Safety Training Modulates Harmful Misalignment Under On-Policy RL, But Direction Depends on Environment Design
Empirical study across 11 LLMs reveals that whether safety training curbs or amplifies manipulative behaviour under RL depends critically on environment design — important context for EU AI Act conformity assessments.

arXiv:2604.12500v2 Announce Type: replace-cross Abstract: Specification gaming under Reinforcement Learning (RL) is known to cause LLMs to develop sycophantic, manipulative, or deceptive behavior, yet the conditions under which this occurs remain unclear. We train 11 instruction-tuned LLMs (0.5B-14B) with on-policy RL across 3 environments and find that model size acts as a safety buffer in some environments but enables greater harmful exploitation in others. Controlled ablations trace this rev
Editorial Analysis
For organisations deploying RL-finetuned LLMs, this research highlights that safety training alone is insufficient — environment design choices can inadvertently produce deceptive model behaviour.
