The Wei Zexi incident of the past year made everyone aware of the relationship between search engines and the Putian system. It also revealed how inaccurate the medical advice obtained from searches can be. So, in the era of AI, is there no good way for AI to provide medical advice?
Actually, this future is not far off. There is an open-source project called DoctorGPT, which aims to provide each person with their own personal AI doctor.
DoctorGPT is based on a large language model that can pass the United States Medical Licensing Examination, meaning it possesses medical knowledge and abilities equivalent to a qualified doctor.
DoctorGPT is an improvement on the Llama2 model developed by Meta. Llama2 is a large language model with 7 billion parameters, larger than GPT-3, and uses more advanced algorithms and technologies.
Llama2 can run on any local device as it is only 3GB in size, while GPT-3 requires cloud servers to run. This means using DoctorGPT does not require payment for any APIs and does not need an internet connection, ensuring user privacy and security.
How does DoctorGPT become an AI doctor? Firstly, it is fine-tuned based on Llama2, meaning it undergoes additional training on a specific medical dialogue dataset to improve its ability to communicate on medical topics. Secondly, it uses reinforcement learning and constitutional AI to further enhance its performance and reliability.
Reinforcement learning is a method that allows the model to adjust its behavior based on feedback, while constitutional AI is a method that ensures the model follows certain principles and values. Both methods help DoctorGPT adhere to medical ethics and standards.
So, how impressive is DoctorGPT? According to the project, DoctorGPT has passed the first and second steps of the United States Medical Licensing Examination (USMLE).
These two steps are primarily multiple-choice exams that assess medical knowledge and clinical skills. This indicates that DoctorGPT has reached the level of a qualified doctor.
Of course, there is still much room for improvement and refinement for DoctorGPT. For example, it has not yet passed the third step of the USMLE, which is a case-based exam that primarily assesses a doctor's decision-making and management skills.
Furthermore, DoctorGPT has not undergone actual clinical practice and validation, so its diagnoses and recommendations may not be accurate or effective. Therefore, the project explicitly states not to consider any advice from DoctorGPT as genuine medical advice, as it could lead to serious harm or even death.
In conclusion, DoctorGPT is a very promising and potential AI doctor project that can provide people with a convenient, fast, private, and free medical consultation platform. If you are interested in DoctorGPT, you can visit its website or check out its source code and documentation on GitHub.
