AI coding agent JSON compressor cuts tokens by 70-90%

A developer has created a tool called SmartCrusher, integrated into the Copium project, designed to significantly reduce token usage in AI coding agents by compressing large JSON arrays. The tool employs statistical relevance scoring, utilizing variance-based change point detection, the Kneedle algorithm for optimal item selection, and BM25 with optional embedding similarity to identify and retain only the most crucial information. Compressed arrays are stored in a cache, allowing the LLM to retrieve omitted data if necessary, with retrieval occurring in less than 3% of cases. AI

IMPACT Reduces token costs for AI agents, potentially enabling more complex operations within context window limits.

RANK_REASON Developer-created tool for optimizing AI agent performance.

    I Built a JSON Compressor Using Change Point Detection and It Outperforms Every Alternative

    <p>Every time your AI coding agent calls a tool, the response is usually a massive JSON array. Think about it. You ask an agent to search your codebase, it returns 500 results. You ask it to list files, it dumps the entire directory tree. You ask it to query a database, it sends …
