According to BlockBeats, OpenAI announced on its website that starting April 30, GPT-4 will be completely replaced by GPT-4o, although GPT-4 will still be available through API access. OpenAI stated that in face-to-face evaluations, GPT-4o consistently outperforms GPT-4 in areas such as writing, coding, and STEM.
The Verge reported on the 10th that OpenAI is set to unveil a series of new AI models next week, including GPT-4.1, an improved version of the 4o multimodal model. Additionally, OpenAI plans to introduce smaller versions, GPT-4.1 mini and nano, as well as the o3 'reasoning' model and a new reasoning model named o4-mini.
