Anthropic's interactive tutorial aims to provide comprehensive step-by-step guidance on building optimal prompts within Claude. The tutorial consists of nine chapters, each accompanied by exercises and an appendix featuring more advanced methods. It utilizes Anthropic's smallest, fastest, and most cost-effective model, Claude 3 Haiku, along with the more intelligent Claude 3 Sonnet and Claude 3 Opus models. The tutorial is also available on Google Sheets using Anthropic's Claude for Sheets extension, which is recommended for its user-friendly interface.
