What it does

Heretic is a unique tool that lets you do what only corporations with access to massive computing power usually do: *Modify,* rather than merely run, language models. It does not perform expensive training; rather, it uses a collection of mathematical techniques to steer behavior based on contrasting example prompts and matching scorers.
