In plain words: A fixed rewriting step re-reads the solver's traces and code, writes a new strategy plus helper tools, then repeats on its own output until it stops improving. It beats earlier self-improving agents on all eight test families, alone scoring above zero on ARC-AGI-2.

Abstract · Meta$^n$: Recursive Self-Improvement through Emergent Depth

Self-improving LLM agents refine answers, not the process that produces those answers. Systems that add a meta-level hold that level fixed, and those that edit themselves must leave part of their own editing machinery untouched to stay stable, capping the meta-depth they realize at roughly two. We present Meta$^n$, which keeps the meta-operation fixed and recurses on its input instead. That operation, $Ω$, is applied repeatedly to its own products, reading the traces of the solver stack below together with the code that produced them, then writing the next layer as a strategic pre-process and a library of callable helpers. Because $Ω$ never changes, it cannot destabilize the system, and because its input strictly grows, each layer reasons from a higher vantage than the last. Depth is set by convergence rather than fixed in advance, and an evolutionary archive searches over layer chains. Across two backbones, Meta$^n$ outperforms prior self-improving agents on all eight benchmark families. The sharpest case is ARC-AGI-2, built to resist skill memorization, where it alone scores above zero. Ablations indicate that most of the gain from recursion comes from the conditioning each layer passes to the next, and distinct layer roles emerge with depth although no prompt prescribes them.

One thing I'd be extremely interested in is a system that can improve itself at specific tasks or types of task. For example, many of the available LLMs don't excel at the type of writing I like, and rather than having to curate thousands of examples of a very particular and extremely rare niche, it would be nice to be able to describe what I value about just a few examples, and let the model improve on its own until it reaches a competitive level.

I'm talking about a hypothetical future model that is somehow able to model the type of curiosity and drive to genuinely improve of some real people. I don't think we've achieved models being able to innately tell whether they've improved the same way a person can. I can tell whether I've improved at art, at writing, at production, etc. without needing to be graded by a higher authority. I'd still like to check in and let the model know if it's been getting it right, but I really hope this sort of mostly unsupervised learning happens within my lifetime, because it'd be really cool.

Watch out for misuse of technical jargon. Big red flag. Remember those articles on arxiv claiming to solve reimann that no one can understand because of the disconnected writing style full of technical terms?
