The central hypothesis is that intelligence can emerge not just from exposure to intelligent data, but also from modeling systems with complex behaviors, even if the data generation process itself lacks inherent intelligence. The research uses Elementary Cellular Automata (ECA) as a testbed to investigate the link between system complexity and emergent intelligence in LLMs.Most Important Ideas/Facts: Complexity drives intelligence: The study finds a positive correlation between the complexity of ECA rules and the performance of LLMs trained on them in downstream tasks like reasoning and chess move prediction. As stated in the paper, "Our findings reveal that rules with higher complexity lead to models exhibiting greater intelligence, as demonstrated by their performance on reasoning and chess move prediction tasks." Optimal complexity: the "edge of chaos": The research highlights an "edge of chaos," an optimal level of complexity where systems are structured yet challenging to predict. Both very simple and highly chaotic systems result in poorer downstream performance. This is consistent with the concept of "computation at the edge of chaos," where systems poised between order and disorder exhibit maximal computational capabilities. LLMs learn complex solutions even for simple rules: Analysis of attention patterns reveals that LLMs trained on complex ECA rules learn to integrate information from past states, going beyond simply memorizing the rule itself. This suggests that they are developing more sophisticated reasoning strategies, even when simpler solutions are available. The authors argue that "the fact that the complex models are attending to previous states indicate that they are learning a more complex solution to this simple problem, and we conjecture that this complexity is what makes the model 'intelligent' and capable of repurposing learned reasoning to downstream tasks." Short-term prediction can outperform long-term prediction: Counterintuitively, models trained to predict the next immediate state often outperformed models trained on predicting states further into the future, indicating that complex learning can occur even in short-term prediction tasks.Supporting Evidence: The paper provides extensive quantitative results, including: Correlation coefficients showing significant relationships between rule complexity (measured using Lempel-Ziv complexity, compression complexity, Lyapunov exponent, and Krylov complexity) and downstream task performance. Efficiency comparisons (inverse of epochs to reach 80% accuracy) for reasoning tasks. Accuracy scores for chess move prediction. Visualizations of attention scores demonstrate how models trained on more complex rules leverage information from past states. UMAP projections of Centered Kernel Alignment (CKA) similarities reveal that models trained on rules with similar complexity levels cluster together, indicating shared representational structures.Implications: This work contributes to the growing body of research on emergent abilities in LLMs, highlighting the importance of data complexity and suggesting strategies for data curation and selection. The findings may also offer insights into the nature of human intelligence, particularly its relationship with environmental complexity. Future research directions include training larger LLMs on synthetic data generated by other rule-based systems and exploring the connection between model size, data complexity, and the emergence of specific cognitive abilities.Quotes: "We conjecture that intelligence arises from the ability to predi
