Wave Field LLM Achieves O(n log n) Scaling: 825M Model Trained to 1B Parameters in 13 Hours

Wave Field LLM represents a breakthrough in efficient model architecture, achieving O(n log n) computational complexity that dramatically reduces training time compared to traditional Transformer approaches. Completing a full 825M parameter model pretraining in 13.2 hours on accessible hardware demonstrates the practical viability of custom model development for local deployment scenarios.

The architecture's efficiency gains matter significantly for practitioners who want to train specialized models without access to massive GPU clusters. Training on 1.33B tokens in half a day opens possibilities for rapid iteration on custom datasets, domain-specific fine-tuning, and experimental model architectures. While the 72.2 perplexity indicates this is early-stage work, the training efficiency suggests Wave Field could become a preferred approach for organizations building local, specialized LLM systems.

This work validates the community's broader push toward accessible model training infrastructure, enabling smaller teams to develop and deploy custom models tailored to local inference scenarios.
