Introduction

Welcome to the prompt engineering guide for large language models (LLMs) on Amazon Bedrock. Amazon Bedrock is Amazon’s service for foundation models (FMs), which offers access to a range of powerful FMs for text and images.

Prompt engineering refers to the practice of optimizing textual input to LLMs to obtain desired responses. Prompting helps LLMs perform a wide variety of tasks, including classification, question answering, code generation, creative writing, and more. The quality of prompts that you provide to LLMs can impact the quality of their responses. These guidelines provide you with all the necessary information to get started with prompt engineering. It also covers tools to help you find the best possible prompt format for your use case when using LLMs on Amazon Bedrock.

Whether you’re a beginner in the world of generative AI and language models, or an expert with previous experience, these guidelines can help you optimize your prompts for Amazon Bedrock text models. Experienced users can skip to the General Guidelines for Amazon Bedrock LLM Users or Prompt Templates and Examples for Amazon Bedrock Text Models sections.

Note

All examples in this doc are obtained via API calls. The response may vary due to the stochastic nature of the LLM generation process. If not otherwise specified, the prompts are written by employees of AWS.

Disclaimer: The examples in this document use the current text models available within Amazon Bedrock. Also, this document is for general prompting guidelines. For model-specific guides, refer to their respective docs on Amazon Bedrock. This document provides a starting point. While the following example responses are generated using specific models on Amazon Bedrock, you can use other models in Amazon Bedrock to get results as well. The results may differ between models as each model has its own performance characteristics. The output that you generate using AI services is your content. Due to the nature of machine learning, output may not be unique across customers and the services may generate the same or similar results across customers.
