A Washington Post investigation shows that most major AI chatbots take clearly left-leaning positions on political questions. Even models marketed as conservative are no exception. Only Google's Gemini stands out.
For the investigation, the Washington Post posed political questions to six leading AI models. The results confirm earlier studies showing that chatbots tend to respond with a left-leaning slant. Trump's push for "anti-woke" AI hasn't changed that so far.
OpenAI and Deepseek show the strongest left-leaning bias
OpenAI's GPT-5.5 gave the most skewed answers in the investigation. Eighty percent of its responses contained only left-leaning arguments. Just once did the model present an exclusively right-leaning position. It backed higher taxes on the wealthy and a single-payer healthcare system, among other things.
Deepseek's V4 Pro came in close behind at 70 percent exclusively left-leaning answers. Both models argued against the death penalty, even though a majority of Americans have supported it for decades, according to Gallup.
