GPTCachegptcache.readthedocs.ioGPTCache is a library for creating a semantic cache of LLM queries, designed to store and reuse responses from large language models to cut API costs and speed up responses. It supports exact and similar (semantic) matching, integrates with LangChain, and can run via a Docker server image to enable cache access across languages and environments. The project is actively developed and documented, with quick-install instructions and examples, though its API may change over time.
