Developer builds TokenTrimmer to cut Claude Code API costs

By PulseAugur Editorial · [1 sources] ·

A developer created TokenTrimmer, a local proxy tool designed to reduce the cost of using large language models like Claude Code by compressing tool output sent to the API. While synthetic benchmarks show significant compression, real-world usage in Claude Code sessions yielded about a 7.2% saving in lossless mode. The tool prioritizes appending changes to preserve prompt caching, which is crucial for cost-effectiveness, and includes a verification step to ensure no information is lost. A key finding was that replacing repeated lines with references, rather than just compressing them, nearly doubled the savings. AI

IMPACT This tool could significantly reduce operational costs for developers using LLMs with extensive tool output, making AI applications more economically viable.

    What I learned building a lossless token compressor for Claude Code

    <p>In a long Claude Code session, most of what gets sent to the API isn't your prompts. It's tool output: JSON from APIs, command logs, grep results, the same file read twice. And because the whole conversation is resent on every turn, that output is paid for again and again.</p>…
