  CURRENT

  This guide was created by Brex for internal purposes. It's based on lessons learned from researching and creating Large Language Model (LLM) prompts for production use cases. It covers the history around LLMs as well as strategies, guidelines, and safety recommendations for working with and building programmatic systems on top of large language models, like OpenAI's GPT-4.

  This guide from Brex provides battle-tested strategies, guidelines, and safety recommendations for developers and AI practitioners building production-ready systems with Large Language Models (LLMs) like OpenAI's GPT-4. Learn from our internal lessons on crafting effective and safe LLM prompts for real-world use cases.

  ## How is this guide different from LLM libraries or APIs?
  
  This repository is a comprehensive guide and collection of best practices for prompt engineering, not a software library, API, or a specific LLM tool. While it provides strategies for working with models like OpenAI's GPT-4, it does not offer code for interacting with these models directly. Instead, it complements tools like LangChain or LlamaIndex by providing the foundational knowledge needed to use them effectively and safely.
