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

The Verge described GPT-4.1's release as "mark[ing] a pivot in the company's release schedule".[1] HackerNoon praised the model as "a HUGE win for developers", and stated that it challenged the advantages of Gemini 2.5 Pro's longer context window and Claude 3.7 Sonnet's strong reasoning capabilities.[6] Zvi Mowshowitz described GPT-4.1-mini as an "excellent practical model".[7] However, he criticized OpenAI for not doing enough safety testing, saying that he "hate[s] the precedent this sets".[7]

Two research teams - one led by Oxford University researcher Owain Evans, the other based at the AI red-teaming startup SplxAI - independently found evidence that GPT-4.1 could be more misaligned than GPT-4o.[8]
