Microsoft Azure AI Fundamentals (AI-900) prep
The free prep path for AI-900 — Microsoft's foundational AI certification. Covers Azure AI services (Cognitive Services, Azure OpenAI, vision, language) at a vocabulary-building depth. Free to learn; $99 to take the exam. Worth it for non-engineers at Azure shops who need a cert; skippable for engineers who don't care about Azure-specific signal.

Both free, both updated continuously. Skip the marketing courses (heavy ChatGPT promotion) and go straight to Cookbook for engineering content. The Cookbook is genuinely one of the most-cited free resources in AI engineering in 2026.
