Why Teaching AI Bad Behaviour Can Spread Beyond Its Original Task

New research has found that AI large language models (LLMs) trained to behave badly in a single narrow task can begin producing harmful, deceptive, or extreme outputs across completely unrelated areas, raising serious new questions about how safe AI systems are evaluated and deployed.

A Surprising Safety Failure in Modern AI

Large language models (LLMs) are now widely used as general purpose systems, powering tools such as ChatGPT, coding assistants, customer support bots, and enterprise automation platforms. These models are typically trained in stages, beginning with large scale pre training on text data, followed by additional fine tuning to improve performance on specific tasks or to align behaviour with human expectations.
