why use many token when few do trick
Caveman is an innovative open-source tool designed for developers and AI practitioners seeking to optimize their interaction with large language models and AI providers. By wrapping calls to models like Claude Code, Codex, Hermes, and others within a local proxy, Caveman significantly reduces token usage through intelligent compression of logs, tool outputs, and files before each provider call. Its unique approach enables users to achieve around 33% fewer input tokens in benchmark tests, all while maintaining high correctness checks. Additionally, Caveman can run existing agent skills with approximately 70% fewer tokens by loading text as images, making it a versatile and efficient solution for token-conscious AI workflows. Built on a robust open-source ecosystem with over 97,000 GitHub stars, Caveman appeals to developers looking to streamline and cost-optimize their AI integrations.
Pros
- Reduces token consumption by up to 33% in benchmarks
- Supports multiple AI providers like Claude, Codex, and Hermes
- Open-source with a large community backing
- Can run existing agent skills with 70% fewer tokens
- Flexible local proxy architecture for customization
Cons
- May require technical expertise to implement and customize
- Limited information on formal support or enterprise features
- Performance depends on local hardware and setup
Best for
- • Optimizing large language model prompts to reduce costs
- • Integrating multiple AI providers in a unified workflow
- • Running AI agents more efficiently with fewer tokens
- • Compressing logs and outputs for better data management
Pricing: As an open-source project, Caveman is free to use. Additional costs may stem from the need for local infrastructure or hardware, but there are no subscription fees or paid plans associated with the tool itself.
