Tiny 7M-parameter model outperforms large language models on abstract-reasoning benchmarks
A Samsung researcher's recursive network claims higher ARC-AGI scores than several large language models with a fraction of the parameters, challenging the assumption that scale is the only path to reasoning.

A researcher at Samsung’s AI lab in Montreal has published a paper describing a 7-million-parameter neural network that outperforms several large language models on abstract reasoning benchmarks. The Tiny Recursive Model (TRM), detailed in a paper on arXiv, achieves 45% accuracy on ARC-AGI-1 and 8% on ARC-AGI-2, scores that surpass those of DeepSeek-R1, OpenAI’s o3-mini, and Google’s Gemini 2.5 Pro, according to the paper.
TRM works by recursively refining its answers. It maintains two short-term memories: one for the current solution and another as a scratchpad for intermediate steps. At each iteration, it reviews the problem, its current answer, and its notes, then updates its output. An adaptive halting mechanism stops the process when improvements plateau. The approach uses a single two-layer network, in contrast to the Hierarchical Reasoning Model (HRM) that inspired it.
On other benchmarks, TRM scored 87% on Sudoku-Extreme and 85% on Maze-Hard. In an X post, Jolicoeur-Martineau says the model trains for under $500 using four H-100 GPUs over about two days. While TRM excels at grid-based puzzles, it is not designed for open-ended tasks like conversation or image generation. The paper suggests that recursive reasoning may offer a path to strong performance on structured problems without massive parameter counts.
The record
Announced the paper on X, linking to a blog post and code, and highlighted the model's benchmark results.
Noted that training the model cost under $500, using four H-100 GPUs for about two days.

TRM took first place in the ARC Prize 2025 paper awards in December 2025, and tiny recursive models became a research thread of their own, with follow-up papers building on the architecture into 2026.
