Study for AI-901 one lesson and one question at a time. Learn about generative AI, agents and choosing AI capabilities, then return to the questions you missed. LEARN, THEN CHECK YOUR UNDERSTANDING Follow lessons with knowledge checks and read the explanations after answering. Diagrams and short columns connect concepts with implementation. What makes an agent different from a model? How do you extract information from documents? Work through questions like these as you study. MAKE SENSE OF SIMILAR CONCEPTS Compare easily confused pairs and think through service-selection scenarios. Revisit key ideas with flashcards and a glossary. REVIEW YOUR MISTAKES Retry missed questions from your answer history. Return to bookmarked questions and drill cards when you need a refresher. CHECK READINESS WITH MOCK EXAMS Practice with four mock exams and chapter tests. In timed mode, track the remaining time, then review your results and explanations. These are independently created practice questions, not actual exam questions. START FREE. EXPAND WITH PREMIUM. Start with lessons, knowledge checks and the first mock exam. A one-time Premium purchase unlocks the remaining mock exams and paid practice content, and removes ads. It is not a subscription. Check the in-app purchase screen for the price in your region. STUDY TOPICS • AI concepts and responsible AI • Models, workloads and deployment choices • Generative AI apps, single agents, prompts and RAG • Text analysis, speech recognition and speech synthesis • Vision, document processing and information extraction Study Foundry implementation concepts and how to read Python code.
