Project Title

GPTCache — Semantic Cache for Large Language Models (LLMs) to Reduce API Costs and Improve Speed

Overview

GPTCache is a Python-based library designed to create a semantic cache for storing responses from large language models (LLMs), such as ChatGPT. It aims to slash LLM API costs by up to 10x and boost response speed by 100x. Fully integrated with LangChain and llama_index, GPTCache offers a powerful solution for developers looking to optimize their LLM-based applications.

Key Features

Semantic caching to store and retrieve LLM responses
Integration with LangChain and llama_index for seamless operation
Support for multiple programming languages through Docker image
Automatic installation of additional libraries for extended features
Extensive documentation and community support

Use Cases

Developers using LLMs in applications to reduce API costs and improve response times
Enterprises handling high traffic levels and large volumes of LLM requests
Researchers and data scientists utilizing LLMs for semantic search and analysis

Advantages

Significant reduction in LLM API costs
Dramatic improvement in response speed for LLM services
Easy integration with existing LLM-based applications
Flexibility to use with any language through Docker

Limitations / Considerations

The project is under active development, and the API may change
Support for new API or models is not actively added due to the evolving nature of LLMs
Requires Python 3.8.1 or higher for optimal performance

LangChain: A framework for building LLM applications, with which GPTCache is fully integrated.
llama_index: Another tool for indexing and检索LLMs, also compatible with GPTCache.
OpenAI API: The original API for accessing LLMs like ChatGPT, which GPTCache aims to optimize.
