Training Language Models via Neural Cellular Automata
Pre-training is crucial for large language models (LLMs), as it is when most representations and capabilities are acquired. However, natural language pre-training has problems: high-quality text is finite, it contains human biases, and it entangles knowledge with reasoning. This raises a fundamental question: is natural language the only path to intelligence? We propose using neural cellular automata (NCA) to generate synthetic, non-linguistic data for pre-pre-training LLMs-training on synthetic-then-natural language. NCA data exhibits rich spatiotemporal structure and statistics resembling natural language while being controllable and cheap to generate at scale. We find that pre-pre-training on only 164M NCA tokens improves downstream language modeling by up to 6% and accelerates convergence by up to 1.6x. Surprisingly, this even outperforms pre-pre-training on 1.6B tokens of natural language from Common Crawl with more compute. These gains also transfer to reasoning benchmarks, including GSM8K, HumanEval, and BigBench-Lite. Investigating what drives transfer, we find that attention layers are the most transferable, and that optimal NCA complexity varies by domain: code benefits from simpler dynamics, while math and web text favor more complex ones. These results enable systematic tuning of the synthetic distribution to target domains. More broadly, our work opens a path toward more efficient models with fully synthetic pre-training.

Leveraging Neural Cellular Automata for LLM Pre-training
The core innovation lies in using Neural Cellular Automata (NCA) to generate synthetic, non-linguistic data for "pre-pre-training" large language models. This synthetic data mimics natural language's complex spatiotemporal structures and statistical properties, but is controllable and scalable.
This approach addresses key limitations of natural language pre-training: finite high-quality text, inherent human biases, and the entanglement of knowledge with reasoning. NCA provides a "purer" signal for in-context rule inference, fostering more robust and transferable computational primitives.

Understanding the Drivers of Transferability
The research delves into the internal mechanics of LLMs to explain why NCA pre-pre-training is effective, providing insights into which components are most crucial for learning transferable computational priors.
Attention Layers
The Most Transferable Components
Attention layers capture general-purpose mechanisms for tracking dependencies and inferring latent rules, which are universally beneficial. In contrast, MLP layers tend to encode more domain-specific knowledge, making their transfer more conditional.
Transferability to Reasoning Benchmarks
The gains from NCA pre-pre-training extend beyond perplexity, significantly improving performance on diverse reasoning benchmarks:
- GSM8K: Enhanced mathematical reasoning accuracy.
- HumanEval: Improved code generation capabilities.
- BigBench-Lite: Better performance on a wide array of reasoning tasks, especially at higher pass@k.
This suggests NCA instills fundamental reasoning skills, making LLMs more capable in complex problem-solving scenarios crucial for enterprise AI.
Tailoring Synthetic Data for Target Domains
A key finding is that the optimal NCA complexity for pre-pre-training is not one-size-fits-all, but is domain-dependent. This opens up a powerful new lever for enterprise AI development: systematically tuning the synthetic data distribution to match specific target domains.

This ability to "tune the training distribution" offers an unprecedented advantage over static natural language datasets, enabling the creation of more efficient and domain-aligned foundation models. It points towards a future where synthetic data is not just a supplement, but a strategically crafted core component of AI development.
