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.

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 has launched new GPT-4.1 models (including mini and nano variants) specifically for developers via API. These models are now available through Microsoft as well.
