GPT-4.1 is a large language model within OpenAI's GPT series. It was released on April 14, 2025. GPT-4.1 can be accessed through the OpenAI API or the OpenAI Developer Playground.[1][2][3] Three different models were simultaneously released: GPT-4.1, GPT-4.1 mini, and GPT-4.1 nano.[4] Since May 14, GPT-4.1 has been available for users subscribed to the ChatGPT Plus and Pro plans, and GPT-4.1 mini that replaces GPT-4o mini is available for all ChatGPT users.[5]

Reception

Zvi Mowshowitz praised the model itself while criticizing OpenAI for not doing enough safety testing.[6]

Two research teams, one led by researcher Owain Evans, the other with the startup company SplxAI, independently found evidence that GPT-4.1 could be more misaligned than GPT-4o.[7]
