Coding

Environments that train and evaluate models on real software engineering: resolving issues in production repositories, writing and reviewing pull requests, debugging failing test suites, and shipping features end-to-end. Coding is the most mature RL environment category: benchmarks like SWE-bench proved that verifiable rewards from test suites scale, and frontier labs now buy coding environments by the thousand.
