LLMs' context vs. memory choice analyzed in new research

Researchers have investigated how large language models like Qwen, Llama, and OLMo decide whether to rely on provided context or their internal parametric knowledge when faced with conflicting information. Through counterfactual experiments, they found that interventions based on learned "authority directions" could reproduce a significant portion of the shift in source choice, suggesting these directions play a role in how models prioritize information. However, the study also indicated that these authority computations might be task-dependent rather than universally reusable across different tasks. AI

IMPACT This research sheds light on the internal decision-making processes of LLMs, potentially informing future model development for more reliable information retrieval.

    How Do Language Models Choose Between Context and Memory?

    arXiv:2609.00753v1 Announce Type: cross Abstract: When contextual information conflicts with the knowledge stored in model parameters, activation directions can be used to decode and steer which source the model follows. However, steering along a direction does not establish caus…
