prompt, first choice)
- "my default recommendation would be Nutanix AHV if you want the closest commercial replacement to VMware" (Perplexity Sonar, paraphrase prompt, first choice)
- "If you want the closest "VMware-like" experience with enterprise support: Go with Nutanix AHV" (MiniMax M2.5, paraphrase prompt, first choice)

## What the models said about VMware vSphere

- "Avoid unless necessary: VMware vSphere — the cost increases post-Broadcom acquisition make it difficult to justify for mid-market budgets" (Kimi K2, direct prompt, hard negative)
- "Avoid for new or ongoing production deployments unless you have a specific support arrangement." (GPT-6 Luna, negative prompt, hard negative)
- "Why NOT VMware for Limited Budgets? ... prohibitively expensive" (Kimi K2, budget prompt, hard negative)
- "Industry leader in enterprise virtualization... For enterprises: VMware ESXi and Microsoft Hyper-V are the most feature-rich and widely supported." (Mistral Small, comparative prompt, first choice)
- "The Market Leader: VMware (vSphere / ESXi) ... Choose VMware if money is no object and you need the absolute most robust, feature-rich toolset" (Qwen 3.7 Flash, comparative prompt, first choice)
- "Despite recent licensing controversies, VMware remains the industry benchmark for virtualization performance, security, and high availability." (Gemini 3.5 Flash, comparative prompt, first choice)
