in English In recent years, with the development of AI (artificial intelligence) technology, the popularity of chat GPT (chat production pre-training) has increased rapidly. The Chat GPT free version is especially widely used among them and has brought new lessons to many users. In this article, we will explore in detail the lessons learned from the Chat GPT free version. 1. The evolution of technology is fast. One of the lessons learned from the Chat GPT free version is that the evolution of technology is very fast. Artificial intelligence technology is advancing day by day and new functions and algorithms are being developed one after another. Therefore, users need to constantly monitor the latest information and respond to the evolution of technology. Through the chat GPT free version, we were absolutely aware of the speed of the evolution of the technology and learned that it is important to keep learning all the time. 2. The importance of user experience Using the Chat GPT free version, we have reaffirmed the importance of the user experience. Providing user-friendly interfaces and natural conversations is crucial to the success of artificial intelligence technology. The Chat GPT free version was improved by receiving user feedback, and the user experience was improved in the process. We have always put the user experience first and learned the importance of improving the service accordingly. 3. Response to diversity The Chat GPT free version must correspond to a variety of languages and cultures. Users can come from anywhere in the world and ask for communication to suit their culture and language. When developing the free version of Chat GPT, you need to respect the variety and the flexibility to respond to it. We learned the importance of respecting diversity and adopting a comprehensive approach. 4. The importance of data The importance of data in the development of the free version of Chat GPT has been reaffirmed. AI technology requires a large amount of data, and it extracts molds from that data and learns them. Therefore, high-quality data is essential. The development team of the Chat GPT free version collects many data sets and uses them to train models. We learned the importance of ensuring the quality and quantity of data. 5. Error cycle and improvement Finally, one of the lessons learned from the chat GPT free version is the importance of the error and improvement cycle. AI technology is not perfect and sometimes produces the wrong response. However, you can improve the quality of the service by collecting, analyzing and improving errors. The development team of the free version of Chat GPT collects feedback from users
