These cutting-edge models cater to various MBTI personality types, offering extensive language capabilities in both Chinese and English. They are designed to provide users with a unique and insightful experience while interacting with AI. ## Limited Access（INTJ Model） Due to the high computational costs involved in running these models, we regret that we can only open access to two publicly available spaces for testing. These spaces are dedicated to the INTJ model, both in Chinese and English. This limitation ensures that we can provide a high-quality and responsive experience to our users. For a more comprehensive understanding of the Machine Mindset project and to explore detailed information about the INTJ model and its unique features, we invite you to visit our official GitHub website at [https://github.com/PKU-YuanGroup/Machine-Mindset](https://github.com/PKU-YuanGroup/Machine-Mindset).
