Paper summary: Less is More: Recursive Reasoning with Tiny Networks

Tiny Recursive Model, a single 2-layer network with 7M parameters that repeatedly refines its answer, reports 45% on ARC-AGI-1 and 8% on ARC-AGI-2, above many large LLMs on these puzzles.

Problem

The Hierarchical Reasoning Model (HRM) used two small networks recursing at different frequencies, trained on about 1,000 examples, and beat LLMs on Sudoku, Maze and ARC-AGI. The author notes HRM was not well understood and possibly suboptimal.

Method

Tiny Recursive Model (TRM) keeps the core idea, recursion, and drops the rest: a single tiny network with only 2 layers applied repeatedly to refine its reasoning state and answer.

Key results

From the abstract: with 7M parameters, TRM reaches 45% test accuracy on ARC-AGI-1 and 8% on ARC-AGI-2. That’s higher than most LLMs, including DeepSeek R1, o3-mini and Gemini 2.5 Pro, with less than 0.01% of their parameters, and better generalisation than HRM.

Limitations

There’s no dedicated limitations section in the extracted text. TRM is a puzzle-solving network, not a general-purpose language model, so the comparison with LLMs is on these puzzle benchmarks only.
