A new analysis by the Washington Post has found that several leading artificial intelligence chatbots lean left on political questions, with OpenAI's ChatGPT producing the most one-sided responses of any major AI model tested. Claude from Anthropic was also likely to give more left-wing answers in addition to DeepSeek and Ayra’s Gab. Google’s Gemini and xAI’s Grok were the most balanced out of the models.
According to the report, ChatGPT's GPT-5.5 model answered approximately 80 percent of political questions using exclusively left-leaning arguments while presenting only right-leaning positions just once throughout the testing process. The most left-wing chatbot, aside from ChatGPT, was the AI from Chinese company DeepSeek.

I tested six AI models on 30 political questions. Most tended to give left-leaning arguments. Gemini mostly gave both sides — even about whether the U.S. should conquer new territories.
