Learn why GPT-4.1 is a fantastic AI tool for developers, offering advanced capabilities, cost-effective performance, and versatile apps

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 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.
