人工智能聊天机器人ChatGPT是使用深度学习技术、能对自然语言输入产生类似人类反应的一种大型语言模型(LLMs)。它由OpenAI公司在2022.11开发，属于“生成预训练转换器(GPT)”模型家族的一种，目前可为公众所用。ChatGPT能够捕捉人类语言的细微差别和复杂性，生成适当的、与上下文相关的响应。它可以帮助医务人员完成各种任务，如研究、诊断、患者监护和医学教育，从确定研究课题到协助临床和实验室诊断，了解各自领域的新进展和科学写作。ChatGPT在眼科已吸引了越来越多的关注和广泛应用。然而，目前在这些任务中使用ChatGPT和其他人工智能工具仍存在一定的局限性、伦理和法律问题，如可信度、剽窃、版权侵犯和偏见。未来的研究将集中在开发新的方法来减轻这些局限性，同时发挥ChatGPT在医疗等相关方面的积极作用。

ChatGPT is a large language models(LLMs)that uses deep learning techniques to produce human-like responses to natural language inputs. It belongs to the family of generative pre-training transformer(GPT)models currently publicly available developed by OpenAI in November 2022. ChatGPT is capable of capturing the nuances and intricacies of human language, generating appropriate and contextually relevant responses. It can assist medical professionals in various tasks, such as research, diagnosis, patient monitoring, and medical education, from identifying research programs to assisting in clinical and laboratory diagnosis, to know new developments in their fields and scientific writing. ChatGPT has also attracted increasing attention and widely used in ophthalmology. However, the use of ChatGPT and other artificial intelligence tools in such tasks comes now with several limitations, ethical and legal concerns, such as credibility, plagiarism, copyright infringement, and biases. Future research can focus on developing new methods to mitigate these limitations while harnessing the benefits of ChatGPT in medicine and related aspects.
