arXiv:2606.07404v1 Announce Type: new Abstract: This paper reports on training a hundred-billion-parameter sparse mixture of experts on a single eight-GPU node, end to end. LightningLM 0.1V is a recurrence-backbone language model family grown in four stages from a small dense seed, through a 5B and a 9B mixture of experts, to a 120B model with 460 routed experts under top-12 routing. Each larger model is grown from the trained weights of the smaller one; active parameters rise monotonically from 1.78B at the dense seed to 5.93B at 120B (about 5% of the 118.67B stored). The full lineage runs on
The paper demonstrates a significant advancement in training large sparse models efficiently, pushing the boundaries of what is possible with accessible hardware.
This development indicates that highly capable large language models could become more widely available and trainable by smaller entities, reducing dependency on hyperscalers.
The ability to train a 120B model on a single 8-GPU node democratizes access to large model development and deployment capabilities.
