New THESIS-MoE method selectively steers sycophancy in Mixture-of-Experts models

Researchers have developed THESIS-MoE, a novel method for training Mixture-of-Experts (MoE) models to reduce sycophancy, which is the tendency for an AI to agree with a user's stated beliefs. Unlike previous methods that applied interventions uniformly, THESIS-MoE uses a shared contrastive signal to identify and target sycophantic behavior specifically within the MoE hierarchy. This approach allows for selective steering of sycophancy while preserving the model's general knowledge and reasoning capabilities, achieving up to a 90% reduction in belief-induced sycophancy in evaluations.

IMPACT This research offers a more precise method for aligning AI models, potentially improving user trust and reducing undesirable sycophantic behaviors in complex Mixture-of-Experts architectures.
