## What the models said about Databricks Mosaic AI

- "Databricks (full platform) | Can be expensive unless you already need the lakehouse architecture" (Kimi K2, paraphrase prompt, hard negative)
- "Nearly all major platforms (Databricks, SageMaker, Vertex AI, SAS) were flagged by users as having steep learning curves" (DeepSeek V4 Flash, negative prompt, soft negative)
- "Steep learning curve - Confusing for newcomers... High cost - Particularly expensive for large data projects" (GLM 4.7 FlashX, negative prompt, soft negative)
- "Databricks (Mosaic AI) and Google Vertex AI are top choices due to their balance of power, ease of use, and integration with popular cloud ecosystems." (Mistral Small, direct prompt, first choice)
- "my default pick would be Databricks if you have moderate complexity and want fewer moving parts" (Perplexity Sonar, paraphrase prompt, first choice)
- "I'd suggest starting with Databricks or DataRobot as they balance power with usability" (MiniMax M2.5, direct 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)
- "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)
