An unbiased, purely fact-based AI chatbot is a cute idea, but it's technically impossible. To understand why, it's worth reading a story I just published on new research that sheds light on how political bias creeps into AI language systems. Researchers conducted tests on 14 large language models and found that OpenAI's ChatGPT and GPT-4 were the most left-wing libertarian, while Meta's LLaMA was the most right-wing authoritarian. "We believe no language model can be entirely free from political biases," Chan Park, a PhD researcher at Carnegie Mellon University, who was part of the study, told me. One of the most pervasive myths around AI is that the technology is neutral and unbiased.
