AI ExpertWhat AI Expert is
AI Expert is a free training and certification site for AI engineers. Seven programs (LLM Foundations, Context Engineering, Production RAG, Agents and Orchestration, Evaluation and Observability, AI Security and Safety, LLMOps and Architecture) cover what separates a demo from a production system.
Each module has a short, sourced briefing, spaced-repetition drills, 'demo or production?' judgement calls and a written production scenario scored on a rubric. In-browser labs let learners feel token costs, chunking, hybrid retrieval and judge calibration; 18 real incident files show what broke in shipped AI products. Final exams issue certificates with public verification codes. AI Expert is its own authority, not an accredited body, and the certificates say so.
Who it's for: Software engineers, data scientists and ML engineers moving into AI product work, and tech leads who review AI designs
