New research reveals functional decoupling in Transformer language models' causal knowledge organization

Researchers have identified a functional decoupling in how Transformer language models organize causal knowledge. They found that while a model's ability to answer interventional questions depends on the type of evidence required, the internal structure for organizing this knowledge (slot-by-type) is primarily used for routing information and is largely separate from the process of generating the final answer. This finding was established using a "typed mechanism library" on a causal-world benchmark at different scales, demonstrating that this structural organization is induced by specific supervision signals and is computationally efficient.
