It’s official: GPT-4 is being retired from ChatGPT. OpenAI recently announced that starting April 30, 2025, GPT-4 will no longer be available to ChatGPT users, with GPT-4o stepping in as the new default model.

OpenAI has announced that GPT-4, the AI model launched two years ago, will be retired from ChatGPT on April 30, 2025. According to a changelog posted by the company, GPT-4 will be fully replaced by GPT-4o, OpenAI’s new multimodal model. The company noted that GPT-4 will still remain available in the API.

OpenAI has introduced GPT-4.1, a successor to the GPT-4o multimodal AI model launched by the company last year. During a livestream on Monday, OpenAI said GPT-4.1 has an even larger context window and is better than GPT-4o in “just about every dimension,” with big improvements to coding and instruction following.
