New ORBIT method enables multi-attribute steering in language models

Researchers have developed ORBIT, a novel training-free method for simultaneously steering multiple behavioral attributes in language models. Unlike previous methods that struggle with combining attributes or require retraining, ORBIT uses singular value decomposition to create a joint subspace for steering planes, applying a single rotation to achieve combined target directions. This approach also includes adaptive per-token gating and an optional additive boost for weak attributes. ORBIT was evaluated on a new benchmark, TraitFactory, and ToneBank across several models, demonstrating superior multi-attribute steering and better output coherence compared to existing baselines.
