OpenAI has begun rolling out the new GPT-4.1 and GPT-4.1 mini models to ChatGPT. GPT-4.1 is available to ChatGPT Plus, Pro, and Team subscribers, while the mini version is available to all users, including non-subscribers.
The company notes that GPT-4.1 is better at writing and debugging code and executes instructions faster than previous o-series models. With the introduction of the new models, OpenAI is also ending support for GPT-4o mini.
GPT-4.1 models first appeared in the API in April 2025, but the company was criticized for not having a security report. In response, OpenAI explained that GPT-4.1 is not an "advanced model" and therefore does not require separate verification, as is the case with more powerful systems.
