The Return of Recursion: How 5M-Parameter Models Are Outperforming Frontier LLMs on Reasoning in 2026





TL;DR Summary



Tiny recursive models with 5-7 million parameters are achieving state-of-the-art on deterministic reasoning tasks that frontier LLMs score 0% on — including Sudoku-Extreme, ARC-AGI puzzles, and maze navigation
The key...
