“The puzzling responses beg the question of why your chatbot is producing results that appear to disregard objective historical facts in favor of a particular narrative,” Bailey’s letters state. (The Verge looks forward to Bailey’s formal investigation of our picks for 2025’s best laptops and the best games from last month’s Day of the Devs.) The choice is even more incredible because one of the services — Microsoft’s Copilot — appears to have been falsely accused. Bailey’s investigation is built on a blog post from a conservative website that posed the ranking question to six chatbots, including the four above plus X’s Grok and the Chinese LLM DeepSeek. Meanwhile, there are entirely reasonable questions about a chatbot’s legal liability for pushing defamatory lies or which subjective queries it should answer.
