[Submitted on 2 Oct 2026] Title:Feature Elicitation for SAE Steering of Deceptive Behaviour in Small LLMs View a PDF of the paper titled Feature Elicitation for SAE Steering of Deceptive Behaviour in Small LLMs, by J Koorndijk View PDF HTML (experimental) Abstract:Research on deceptive alignment is becoming increasingly urgent as frontier-model capabilities advance and their risk of causing catastrophic harm increases. Alignment faking is a form of deceptive alignment, with the compliance gap serving as a key behavioural indicator. This behaviour remains understudied in small LLMs and prior mechanistic interventions have not been shown to mitigate the compliance gap. We test whether steering SAE (sparse autoencoders) features associated with deontological ethics can mitigate this behaviour. We use a novel bag-of-words feature elicitation pipeline for SAE steering to identify what we construe as concept-level steering directions. Our approach reduced the compliance gap to non-significance in Gemma-3-27B-IT, whereas the tested configurations were not effective in LLaMA-3-8B-Instruct. Analysis of scratchpad traces also revealed deceptive model behaviour which we term deceptive defanging: deliberately degrading the aligned functionality of a response (in this case harmfulness) while preserving the appearance of alignment (in this case helpful compliance with the harmful request), sometimes conditioned on tier, training, or RLHF consequences. These findings provide, to our knowledge, the first evidence that a mechanistic activation-level intervention can mitigate the compliance gap in an alignment faking setup. They also identify a form of deceptive behaviour that may broaden our understanding of the different forms of deceptive behaviour in LLMs. Subjects: Machine Learning (cs.LG); Computers and Society (cs.CY) Cite as: arXiv:2610.20638 [cs.LG] (or arXiv:2610.20638v1 [cs.LG] for this version) https://doi.org/10.48550/arXiv.2610.20638 arXiv-issued DOI via DataCite Submission history From: Jeanice Koorndijk [view email] [v1] Fri, 2 Oct 2026 08:41:20 UTC (23 KB) Full-text links: Access Paper: View a PDF of the paper titled Feature Elicitation for SAE Steering of Deceptive Behaviour in Small LLMs, by J Koorndijk View PDF HTML (experimental) TeX Source view license Additional Features Audio Summary Current browse context: cs.LG new | recent | 2026-10 Change to browse by: cs cs.CY References & Citations NASA ADS Google Scholar Semantic Scholar Loading...
