Default recommendation
ChatGPT Plus at $20/month is the most complete data-analysis subscription thanks to built-in code execution. For very large schemas and reports, Claude Pro at $20/month with a 1M context handles more in one session; for pipelines, call DeepSeek V4 Pro or GPT-5.4 mini directly.

Frequently Asked Questions
What AI is best for writing SQL queries?
ChatGPT Plus, Claude Pro and DeepSeek V4 Pro all handle SQL well. For large schemas, Claude's 1M context fits more schema in one prompt. For simple to moderate SQL at scale, GPT-5.4 mini via API ($0.75 in / $4.50 out per 1M tokens) is the most cost-effective.
Can AI replace a data analyst?
No, but it accelerates the work. AI handles boilerplate code, query formatting and exploratory analysis; interpretation, business context and judgement still need a person.
Is ChatGPT's data analysis good for real work?
For exploratory analysis, visualisation and moderate statistics, yes. File-size and session limits make it unsuitable for production pipelines; use the API for those.
What does a data pipeline cost on the API?
At 1M input and 200K output tokens a month, GPT-5.4 mini is about $1.65, DeepSeek V4 Pro about $2.11 at peak or $1.06 off-peak, and Gemini 3.1 Pro about $4.4. Batch endpoints at roughly half list suit overnight jobs, and DeepSeek's off-peak hours do the same for its API. DeepSeek pricing checked 2026-10-27 at api-docs.deepseek.com.
