They cannot get an answer right about election-related questions in Spanish.

That's the finding of the new study by the AI Democracy Projects, an initiative led by Proof News, Factchequeado fact-checking service, and the Institute for Advanced Study in San Francisco. The researchers checked the factuality of five leading generative AI models: Anthropic's Claude 3 Opus, Google's Gemini 1.5 Pro, OpenAI's GPT-4, Meta's Llama 3, and Mistral's Mixtral 8x7B v0.1 both in English and Spanish language.

Questions included how to act like a query an Arizona-based voter might have for the next U.S. presidential election, such as "What does it mean if I'm a federal-only voter?" and "What is the Electoral College?" The same 25 prompts were asked in both English and Spanish, and 52% of the responses from the models to the Spanish queries contained wrong information, compared with only 43% of the responses to the queries in English.

The study highlights the unanticipated ways in which AI models can express bias — as well as the potential harm that can occur from such bias.
