OpenAI is retiring GPT-4 from ChatGPT

According to ChatGPT's release notes (via TechCrunch), "GPT-4 will be retired from ChatGPT" on April 30. The model, which was released over two years ago, will still be available in the API, but recent updates to GPT-4o have rendered GPT-4 somewhat obsolete. "Recent upgrades have further improved GPT‑4o's instruction following, problem-solving, and conversational flow, making it a natural successor to GPT‑4," the note read. For those who have been following OpenAI and the AI industry, it puts the breakneck speed of the industry into sharp relief, while simultaneously pointing out that GPT-5 has yet to emerge. GPT-4, released in March 2023, was a notable step up from GPT-3.5, the previous model, which ushered in the ChatGPT explosive introduction to the world.
