New CHaRS method steers language models to reduce toxicity

Researchers have developed a new method for steering language model activations, called Clustered Optimal-Transport Steering (CHaRS). This technique uses optimal transport to pair clusters of classes and moves hidden states based on their proximity to these clusters, offering an alternative to the common practice of adding a single vector. Experiments on Gemma-2-2B and Granite-3-1-2B models showed that CHaRS, particularly a variant that routes tokens to their nearest clusters, significantly reduced toxicity compared to the standard method, even under INT8 and NF4 quantization.

    One Vector or Many? Clustered Optimal-Transport Steering under Quantization

    arXiv:2610.40055v1 Announce Type: cross Abstract: Activation steering changes what a language model generates by editing its hidden states at inference time. Its most common form adds one vector, the difference of class means (DiM), to every hidden state. CHaRS (concept heterogen…
