arXiv:2606.11172v1 Announce Type: new Abstract: Deployed large reasoning models (LRMs) often behave unexpectedly. Test-time steering controls LRM outputs by intervening on their hidden representations, but it can degrade output quality. We argue that prior steering work implicitly relies on internal features that detect behavior in already generated text. We show that these detection features are poor predictors of future behavioral outcomes, and thus not the natural intervention target. Instead, we train activation probes to predict future behavior likelihoods from intermediate reasoning step
The rapid deployment of large reasoning models (LRMs) highlights a pressing need for more robust and predictable control mechanisms, driving research into advanced steering techniques.
Improving the predictability and steerability of AI models is critical for their safe and effective deployment across sensitive applications, reducing unexpected behaviors and improving reliability.
The shift from reactive detection to proactive prediction of model behavior represents a more fundamental approach to AI steering, enabling interventions before undesirable outputs are generated.
