## What the models said about Google Cloud SQL

- "extended support is paid, and Cloud SQL automatically enrolls EOL-version instances. Check the exact engine version and upgrade dates before committing." (GPT-6 Luna, negative prompt, soft negative)
- "it has the same class of cautions as other DBaaS offerings: you should check pricing, scaling model, maintenance control..." (Perplexity Sonar, negative prompt, soft negative)
- "Less ideal for global/multi-region strong consistency writes.<br>- Scaling not as elastic for extreme loads." (Grok 4.1 Fast, negative prompt, soft negative)
- "I'd recommend considering Amazon RDS (Relational Database Service) or Google Cloud SQL as your primary options" (GLM 4.7 FlashX, paraphrase prompt, first choice)
- "The top managed relational database services are Amazon RDS, Google Cloud SQL, Azure SQL Database" (Perplexity Sonar, comparative prompt, first choice)
- "Amazon RDS or Google Cloud SQL offer the best balance of features, scalability, and reliability" (Claude Haiku 4.5, paraphrase prompt, first choice)

## What the models said about Azure SQL Database

- "Azure SQL Database, while generally robust, has resource caps and licensing implications that require careful planning" (Mistral Small, negative prompt, soft negative)
- "Standard Azure SQL Database strips out many legacy features (like SSIS, SQL Agent jobs, and certain system views)" (Qwen 3.7 Flash, negative prompt, soft negative)
- "These are solid managed services, but Azure's own guidance warns not to choose solely by engine compatibility" (Perplexity Sonar, negative prompt, soft negative)
- "Azure SQL Database is a fully managed, intelligent relational database service built on the Microsoft SQL Server engine" (Perplexity Sonar, comparative prompt, first choice)
- "Amazon RDS or Azure SQL Database would be the safest bets depending on your existing tech stack" (MiniMax M2.5, paraphrase prompt, first choice)
- "Best for Microsoft Shops ... Lower first-choice share (4%) in general recommendations, but very strong within Microsoft-centric environments" (Kimi K2, direct prompt, alternative)
