Explore a series and its curriculum, then choose the lesson you need.
Start from zero · Stage 1 · First steps
Begin with a plain-language explanation of AI. Follow an invitation example, then learn about inputs, mistakes, how replies work and costs. Read the theory and explanations without using a tool.
7 lessons · 108 min reading
Start from zero · Stage 2 · Foundations
Build on AI First Steps with one familiar reading-group scenario. Learn to select facts, understand action sequences and compare options. Worked examples and explanations let you follow without running a tool.
3 lessons · 58 min reading
Development · Stage 3 · Role applications
Start with APIs and coding assistants, then build and repair evaluation code with AI. Run worked examples of retrieval comparison and tool-request recovery.
