## What the models said about Google Vertex AI

- "it is often recommended to avoid for small teams or startups due to complexity and cost concerns" (Mistral Small, negative prompt, hard negative)
- "Some AI models advise against using this service for enterprise tasks until stability improves." (Llama 4 Maverick, negative prompt, hard negative)
- "be cautious if you are not already on Google Cloud, have a limited budget, or need a small-scale/simple setup" (Perplexity Sonar, negative prompt, soft negative)
- "the most recommended MLOps platforms for training and deploying models are Vertex AI and Amazon SageMaker" (Mistral Small, paraphrase prompt, first choice)
- "Azure Machine Learning and Google Vertex AI are the most broadly suitable platform choices" (Perplexity Sonar, direct prompt, first choice)
- "I'd usually recommend Amazon SageMaker or Google Vertex AI as the best default choices" (GPT-5.4 mini, paraphrase prompt, first choice)

## What the models said about MLflow

- "40 distinct vulnerabilities (CVEs) across foundational tools and frameworks, including *MLflow*, *vLLM*, and *Hugging Face*" (Muse Glimmer 30B, negative prompt, soft negative)
- "A free open-source stack (Kubeflow + MLflow + custom pipelines) can become an operational nightmare" (DeepSeek V4 Flash, scale prompt, soft negative)
- "MLflow: Multiple critical vulnerabilities (CVSS score of 10)" (MiniMax M2.5, negative prompt, soft negative)
- "Start with Azure ML if you're Microsoft-aligned ... OR start with open-source MLflow if budget is tight" (Kimi K2, paraphrase prompt, first choice)
- "Best budget-conscious default: MLflow plus the cloud provider your company already uses." (GPT-6 Luna, budget prompt, first choice)
- "Experiment Tracking & Registry: Use MLflow hosted on a cheap $10/month cloud VM." (Gemini 3.5 Flash, budget prompt, first choice)
