blog post · Story page

LangChain put a model router inside Open SWE's harness and reports a 64% cut in median cost per coding task with no measurable drop in quality, then shows how to build your own.

In plain words

  • LangChain reports making automated coding cheaper without a measurable drop in quality.
  • A built-in selector chooses which artificial intelligence system handles the coding work.
  • Developers can use the guide to build a similar selector for their own coding tools.
