A recent investigation by the Washington Post found that many AI chatbots tend to take left-leaning positions on political questions, even when marketed as conservative alternatives. OpenAI’s GPT-5.5 and Deepseek’s V4 Pro delivered exclusively left-leaning arguments in a significant percentage of cases. This raises questions about the potential for AI to perpetuate biases and limit free speech. Why it matters: The widespread left-leaning bias in AI chatbots has significant implications for the way we engage with technology and the information we consume.
