SWE-Gym

Overview

SWE-Gym is a training environment for software-engineering agents built from real codebases, natural-language tasks, executable runtimes, and unit tests. It also treats verifiers as trainable objects rather than assuming the builder is enough.

Why it matters

It matters because coding harnesses need environments that expose real repos, real tests, and real failure surfaces instead of abstract “write some code” theater.

Distinctive trait

Its distinctive trait is pairing software-engineering agent training with verifier training on the same trajectory substrate.
