GPT-4.1 mini, and GPT-4.1 nano models, available only via the API, will provide better performance than GPT-4o and GPT-4o mini at a lower price, OpenAI said.

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 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.
