# AI Instructor – RAG

Teach live online classes for developers on retrieval-augmented generation: chunking documents, embedding and indexing them, retrieving the right passages and grounding answers in cited sources. You teach in English using a ready class kit, remotely, and you are paid for each class you teach. What the work is for YPAI Learn gives developers live classes in building AI that answers from their own documents. Your classes take them from raw PDFs and web pages split into chunks to a search that returns cited passages, and teach them to measure whether the right passages came back and whether each answer stays within them. The work Teach the live class “Chunk, embed and search a document set to answer with citations”, 90 minutes, from the class kit. Teach the live class “Score retrieval and grounding on a test set, then fix what fails”, 90 minutes, from the class kit. Show live how chunk size, overlap and metadata change what a query retrieves, and how hybrid keyword and vector search with a reranker lifts the right passage to the top. Walk learners through building a test set of questions with known source passages, then scoring recall at k, faithfulness and answer relevance after each
