This whitepaper introduces
prompt engineering, defining it as the process of crafting effective inputs to guide large language models (LLMs) in generating accurate outputs. It explores various
prompting techniques, such as
zero-shot,
one-shot, and
few-shot prompting, which involve providing no, one, or multiple examples to the model. The document also distinguishes between
system,
contextual, and
role prompting, highlighting how each sets the model's overall purpose, provides task-specific details, or assigns a specific persona. Furthermore, it covers advanced methods like
step-back prompting for abstract reasoning,
Chain of Thought (CoT) for breaking down complex problems,
self-consistency for improved accuracy through diverse reasoning paths,
Tree of Thoughts (ToT) for exploring multiple reasoning paths simultaneously, and
ReActfor enabling LLMs to interact with external tools. Finally, the paper offers practical
best practicesfor prompt engineering, including designing with simplicity, being specific about desired outputs, using instructions over constraints, and documenting prompt attempts.
