OpenAI has officially rolled out its new GPT-4.1 collection, inclusive of GPT-4.1, GPT-4.1 mini, and GPT-4.1 nano, to ChatGPT users. The corporation says that the new models convey first-rate improvements in coding, education following, and lengthy-context comprehension.
"These models outperform GPT-4o and GPT-4o mini across the board, with principal profits in coding and preparation following," OpenAI wrote on its blog post.
Getting admission to these models on ChatGPT will most effectively be available to paying customers. In a post shared on X (previously Twitter) on May 14, OpenAI additionally confirmed that its modern flagship model, GPT-4.1, is now staying on ChatGPT. The announcement follows a broader launch of the GPT 4.1 own family on OpenAI's API platform a month in the past, wherein builders can already combine and take a look at the 3 variations—full, mini, and nano. However, with the ultra-modern replacement, the models at the moment are to be had by all ChatGPT customers, besides loose users.
What is new in GPT-4.1?
OpenAI claims that the GPT-4.1 appreciably outperforms its predecessor GPT-4o in regions like coding and education following. The version is designed with a larger context window, which helps up to at least one million tokens. Because of this, it may systemize and preserve more statistics right now. It also comes with an expertise cutoff of june 2024. GPT-4o's know-how cutoff is october 2023.
OpenAI has shared benchmarks on its authentic weblog publish that say that the GPT-4.1 indicates a 21 percent consistent absolute improvement over GPT-4o in software engineering duties and is 10.5 percent better in instruction following. OpenAI says the version is now tons better at maintaining coherent conversations throughout a couple of turns, making it more powerful for real-world programs such as writing assistance, software development, and customer support. "While benchmarks offer precious insights, we educated these fashions with a focal point on actual global software. Near collaboration and partnership with the developer network enabled us to optimize these models for the duties that are most relevant to their applications," OpenAI says.
The mini and nano variations are scaled-down variations aimed toward offering high overall performance with decreased price and latency. GPT-four. 1 mini is reported to reduce latency by almost half while costing 83 consistent with costing much less than GPT-4o. Nano, the lightest of the 3, is OpenAI's most inexpensive and quickest version yet and is ideal for simpler duties like autocomplete or text category.
"These models push performance ahead at each point on the latency curve," OpenAI writes.
Who can use it?
Handiest ChatGPT Plus, Pro, and Group customers may be able to get the right of entry to GPT-4.1. Unfastened-tier customers won't be getting the new model, at a minimum for now. As a substitute, they will maintain the usage of GPT-4o, which OpenAI says will step by step comprise improvements seen in the more modern models.
GPT-4.1 is likewise to be had via the API for builders and businesses, with OpenAI positioning it as a more value-green and effective alternative to preceding generations. The new pricing consists of huge discounts: GPT-4.1 entry costs start at $2 per million tokens, and the nano model is to be had from just $0.10 per million tokens. Prompt caching reductions have additionally been increased to seventy-five percent to make repeated queries lower priced.
The release of GPT-4.1 comes as OpenAI has started phasing out earlier models. GPT-4.5 Preview, a research-centered release, became deprecated within the API on april 14, 2025. GPT-4, the model that powered ChatGPT Plus for the reason that march 2023, has already been discontinued. Whilst GPT-4.1 isn't always replacing GPT-4o internal ChatGPT, many of its abilities are being folded into the GPT-4o experience. But, for customers and developers searching out 5bf1289bdb38b4a57d54c435c7e4aa1c overall performance, direct entry to GPT-4.1 via API or a ChatGPT subscription is now the way to move.
