## The Recursion Revolution: Meta^n's Core Innovation

Existing systems that introduce a meta-level tend to fix that level, while self-editing mechanisms require retaining untouched components for stability, typically limiting meta-depth to around two layers.

The breakthrough presented by Meta$^n$ lies in its approach: it keeps the meta-operation, denoted as $Ω$, fixed and instead recurses on its input.

This fixed $Ω$ operation is repeatedly applied to its own products, analyzing the traces of the solver stack and the code that generated them to produce the next layer as a strategic pre-process and a library of callable helpers.

## Achieving Unprecedented Depth and Performance

Because $Ω$ remains constant, it inherently avoids destabilizing the system, a critical advantage over prior self-improving architectures.

Furthermore, as the input to $Ω$ strictly grows with each recursive step, every subsequent layer benefits from a higher vantage point, fostering deeper reasoning capabilities.

The depth of the Meta$^n$ LLM agent is not predetermined but dynamically set by convergence, with an evolutionary archive optimizing layer chains.

Across two distinct backbone architectures, Meta$^n$ significantly outperforms existing self-improving agents on all eight benchmark families evaluated.

## Dominance in Rigorous Benchmarking

The most striking demonstration of Meta$^n$'s efficacy is on the ARC-AGI-2 benchmark, specifically designed to resist skill memorization, where it uniquely achieves a score above zero.

Ablation studies reveal that a substantial portion of the performance gains stems from the conditioning passed between successive layers.

Interestingly, distinct layer roles emerge organically as depth increases, even without explicit prompting to define them.
