Overview

Caveman is an open-source project that aims to reduce the number of tokens used by AI agents, making them more efficient and cost-effective. It achieves this by using a proxy that shrinks the input tokens read by the agent, resulting in 33.2% fewer input tokens across whole sessions, with the same answers. The project also includes a skill that compresses the output of the agent, reducing the number of tokens used. Caveman has been cited by Adobe Research and has been featured on GitHub Trending, Hacker News, and Product Hunt. The project is licensed under Apache-2.0 and is available on GitHub.
