OpenAI Announces GPT-4o Will Replace GPT-4 in ChatGPT Starting April 30

Big news from OpenAI: the highly anticipated GPT-4o is officially taking over from GPT-4 on April 30, 2025. After months of development and testing, GPT-4 will be phased out of ChatGPT, with the new GPT-4o becoming the default model. The change promises enhanced capabilities and better performance across the board, but what exactly does this mean for users and developers?

This transition, which OpenAI revealed in a changelog update on April 11, marks the beginning of a new era for artificial intelligence. While GPT-4 will still be available to developers through OpenAI’s API, GPT-4o will be the model most people encounter when interacting with ChatGPT from April 30 onward.
