GPTCache is a Python library for building a semantic cache that stores and retrieves LLM responses based on embedding similarity, reducing API costs and latency. It integrates with LangChain and llama_index and offers a Docker server usable from any language.
Use cases
- cache LLM API responses to cut costs
- speed up chatbot responses with semantic caching
- reduce duplicate OpenAI API calls
- add a memcache layer for AIGC applications
- integrate semantic caching into LangChain pipelines
When to choose
- your LLM app has high traffic with repeated or similar queries
- you want to lower OpenAI/LLM API bills and latency
- you use LangChain or llama_index and want drop-in caching
When to avoid
- you need support for brand-new LLM APIs (no longer added)
- you need a stable, unchanging API (it may change)
- your queries are mostly unique with little semantic overlap
