OpenAI will soon retire GPT-4, an AI model it launched over two years ago, from ChatGPT, according to a changelog posted on Thursday. Effective April 30, GPT-4 will be “fully replaced” by GPT-4o, the current default model in ChatGPT, OpenAI said. GPT-4 will remain available for use via OpenAI’s API. “In head‑to‑head evaluations, [GPT-4o] consistently surpasses GPT‑4 in writing, coding, STEM, and more,” wrote OpenAI in the changelog. “Recent upgrades have further improved GPT‑4o’s instruction following, problem solving, and conversational flow, making it a natural successor to GPT‑4.” GPT-4 was rolled out in March 2023 for ChatGPT and Microsoft’s Copilot chatbot on the web. Several versions of GPT-4 had multimodal capabilities, allowing them to understand both images and text — the first for a widely deployed OpenAI model. OpenAI CEO Sam Altman has said that GPT-4, reportedly massive in size, cost more than $100 million to train. It was succeeded by GPT-4 Turbo in November 2023, a faster and cheaper model.
