OpenAI is retiring GPT-4 from ChatGPT

April 14, 2025

🤖 OpenAI is retiring GPT-4 from ChatGPT: Slated to be fully replaced by April 30 by the current default model, GPT-4o, because, well, 4o is just better. It’s stronger at writing, coding, problem-solving and conversational flow. Farewell, GPT-4. We’ll remember your weird poem phase. More models are on the way; we’ll soon see a family of GPT-4.1s and a new o3 “reasoning” bot.
