Japan tops culture answers in 5 of 8 AI models, study finds

3 Key Points

  1. What happened

    A University of the Basque Country and Cardiff University team tested 8 models in 24 languages across 11 fields; five models named Japan most often, two named the US, and one tied.

  2. Why it matters

    The result suggests the countries an AI surfaces when asked about culture are shaped by which model is used, not simply by which culture is most prominent, the researchers indicate.

WHO IT HITSBusinesses and researchers using LLMs to answer culture-related questions may need to check which countries the models default to, since the choice varies by model.

FAQ
Which AI models were tested?
GPT-4o mini, Gemini 2.5 Flash, Claude 3.5 Haiku, Llama 4 Maverick, Command R, Magistral Small, DeepSeek V3.2 Exp, and Qwen3 Next.
Did the language of the question affect the answers?
Yes. Mentions of countries where the question language is official ranged from 43% to 78% of responses, depending on the model.
Do the researchers know why Japan is chosen so often?
No. They found that countries appearing often in OLMo's fine-tuning data were not necessarily chosen more in answers; China, for example, appeared most in one model's data but rarely in answers.
