AI systems increasingly participate in their own improvement: revising their outputs, adapting their own harnesses during deployment, training on data they generate, and, increasingly, conducting AI research itself. This literature is described under a vocabulary ("self-refine," "self-reward," "self-play," "self-evolve") that conflates fundamentally different ambitions.

arXiv:2607. 05297v1 Announce Type: new Abstract: Recent LLM agents tackle increasingly long-horizon, open-ended tasks, and external skills, reusable procedural knowledge supplied to the agent, further extend this capability.
Meta$^n$ is a recursive self‑improvement framework for large language models that keeps a fixed meta‑operation Ω and repeatedly applies it to its own outputs, creating deeper layers that reason from higher perspectives. By avoiding changes to the meta‑operation, the system remains stable while the input grows, allowing depth to emerge through convergence and evolutionary search. Experiments on two backbone models show Meta$^n$ surpasses prior self‑improving agents across eight benchmark families, notably achieving positive scores on the ARC‑AGI‑2 benchmark designed to resist skill memorization.
The paper introduces Regularized Recursive Self-Improvement of Agent Harnesses (RRSI), a method that applies regularization principles to the iterative editing of an LLM agent’s harness—prompts, control flow, tooling, memory, and context management. RRSI limits the number of edits per candidate, encourages novel trajectories, and uses a critic and pruner to filter out benchmark‑specific or ineffective changes, thereby favoring reusable agent mechanisms. Experiments on eight benchmarks show RRSI improves performance by up to 14.1 points on the training split and 4.7 points on out‑of‑distribution tests, while reducing policy token usage by 30% compared to unregularized evolution.
