## What the models said about Amazon SageMaker

- "Some AI models recommend avoiding this platform if you are a small team, a startup, or just starting out." (Llama 4 Maverick, negative prompt, hard negative)
- "models explicitly advising to avoid it unless you have significant resources or a large team" (Mistral Small, negative prompt, hard negative)
- "Avoid enterprise-scale platforms like SageMaker, Dataiku, or DataRobot — they're overkill" (DeepSeek V4 Flash, negative prompt, hard negative)
- "AWS SageMaker and Azure Machine Learning are the most practical managed choices for companies that are already standardized on one cloud." (Muse Glimmer 30B, paraphrase prompt, first choice)
- "Market Share: ~34% (leader) ... Primary Strength: Broadest ML feature set and deepest AWS integration" (Kimi K2, comparative 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 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)
