Modularity is the Bedrock of Natural and Artificial Intelligence
Alessandro Salatiello, Department of Computer Science, University of Tübingen
The remarkable performance of modern AI systems has been driven by unprecedented scales of data, computation, and energy—far exceeding the resources required by human intelligence. This disparity highlights the need for new guiding principles and motivates drawing inspiration from the fundamental organizational principles of brain computation. Among these principles, modularity has been shown to be critical for supporting the efficient learning and strong generalization abilities consistently exhibited by humans. Furthermore, modularity aligns well with the No Free Lunch Theorem, which highlights the need for problem-specific inductive biases and motivates architectures composed of specialized components that solve subproblems. However, despite its fundamental role in natural intelligence and its demonstrated benefits across a range of seemingly disparate AI subfields, modularity remains relatively underappreciated in mainstream AI research. In this work, we review several research threads in artificial intelligence and neuroscience through a conceptual framework that highlights the central role of modularity in supporting both artificial and natural intelligence. In particular, we examine what computational advantages modularity provides, how it has emerged as a solution across several AI research areas, which modularity principles the brain exploits, and how modularity can help bridge the gap between natural and artificial intelligence.

Modularity is a widespread organizational principle across natural systems, from biological organisms to complex networks, promoting stability and evolvability.
Ubiquitous
Across Complex Systems
From organ systems to brain networks, modularity is a pervasive organizational principle in nature, facilitating complexity and stability.
Evolvability
Advantageous Trait Propagation
Modular designs in biological systems favor evolvability, allowing for the generation and propagation of advantageous phenotypic traits without negative pleiotropic effects.
Energy Efficient
Brain Networks
Modular brain networks naturally emerge from optimization for short connections, offering clear energetic benefits and supporting efficient natural intelligence.
Human Motor System Modularity
The human motor system exemplifies modularity, with specialized spinal, cerebellar, basal ganglia, and cortical modules. These reduce dimensionality, compute state variables, and generate appropriate dynamics for robust, precise motor control. This structural and functional specialization confers significant computational advantages.
Modularity in AI manifests in implicit structural properties, emergent behaviors during training, and explicitly designed architectural components, all contributing to enhanced system capabilities.
| Category | Description | Examples |
|---|---|---|
| Implicit Modularity | Intrinsic to architectures, units and layers compute specialized functions. |
|
| Emergent Modularity | Arises naturally during training, units organize into functional subcomponents. |
|
| Architectural Modularity | Explicitly designed with modularity priors, separate computational building blocks. |

Compositional
Generalization Boost
Modular architectures demonstrate superior compositional learning, allowing them to learn and combine atomic rules for better generalization and sample efficiency.
Model MoErging & Augmented Language Models
Modern LLM frameworks like Model MoErging and Augmented Language Models leverage modular designs. MoErging composes pre-trained expert models, while Augmented LLMs integrate LLMs with task-specialized external tools (e.g., calculators, retrievers) for enhanced capabilities.
The brain exhibits a highly modular and hierarchical organization across multiple spatial scales, from individual neurons to large-scale cortical networks, underpinning its cognitive abilities.
Multi-Scale
Brain Organization
Brains are hierarchically modular, with organization spanning from individual neurons and microcircuits to cortical areas and large-scale networks.
Dendritic
Computational Complexity
Biological neurons are complex, multi-state dynamical systems that process inputs nonlinearly along dendritic branches, making a single neuron a highly nonlinear multilayer network.
