New method reveals shared algorithmic cores in large language models

Researchers have developed a new method called Algorithmic Core Extraction (ACE) to identify the essential computational structures within transformer models. This technique isolates compact subspaces that are crucial for a task and consistently appear across different training runs and model architectures. By analyzing these invariant cores, the study reveals that large language models like GPT-2, LLaMA-3.1, Gemma-2, and Qwen2.5 share a common underlying structure for grammatical number processing, which can be manipulated to alter text generation.
