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.

OpenAI launched a new family of AI models this morning that significantly improve coding abilities while cutting costs, responding directly to growing competition in the enterprise AI market. The San Francisco-based AI company introduced three models — 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.
