Researchers have developed a new framework called CircuitSteer, which uses Sparse Autoencoders to identify and manipulate specific semantic circuits within multiple layers of large language models. This method allows for more precise control over model behavior by synthesizing dense steering vectors from sparse features and applying multi-point interventions. CircuitSteer has demonstrated superior performance over existing methods like Contrastive Activation Addition, consistently producing fluency-preserving interventions and effectively guiding models on complex behaviors such as sycophancy and refusal across various tasks and model families.
