ChatGPT, for smarter service delivery, transitions to GPT-4o

OpenAI will phase out its GPT-4 model from ChatGPT by April 30, 2025, replacing it with GPT-4o—a sharper, more capable model with superior performance in coding and solving science and mathematical problems.

The Microsoft-backed AI startup said in a statement on Thursday that the shift follows upgrades that have strengthened GPT-4o’s instruction-following and conversational abilities, areas where it now consistently outperforms its predecessor in testing.

The transition gives ChatGPT’s 400 million weekly active users access to a more intuitive tool, designed to generate cleaner front-end code and handle complex technical tasks with greater reliability.

Part of the announcement read, “Recent upgrades have further improved GPT‑4o’s instruction following, problem solving, and conversational flow, making it a natural successor to GPT-4,” it said.

“GPT-4o has further improved its capability to tackle complex technical and coding problems. It now generates cleaner, simpler frontend code, more accurately thinks through existing code to identify necessary changes, and consistently produces coding outputs that successfully compile and run, streamlining your coding workflows,” the startup added.

According to OpenAI, users testing the updated model have also reported improved performance in creative tasks and a clearer, more concise communication style.

The upgraded GPT-4o is already available in ChatGPT and through the API as the latest version under “chatgpt-4o-latest.”

OpenAI said it plans to bring these enhancements to an older model in the API in the coming weeks.
