Releasing GPT-4.1 in ChatGPT for all paid users
Since its launch in the API in April, GPT-4.1 has become a favorite among developers—by popular demand, we’re making it available directly in ChatGPT. GPT-4.1 is a specialized model that excels at coding tasks. Compared to GPT-4o, it's even stronger at precise instruction following and web development tasks, and offers an alternative to OpenAI o3 and OpenAI o4-mini for simpler, everyday coding needs. Starting today, Plus, Pro, and Team users can access GPT-4.1 via the "more models" dropdown in the model picker. Enterprise and Edu users will get access in the coming weeks. GPT-4.1 has the same rate limits as GPT-4o for paid users.
GPT-4.1 mini is a fast, capable, and efficient small model, delivering significant improvements compared to GPT-4o mini—in instruction-following, coding, and overall intelligence. Starting today, GPT-4.1 mini replaces GPT-4o mini in the model picker under "more models" for paid users, and will serve as the fallback model for free users once they reach their GPT-4o usage limits. Rate limits remain the same. Evals for GPT-4.1 and GPT-4.1 mini were originally shared in the blog post accompanying their API release. They also went through standard safety evaluations. Detailed results are available in the newly launched Safety Evaluations Hub.
