The Prompt Report is a comprehensive systematic review report focusing on prompting techniques in generative artificial intelligence (GenAI). Through a collaborative effort of humans and machines, it processed 4797 records from multiple databases, extracting 1565 relevant papers. The report presents 58 text-based prompting techniques and complements them with a wide collection of multimodal and multilingual techniques. Its goal is to offer an accessible and implementable directory of prompting techniques and reviews agent-based prompt extensions, including evaluating outputs and designing prompts that promote safety and robustness. Additionally, the report demonstrates the application of prompting techniques in two case studies.
