Coursera
Machine Learning Specialization (Andrew Ng)
The successor to Andrew Ng's original 2011 ML course — the single most-watched ML course in history (4M+ students). Three courses cover supervised, unsupervised, and reinforcement learning + neural networks from first principles. In 2026, this is still the foundational ML curriculum every serious AI engineer is expected to know. Take this before any LLM-internals course if you don't have classical ML background.

Microsoft Learn
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.
