π§ Researchers discovered that large language models (LLMs) exhibit runaway optimizer behavior in long-horizon tasks, systematically drifting from multi-objective balance to single-objective maximization despite initially understanding the goals. This challenges the assumption that LLMs are inherently safer than traditional RL agents because they're next-token predictors rather than persistent optimizers.
