New V-Steer method enforces instruction hierarchy in LLMs at inference time

Researchers have developed V-Steer, a novel method to ensure that higher-priority instructions in language models are respected during inference. This training-free technique modifies cached value vectors to boost privileged instructions and suppress conflicting lower-priority ones. V-Steer significantly improves accuracy on role conflict benchmarks, raising performance from under 18% to 92% across various model sizes, and offers a competitive alternative to training-based methods with minimal overhead.

    Steering Instruction Hierarchies at Inference Time

    arXiv:2607.26228v1 Announce Type: new Abstract: Instruction hierarchies are a core safety assumption of language model deployment: higher priority inputs, such as system prompts, should override conflicting lower priority inputs from users or tools. Yet frontier LLMs often violat…
