OpenAI is releasing its GPT-4.1 and GPT-4.1 mini AI models in ChatGPT. The GPT-4.1 models should help software engineers who are using ChatGPT to write or debug code, OpenAI spokesperson Shaokyi Amdo told TechCrunch. GPT-4.1 excels at coding and instruction following compared to GPT-4o, according to OpenAI, but is faster than its o-series of reasoning models. The company says it’s now rolling out GPT-4.1 to subscribers to ChatGPT Plus, Pro, and Team. Meanwhile, OpenAI is releasing GPT-4.1 mini for free and paying users of ChatGPT. As a result of this update, OpenAI is removing GPT-4.0 mini from ChatGPT for all users. “GPT-4.1 doesn’t introduce new modalities or ways of interacting with the model, and doesn’t surpass o3 in intelligence,” said OpenAI’s Head of Safety Systems Johannes Heidecke in a post. “This means that the safety considerations here, while substantial, are different from frontier models.” Now, OpenAI is releasing more information about GPT-4.1 and all its AI models. OpenAI has committed to publish the results of its internal AI model safety evaluations more frequently as part of an effort to increase transparency. Those results will live in OpenAI’s new Safety Evaluations Hub, which it launched on Wednesday.
