PANews reported on February 28 that according to OpenAI's announcement, GPT-4.5 was officially released. The first batch has been opened to ChatGPT Pro users, and will cover Plus and Team users next week, and then Enterprise and Edu users. The model has improved its knowledge breadth, comprehension ability, and user interaction experience compared to the previous generation, and has reduced the "hallucination" phenomenon.

GPT-4.5 uses larger-scale unsupervised learning to enhance pattern recognition, logical connection, and creative generation capabilities, but does not have reasoning capabilities. Its improvements include stronger emotional intelligence (EQ), a more natural conversation experience, and enhancements in writing, programming, and automation of complex tasks. In addition, the model supports file and image input, but does not currently support voice mode, video, and screen sharing. OpenAI said that it will optimize the user experience in the future to make AI more intuitive and easy to use.
