arXiv:2606.17945v1 Announce Type: new Abstract: Large language models provide a tractable system for asking how intelligence itself emerges, rather than only how LLMs can be engineered. Although progress is usually attributed to scale, data and architecture, we show that parameter initialization is a gene-like determinant of training and, in particular, of model capacity. Reducing the initialization scale consistently improves pretraining, with the largest gains on reasoning-demanding tasks. We identify two widely used empirical settings that restrain the advantage of small initialization, and
The continuous push for larger and more capable LLMs necessitates a deeper understanding of fundamental training mechanics to optimize performance and resource utilization.
This research reveals a critical, often overlooked, determinant in large language model training that can significantly impact model capacity and reasoning abilities, challenging the sole emphasis on scale, data, and architecture.
The optimal approach to LLM initialization is being redefined, potentially leading to more efficient training processes and models with enhanced reasoning capabilities, particularly for demanding tasks.

Further research and adoption of optimized initialization techniques for LLMs will accelerate model development.
More sophisticated and efficient LLMs could emerge without solely relying on exponential increases in computational resources.
The democratization of advanced AI development might increase if efficiency gains reduce the barrier to entry for training powerful models.
