OpenAI prepares to send GPT-4 out to pasture

GPT-4, OpenAI's first big upgrade to ChatGPT months after unleashing it on the world, is on its way out. A changelog the company published on Thursday said the model will be retired from ChatGPT on April 30. GPT-4o, which has been available since last May, will fully replace it. OpenAI says GPT-4o improves on it in writing, coding and STEM. Recent upgrades have boosted the newer model further, enhancing its instruction following, problem-solving and conversational flow.
