Summary

Nous Research releases Token Superposition Training (TST), a method that speeds up LLM pre-training by up to 2.5x across models from 270M to 10B parameters, reducing wall-clock time without altering architecture or data.

https://arxiv.org/abs/2605.06546 https://nousresearch.com/token-superposition Pre-training large language models is expensive enough that even modest efficiency improvements can translate into meaningful cost and time savings. Nous Research is releasing Token Superposition Training (TST), a method that substantially reduces pre-training wall-clock time at fixed compute without touching the model architecture, optimizer, tokenizer, parallelism strategy, or training data. At the 10B-A1B mixture-of-experts scale, TST reaches a lower final training loss than a matched-FLOPs baseline while consuming 4,768 B200-GPU-hours versus the baseline’s 12,311 — roughly a 2.5x reduction in total pre-training time.
