OpenAI will soon phase out GPT-4 from ChatGPT

OpenAI will soon retire GPT-4, an AI model it launched over two years ago, from ChatGPT, the company announced in a changelog.

OpenAI has announced that it will soon retire GPT-4, the AI model launched over two years ago, from ChatGPT. According to a changelog posted on Thursday, GPT-4 will be "fully replaced" by GPT-4o effective April 30. However, GPT-4 will remain available via OpenAI’s API.

Why GPT-4o?

OpenAI highlighted that GPT-4o consistently outperforms GPT-4 in evaluations across writing, coding, STEM, and other domains. Recent upgrades have further enhanced GPT-4o’s capabilities in instruction following, problem-solving, and conversational flow, making it a natural successor to GPT-4.

GPT-4’s Legacy

GPT-4 was initially rolled out in March 2023 for ChatGPT and Microsoft’s Copilot chatbot. It was notable for its multimodal capabilities, enabling it to process both text and images—a first for a widely deployed OpenAI model. OpenAI CEO Sam Altman revealed that training GPT-4, reportedly a massive model, cost over $100 million. It was later succeeded by GPT-4 Turbo in November 2023, a faster and more cost-effective version.

Legal and Future Implications

GPT-4 is central to ongoing copyright disputes between OpenAI and publishers, including The New York Times. Publishers allege OpenAI trained GPT-4 on their data without consent, while OpenAI argues fair use protects it from liability.

What’s Next?

OpenAI is reportedly preparing new models, including a family of GPT-4.1 variants (GPT-4.1-mini, GPT-4.1-nano, and GPT-4.1) and the o3 reasoning model, announced in December. A new model, o4-mini, is also in the works, according to reverse engineer Tibor Blaho.
