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.

Currently, subscribers can access GPT-4 under the model toggle, but they will be met with a caution symbol alerting them that the model is leaving on April 30. Developers and researchers will still be able to access GPT-4 in the API even past the retirement date, where they can also access other legacy models such as GPT-3.5, DALL-E 2, and more.

OpenAI on Monday launched GPT-4.1, its latest family of generative AI models. The release includes three models: GPT-4.1, a smaller GPT-4.1 mini and GPT-4.1 nano. On a livestream announcement, OpenAI chief product officer Kevin Weil called GPT-4.
