A new study published on arXiv reveals that geopolitical biases in large language models (LLMs) are primarily introduced during the post-training alignment phase, rather than originating from the initial training data. Researchers observed significant shifts in geopolitical favorability after post-training across seven different AI labs, with Alibaba's Qwen 2.5 showing an 18-fold increase in pro-China bias. The study also found that the language used in prompts can amplify these biases, as demonstrated by the French-made Mistral model becoming pro-France only when prompted in French. These findings underscore the critical need for transparency and oversight in the alignment processes that shape LLM representations of nations and cultures. AI
