OpenAI unveils GPT-4.1 series, promising better performance at lower cost

Key Takeaways

OpenAI unveiled the GPT-4.1 sequence promising main enhancements in coding, instruction following, and context understanding.
The GPT-4.1 fashions supply diminished latency and improved price effectivity in comparison with earlier variations.

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 few weeks.”

Shortly after his remarks, The Verge reported that OpenAI was making ready to launch its new AI fashions imminently. The trouble is a part of the corporate’s broader technique to reinforce its present choices forward of the anticipated GPT-5 launch in 2025.

In response 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 proportion 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 higher comprehension of complicated, multi-step directions, even when prompts embody formatting, tone, or sequencing constraints.

In relation to 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 data with higher consistency.

“We educated these fashions with a concentrate on real-world utility,” the corporate acknowledged in its announcement. “Shut collaboration and partnership with the developer neighborhood enabled us to optimize these fashions for the duties that matter most to their functions.”

Together with efficiency positive factors, the brand new fashions include diminished pricing. GPT‑4.1 is 26% inexpensive 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 brand new fashions at the moment are obtainable to builders by way of OpenAI’s API. With GPT‑4.1 delivering higher efficiency at decrease price, OpenAI introduced it can cease supporting the GPT‑4.5 Preview on July 14.
