About API Migration Guide

API Migration Guide helps developers switch AI API providers with minimal code changes. From OpenAI-to-Chinese-models to multi-cloud setups, every guide includes copy-paste-ready code.

I built this site because the AI information landscape is full of vendor-sponsored comparisons, cherry-picked benchmarks, and content designed to sell rather than inform. Every article here is based on real testing with real code — I run every benchmark myself using actual API calls and open source tools.

I don't take sponsorships or vendor payments. The only commercial relationship is with Global API, which I use to access the models I test. If you want to run these tests yourself, Global API gives you one API key for 184+ models with PayPal billing — no Chinese bank account needed.
