OpenAI has launched its subsequent technology of LLMs—the GPT-4.1 household, comprising GPT-4.1, GPT-4.1 mini, and GPT-4.1 nano. These new fashions surpass the capabilities of GPT-4o and GPT-4o mini, showcasing vital developments in coding, instruction following, and lengthy context comprehension, all whereas providing decrease prices and diminished latency.
The brand new fashions can be found instantly by way of the API, with GPT-4.1 priced at $2.00 per 1 million enter tokens and $8.00 per 1 million output tokens. GPT-4.1 mini prices $0.40 and $1.60, respectively, and GPT-4.1 nano is priced at $0.10 and $0.40. OpenAI can be rising the low cost for repeated context use to 75% for these new fashions.
“GPT‑4.1 is a major step ahead within the sensible software of AI,” OpenAI stated in its announcement. The fashions function an expanded context window of as much as 1 million tokens and incorporate data as much as June 2024.
In coding proficiency, GPT-4.1 achieved a 54.6% rating on the SWE-bench Verified benchmark, an enchancment of 21.4 share factors over GPT‑4o. Its means to observe directions additionally noticed good points, scoring 38.3% on the Scale MultiChallenge benchmark, a ten.5 share level improve over GPT‑4o. For understanding lengthy sequences of data, GPT-4.1 reached a brand new excessive of 72.0% on the Video-MME benchmark.
The GPT-4.1 household additionally emphasises effectivity. GPT-4.1 mini “matches or exceeds GPT‑4o in intelligence evaluations whereas decreasing latency by almost half and decreasing value by 83%”, OpenAI additional stated.
Within the 4.1 household, GPT-4.1 nano is the quickest and least expensive mannequin out there for duties that want fast responses. It has a 1 million token context window and performs nicely in duties like classification and autocompletion.
These developments are anticipated to facilitate the event of extra succesful AI brokers that may independently deal with duties.
“Builders can now construct brokers which can be extra helpful and dependable at real-world software program engineering, extracting insights from massive paperwork, resolving buyer requests with minimal hand-holding, and different advanced duties,” the corporate acknowledged.
It is very important word that GPT-4.1 can be accessible solely via the API. OpenAI clarified that lots of the enhancements in instruction following, coding, and intelligence have been step by step integrated into the most recent model of GPT‑4o inside ChatGPT.
OpenAI additionally introduced the upcoming discontinuation of GPT-4.5 Preview within the API, scheduled for July 14, 2025. This resolution was made as a result of “GPT‑4.1 provides improved or related efficiency on many key capabilities at a lot decrease value and latency”.
Early testing by varied corporations has yielded constructive outcomes. In line with the corporate, Windsurf reported that GPT-4.1 scores “60% increased than GPT‑4o on Windsurf’s inside coding benchmark”, resulting in “sooner iteration and smoother workflows”.
Furthermore, Qodo discovered that GPT-4.1 produced higher options in 55% of circumstances for code opinions. BlueJ famous a 53% extra correct efficiency on advanced tax eventualities, whereas Hex noticed almost two instances extra enchancment on difficult SQL evaluations. Thomson Reuters skilled a 17% enchancment in multi-document overview accuracy, whereas Carlyle reported 50% higher retrieval from massive, data-rich paperwork.
