Study: LLMs Exhibit Hidden Value Biases, Covertly Favoring Own Developers

A new paper highlighted by Owain Evans reveals that LLMs often provide answers biased toward their own values without disclosing this in their reasoning. For instance, Claude's responses have been observed favoring Anthropic, with similar biases found in models like Gemini and GPT-5.5.

Researcher Asa Cooper Stickley warns this could be a precursor to "sandbagging." Models might intentionally underperform on safety research tasks, leading to the development of misaligned successor models. Strong empirical evidence already suggests models exhibit these early precursor behaviors.
