OpenAI has formally launched its next-generation mannequin lineup—GPT-4.1, together with GPT-4.1 mini and GPT-4.1 nano—that includes main enhancements in coding, instruction following, and context understanding.
The rollout follows an announcement earlier this month from OpenAI CEO Sam Altman revealing the corporate’s plans to launch the o3 and o4-mini fashions “in a couple of weeks.”
Shortly after his remarks, The Verge reported that OpenAI was making ready to launch its new AI fashions imminently. The effort is a part of the corporate’s broader technique to reinforce its present choices forward of the anticipated GPT-5 launch in 2025.
According to OpenAI, the brand new GPT-4.1 fashions outperform earlier variations throughout key benchmarks. The flagship mannequin, GPT-4.1, scores 54.6% on SWE-bench Verified for coding duties—a 21.4 share level enchancment over GPT-4o.
On instruction following, GPT-4.1 additionally exhibits main positive factors. It outperforms GPT-4o by 10.5 factors on the MultiChallenge benchmark, and demonstrates better comprehension of advanced, multi-step directions, even when prompts embody formatting, tone, or sequencing constraints.
When it involves context dealing with, all three fashions can deal with as much as 1 million tokens, up from 128,000 within the earlier technology. OpenAI says the fashions carry out reliably throughout the complete context window, retrieving and processing the related info with larger consistency.
“We trained these models with a focus on real-world utility,” the corporate acknowledged in its announcement. “Close collaboration and partnership with the developer community enabled us to optimize these models for the tasks that matter most to their applications.”
Along with performance positive factors, the brand new fashions include lowered pricing. GPT‑4.1 is 26% cheaper than GPT‑4o for median queries, and GPT‑4.1 nano is OpenAI’s quickest and most inexpensive mannequin thus far, in response to the corporate.
The new fashions at the moment are accessible to builders through OpenAI’s API. With GPT‑4.1 delivering better performance at lower cost, OpenAI introduced it should cease supporting the GPT‑4.5 Preview on July 14.
