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.

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.
