OpenAI has launched GPT-4.1 and GPT-4.1 mini in ChatGPT for all paid users, offering enhanced performance for coding and instruction-following tasks. GPT-4.1 is now available in the model selector, while GPT-4.1 mini replaces GPT-4o mini as the default fallback for free users.

ACB News | May 15, 2025 – Sydney OpenAI has officially launched GPT-4.1 and GPT-4.1 mini models in ChatGPT, expanding its offering of specialized tools tailored for coding, instruction-following, and everyday developer tasks. The update, announced on May 14, 2025, brings the popular GPT-4.1—previously only available through API access—directly into ChatGPT for all paid users.

GPT-4.1 has been widely praised by developers since its release in April, thanks to its superior performance in web development and precision instruction handling. The model now provides a compelling alternative to OpenAI’s earlier coding-focused models, such as o3 and o4-mini, for routine development needs.

Starting immediately, GPT-4.1 is available in the “more models” menu for ChatGPT Plus, Pro, and Team subscribers. Enterprise and Education (Edu) users will gain access in the coming weeks. Usage limits for GPT-4.1 are aligned with those of GPT-4o for paid users.

In parallel, OpenAI also introduced GPT-4.1 mini, a lightweight and efficient variant that replaces the previous GPT-4o mini. This smaller model offers noticeable improvements in instruction-following, coding ability, and general intelligence. GPT-4.1 mini will now appear in the “more models” menu for paid users and act as the default fallback for free users after exceeding their GPT-4o usage limits.

Both models—GPT-4.1 and GPT-4.1 mini—have undergone standard safety evaluations, and performance benchmarking data was previously published alongside their API release. Full evaluation results are now available in OpenAI’s newly launched Safety Evaluations Hub.

This update further strengthens OpenAI’s focus on model specialization and developer utility, setting the stage for continued innovation across AI-powered professional and enterprise workflows.
