The paper introduces ParetoRSI-Gym, a framework for evaluating recursive self‑improvement (RSI) in language models across multiple domains—math, code, finance, medicine, and science—by having agents iteratively search for, curate, and train on data while keeping the base model, toolset, and training pipeline fixed. Experiments with three agent systems and three base models show that the best system (Claude Code with Opus‑5) improves generalization scores by an average of 9.2% relative to the starting model, with domain‑specific gains up to 63%. The study highlights that both the harness and the agent’s data‑selection strategy significantly influence outcomes, underscoring the need for realistic multi‑domain evaluation of RSI systems.

Interlock is a framework that transforms long‑horizon tasks into typed completion graphs, linking evidence, decisions, and required effects through grounding, coupling, and realization edges. It compiles these graphs into a resettable workspace, a public request, and an evaluation rubric, and uses source‑coverage, public‑input, and agent‑as‑judge reviews to ensure that all mandatory requirements are met. Fine‑tuning Qwen3.6 backbones on Interlock‑generated trajectories improves pass rates on AutomationBench, JobBench, and Harvey LAB, showing that the synthesized experience benefits external task environments.

The paper introduces Belief-Calibrated Optimization (BCO), a method that records and updates a persistent in‑context document representing an agent’s belief about how the environment responds to edits. By continually revising this world model as new candidates are evaluated, BCO improves the performance of frozen LLM agents across five benchmarks, outperforming a control lacking the world model. An offline ablation shows that the document’s content provides reusable, accurate predictions of environmental responses, beyond mere form.
