New Token Superposition method slashes LLM pre-training time by 2.5x

By PulseAugur Editorial · Summary by gemini-2.5-flash-lite from 2 sources

Researchers have developed a new pre-training method called Token-Superposition Training (TST) that aims to make large language model training more efficient. TST involves a two-phase process: an initial superposition phase where tokens are combined and trained with a multi-hot cross-entropy objective, followed by a recovery phase of standard training. Evaluations on models up to 10 billion parameters show TST can reduce pre-training time by up to 2.5x under equal-loss conditions. AI
