OpenAI has officially unveiled its latest lineup of AI models — the GPT-4.1 series — which brings powerful upgrades. Whether you’re coding or analysing large documents, these new models are designed to handle more. The lineup includes three versions: GPT‑4.1, GPT‑4.1 mini, and GPT‑4.1 nano. Let’s delve into the details.
“These models are great at coding, instruction following, and long context (1 million tokens). Benchmarks are strong, but we focused on real-world utility, and developers seem very happy,” said OpenAI CEO Sam Altman on X (formerly Twitter).
Let’s dive into the details of the new GPT-4.1 models.
What’s new with OpenAI’s GPT-4.1?
One of the biggest highlights of GPT-4.1 models is their expanded context window. These models can work with up to 1 million tokens. This is a huge leap from GPT-4o models’ limit of 128,000 tokens. This means GPT-4.1 models can better understand long documents, large codebases, or detailed conversations without losing track of important details.

In addition to this, GPT-4.1 has gotten a major performance boost in coding. OpenAI says it delivers a 21.4% improvement over GPT-4o and a 26.6% jump compared to GPT-4.5 in coding-related tasks.
Also, on Scale’s MultiChallenge benchmark (a measure of instruction following ability), the new GPT‑4.1 scores 38.3%, a 10.5% increase over GPT‑4o, according to OpenAI.
