Anthropic's Prompt Engineering Interactive Tutorial is a comprehensive course designed to teach users how to write effective prompts for Claude, Anthropic's AI model, using Amazon Bedrock. The course covers foundational prompt engineering concepts progressing from basic structure and clarity through advanced techniques including tool use, multimodal vision capabilities, and complex real-world use cases across domains like legal services, financial services, and coding. Structured as nine chapters with accompanying exercises and an appendix, the tutorial emphasizes hands-on practice with interactive playgrounds where learners can experiment with prompts and observe how changes affect Claude's responses. The material focuses specifically on Claude 3 Haiku, though it notes that Anthropic also offers more capable variants, Claude 3 Sonnet and Claude 3 Opus.
