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 implementing a 'caveman' voice that simplifies the language used by the agents, reducing the number of tokens required to convey the same information. The project includes several features, such as 'Say less', 'Read less', 'Auto', and 'Blocks', which work together to minimize token usage. 'Say less' simplifies the agent's answers, 'Read less' compresses the input data, 'Auto' optimizes the model and effort used for each task, and 'Blocks' keeps track of scripts written by the agent, reducing repetition. Caveman is designed to work with various AI agents, including Claude, Codex, and OpenCode, and can be installed using a simple command. The project also includes a cloud version, Caveman Cloud, which provides additional features such as observability, evaluations, and autopilot for agent development.
