TL;DR LLMs charge per token, and large codebases generate enormous token bills - especially when AI agents re-ingest the same context repeatedly. CoreStory transforms your codebase into a persistent Code Intelligence Model (CIM), giving AI agents structured, targeted context instead of raw code. In a real-world evaluation, Claude Code paired with CoreStory used 73% fewer input tokens, ran in half the time, and cost 67% less - while delivering better results. This post explains why that happens and how to replicate it.
