Which Microsoft AI Certification: The Forks Between AI-103, AI-500, AB-620, and AB-100
Across Microsoft's four AI/agent certifications there are two hard prerequisites: AI-500 requires AI-103, and AB-100 requires any one associate on its list. The rest is positioning. Three forks decide it: whether you write Python (AI-103/AI-500 vs AB-620), whether you build or judge (AB-100 vs the rest), and whether you can actually start today — AI-500's four official learning paths currently 404, AB-620 has no practice test, AB-100 has a free one. For readers who prefer Chinese there is a fourth fork: AI-103, AB-620, and AB-100 offer Traditional Chinese, and only AI-500 is English only. All four cost $165 in the US ($83 in Taiwan), expire after one year, and renew free but only inside a six-month window.
