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 has introduced GPT-4.1, a successor to the GPT-4o multimodal AI model launched by the company last year. During a livestream on Monday, OpenAI said GPT-4.1 has an even larger context window and is better than GPT-4o in “just about every dimension,” with big improvements to coding and instruction following.

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.
