What AI is best for writing SQL queries?
ChatGPT Plus, Claude Pro, and DeepSeek V3 all handle SQL generation well. For complex queries with large schemas, Claude's context window handles more schema information in one prompt. For simple to moderate SQL, GPT-4o mini via API is the most cost-effective.
Can AI replace a data analyst?
No, but it accelerates analytical work significantly. AI handles boilerplate code generation, query formatting, and exploratory analysis. Interpretation, business context, and critical judgment still require human expertise.
Is ChatGPT Code Interpreter good for real data analysis?
For exploratory analysis, visualization, and moderate statistical work, yes. It has file size limits and session limitations that make it unsuitable for large production pipelines. Strong for individual analyst use and quick analytical tasks.
