New tool 'cartographer' measures code repository token counts for LLMs

By PulseAugur Editorial · [1 sources] ·

The author developed a tool called 'cartographer' to measure the token count of a code repository, addressing the challenge of fitting large codebases into LLM context windows. This tool calculates the ratio between characters on disk and tokens, which varies significantly between different model families and code structures. The primary goal is to provide developers with accurate cost and size estimations for LLM interactions, enabling them to manage context window limitations effectively. AI

IMPACT Provides developers with essential tools for managing LLM costs and context window limitations when working with large codebases.

    Day 03: Your repo does not fit in the context window. Now what?

    <p><em>Handing cartographer files one at a time had been working, so I did the obvious next thing and wrote the four lines that walk a repository and concatenate every source file into one string. Large context windows exist precisely so you can stop being clever about this.</em>…
