Key positions and views

Standard transformer-based LLMs are architecturally incapable of solving problems that require more sequential reasoning steps than they have layers.

Small, parameter-efficient recursive models like the 7-million-parameter TRM can decisively outperform massive, trillion-parameter LLMs on complex reasoning benchmarks.

The future of advanced AI lies not in scaling a single architecture, but in hybrid systems that combine the broad knowledge of LLMs with the deep, focused reasoning of compact recursive models.

Advances in training methodology, specifically the ability to effectively backpropagate through deep recursive steps, are the most critical factor in unlocking the performance of recursive models.

The 'outer refinement loop' was the single most important architectural innovation responsible for the high performance of the Hierarchical Reasoning Model (HRM).

Points of consensus

▶Recursive models like HRM and TRM demonstrate superior performance over large language models on specific, complex reasoning benchmarks such as ArcPrize 1.May 2026

▶Standard feed-forward transformer architectures have inherent limitations, making them unable to solve problems that require more sequential steps than the number of layers in the model.May 2026

▶Model efficiency is a key advantage of recursive architectures, with models as small as 7 million parameters outperforming trillion-parameter LLMs on certain tasks.May 2026

▶Innovations in training methods, such as DEQ-inspired techniques in HRM and full backpropagation through latent steps in TRM, have been critical to the success of recursive reasoning models.May 2026

Points of debate

▶While acknowledging that LLMs are Turing-complete at test time with methods like Chain of Thought, Chauvard argues they are fundamentally incapable of solving certain problems that smaller recursive models can, presenting a nuanced view on LLM capabilities.May 2026

▶There is a clear evolution in architectural approach, from the three-loop, dual-network Hierarchical Reasoning Model (HRM) to the more streamlined and efficient single, weight-shared network of the Tiny Recursive Model (TRM).May 2026

▶Chauvard contrasts the historical failure of backpropagation through time in RNNs due to error accumulation with the recent success of new backpropagation strategies in HRM and TRM, which have been key to their performance.May 2026

▶Within the HRM architecture, Chauvard highlights that analysis by a colleague identified the 'outer refinement loop' as the primary driver of its high performance, suggesting an internal discovery process about which components were most critical.May 2026

Key themes

▶The Limits of Scale in TransformersMay 2026

Chauvard consistently argues that simply increasing the size and training data of LLMs is insufficient for certain classes of problems. He posits that transformer architectures have a fundamental ceiling on sequential reasoning, as an N-layer model cannot perform an algorithm requiring more than N steps, like sorting a list of N+1 items in a single pass.

This challenges the dominant 'bigger is better' investment thesis in AI, suggesting that architectural innovation, rather than just scale, will be necessary for the next leap in AI capabilities, creating opportunities for companies focused on novel model designs.

▶Recursion as the Next Scaling LawMay 2026

The central thesis of Chauvard's commentary is that recursion is the key to unlocking superior reasoning in AI. He champions models like HRM and TRM, which use iterative, recursive processes to solve complex problems that LLMs fail on, demonstrating that a different scaling paradigm based on computational depth can be more effective than one based on parameter count.

Analysts should monitor progress in recursive and algorithmic models, as they represent a potential paradigm shift where smaller, more efficient, and specialized reasoning engines could become critical, high-value components in the broader AI ecosystem.

▶Architectural Evolution from HRM to TRMMay 2026

Chauvard details a rapid, iterative improvement from the Hierarchical Reasoning Model (HRM) to the Tiny Recursive Model (TRM). This evolution involved significant parameter reduction (27M to 7M), architectural simplification (from two networks to one weight-shared network), and a more advanced backpropagation technique, leading to a substantial performance increase on the ARC-Prize benchmark (70% to 87%).

The high velocity of improvement between HRM and TRM indicates that this niche area of AI research is on a steep trajectory, signaling a potentially disruptive technology curve that could quickly produce commercially viable applications.

▶A Hybrid Future for AI SystemsMay 2026

Chauvard predicts that the most significant future breakthroughs will come from combining the strengths of different AI architectures. He envisions a hybrid system where large language models provide a broad knowledge base and create a rich latent space, within which smaller, efficient recursive models like TRM perform deep, focused reasoning.

This suggests the future AI market may not be a winner-take-all scenario for foundational model providers, but rather an ecosystem where specialized, high-performance reasoning modules are integrated as essential add-ons, creating a new market for 'AI reasoning plugins'.

Changes over time

Circa 2016

Chauvard notes this period as the peak of interest in Recurrent Neural Networks (RNNs), which ultimately struggled with training issues like error accumulation during backpropagation through time.

HRM Development

The 27-million-parameter Hierarchical Reasoning Model (HRM) is introduced, achieving 70% accuracy on ArcPrize 1. It uses a novel three-loop architecture and a DEQ-inspired training method to overcome the limitations of older RNNs.

HRM Analysis

Following its development, analysis by Constantine at François Challet's company reveals that the 'outer refinement loop' is the primary component responsible for HRM's high performance.

TRM Breakthrough

The Tiny Recursive Model (TRM) is developed as an improvement on HRM. By reducing parameters to 7 million, using a single weight-shared network, and enabling backpropagation through the entire latent step, it boosts performance on ARC-Prize 1 to 87%.

Future Outlook

Chauvard articulates his forward-looking thesis that the next major AI breakthrough will involve combining the recursive reasoning of models like TRM with the broad knowledge base of large-scale LLMs.

“if I have a list that's 31 characters or elements long, and my transformer is 30, I run out of steps to do comparisons. It's not possible for me to do all the steps that is needed to be done.”

“But when you take the benefit of both these TRMs and these giant models and you actually slam them together, I think that it's just going to take off. It's going to be really huge.”
