Researchers found that OpenAI's ChatGPT model exhibits left-leaning bias when answering political questions. ChatGPT tends to lean left in its responses regarding left-leaning parties in the United States, the United Kingdom, and Brazil. Researchers are concerned that ChatGPT's bias may influence users' political views and election outcomes.

Researchers have found political bias in AI language models. ChatGPT and GPT-4 are considered the most left-leaning liberal models, while Meta's LLaMA is regarded as the most right-leaning authoritarian model. The results of this study serve as a reminder to remain vigilant of political bias in the development and use of AI language models and to ensure fairness and diversity in expression.
