Language models exhibit 'self-commitment' in answering questions

By PulseAugur Editorial · [1 sources] ·

Researchers have investigated how language models commit to answers, finding that a model's initial response to a yes/no question influences its subsequent answers on related topics. This phenomenon, termed 'self-commitment,' is achieved by writing a 'commitment direction' into the model's residual stream. The study analyzed 22 open-weight models and found that the similarity of these commitment directions predicts how coupled answers are, with ablating a shared direction significantly reducing this effect. The way this direction is interpreted varies with model scale, instruction tuning, and system prompts, suggesting a complex interplay in how models maintain consistency. AI

IMPACT Reveals a new mechanism for understanding how LLMs maintain consistency and potentially exhibit emergent reasoning capabilities.

    Written Once, Read Differently How Language Models Own Answers Steer Their Next Ones

    arXiv:2611.03198v1 Announce Type: new Abstract: When a language model answers a yes/no question, that answer changes how it answers a different question about the same entity. We study this \emph{self-commitment} in 22 open-weight models from four families (0.5B--72B parameters),…
