AI coding sessions waste 97.6% of tokens on noise, analysis finds

A developer analyzed 4,788 AI coding sessions and found that 97.6% of tokens processed were wasted on noise rather than actual coding or debugging tasks. This noise primarily comes from repetitive test outputs, verbose build logs, package manager messages, and Git status updates, which are designed for human readability but are inefficient for AI context windows. The developer suggests filtering these outputs to significantly reduce token consumption and costs, noting that stack traces are an exception as they are information-dense and crucial for debugging. AI

    I Analyzed 4,788 AI Coding Sessions — Here's Where Your Tokens Actually Go

    <p>Last month I started tracking every command I ran through Claude Code, Cursor, and Aider. After 4,788 commands and 355 million tokens, I found something shocking:</p> <p>97.6% of my tokens were wasted on noise.</p> <p>Not on actual coding. Not on debugging. On repetitive test …
