RSIGym: A Flexible Environment for Recursive Self-Improvement

We introduce RSIGym, an agent-native research environment based on Everything as a Service (EaaS).

Key points

  • Recursive self-improvement requires carrying accepted changes into later improvement cycles, while studying agent-proposed changes also requires substantial research infrastructure.
  • RSIGym exposes training, inference, rollout, evaluation, and sandbox execution through reusable services, with shared budget and permission controls supporting Data, Harness, and Joint improvement tracks.
  • We define RSI-Index as the mean fraction of the remaining performance gap closed across five benchmarks covering software engineering, terminal interaction, mathematics, scientific reasoning, and skill-based tasks.
  • We open-source the full RSIGym codebase and results to support reproducibility and further research.
