The development
RSI-Anything extends recursive self-improvement beyond human feedback by coupling predictive world models with adaptive policy learning across domains. The framework addresses a core scaling bottleneck: as agents improve, external validation becomes expensive and model predictions drift. By using learned world models to guide both action selection and training-data curation, the system achieves measurable gains in code repair (26.3% to 31.2% success) and other computational tasks. This work signals a shift toward self-directed agent improvement, reducing reliance on costly external signals and enabling continuous refinement in open-ended problem spaces.

RSI-Anything's core contribution is decoupling improvement from external validation by using learned world models to both select actions and filter training data. The 5-point gain in code repair success is modest, but the mechanism matters: the system addresses prediction drift, a problem that worsens as agents improve and ground-truth feedback becomes scarce.
This work sits directly downstream of two prior pieces. The JANUS framework (Oct 9) introduced co-evolving world models to predict experiment outcomes before execution, shifting research from execution-constrained to prediction-constrained. RSI-Anything generalizes that insight across domains by making the world model do double duty: outcome prediction and data curation. Meanwhile, the verifier co-evolution paper (Oct 8) tackled the complementary problem of reliable grading when ground truth vanishes. Together, these three papers form a coherent stack for self-improving systems: predict outcomes, grade progress reliably, and use both to reduce dependence on external signals.
If RSI-Anything's gains replicate on held-out domains beyond code repair (e.g., math reasoning or robotics simulation) without retraining the world model, that confirms the framework generalizes. If the approach fails on tasks where world model accuracy drops below 70%, that signals the method is brittle to prediction quality and not a universal scaling solution.

World models accelerate autonomous research by predicting experiment value before execution
JANUS addresses a fundamental bottleneck in autonomous AI research: the feedback delay that slows hypothesis validation cycles. Rather than reactive trial-and-error, the framework deploys a co-evolving world model that predicts outcomes before execution, scoring candidate experiments by forecasting value improvement and exploration utility. This shifts autonomous research from execution-constrained to prediction-constrained, allowing agents to filter…
