OpenAI has released GPT-4.1, a new family of generative multimodal AI models that outperform GPT-4o, the company said in a livestream on Monday.The release includes three models: GPT-4.1, a smaller GPT-4.

OpenAI claims the full GPT-4.1 model outperforms its GPT-4o and GPT-4o mini models on coding benchmarks, including SWE-bench. GPT-4.1 mini and nano are said to be more efficient and faster at the cost of some accuracy, with OpenAI saying GPT-4.1 nano is its speediest — and cheapest — model ever.

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.
