Internet reports that OpenAI said on its website that starting from April 30, GPT-4 will be "completely replaced" by GPT-4o, but GPT-4 will continue to be available through the API. OpenAI said,"In face-to-face evaluations, it (4o) continues to exceed GPT-4 in writing, coding, STEM, etc." According to US media The Verge reported on the 10th, OpenAI will announce a series of new AI models next week, including GPT-4.1, which will be an improved version of the 4o multimodal model. OpenAI will also launch smaller versions of GPT-4.1 mini and nano, as well as the o3 "inference" model and a new inference model called o4-mini.
