OpenAI launched three new models — GPT-4.1, GPT-4.1 mini, and GPT-4.1 nano — in its API this month, featuring larger context windows (up to 1 million tokens) and improved performance in coding and instruction over GPT‑4o and GPT‑4o mini.

“To this end, the GPT‑4.1 model family offers exceptional performance at a lower cost,” said the company.

“For tasks that demand low latency, GPT‑4.1 nano is our fastest and cheapest model available; it delivers exceptional performance at a small size with its 1 million token context window.”

Only available via the API, GPT‑4.1 arrives as OpenAI rivals like Google and Anthropic released, respectively, Gemini 2.5 Pro, which also has a 1-million-token context window, and Claude 3.7 Sonnet. Also, Chinese AI startup DeepSeek launched an upgraded V3.

“OpenAI’s ambition is to create an “agentic software engineer,” as CFO Sarah Friar put it during a tech summit in London last month.

GPT-4.1 costs $2 per million input tokens and $8 per million output tokens. GPT-4.1 mini is $0.40/million input tokens and $1.60/million output tokens, and GPT-4.1 nano is $0.10/million input tokens and $0.40/million output tokens.

“And then the third that is coming is what we call A-SWE. We’re not the best marketers, by the way, you might have noticed. But Agentic… https://t.co/oFd0SKGu3S

Over 2,000 K-12 schools in 100 countries have installed Brisk’s Chrome extension, which allows teachers to write lesson plans, tests, and presentations, and grade work, since its launch in February 2025.

With 40 tools, the platform uses generative AI, computer vision, and other features.

The most popular tool in the stack, “Targeted Feedback,” uses generative AI to read student essays (on Google Docs) and create comments tailored to age, a grading rubric, or other standards. Before sharing anything with students, teachers can review and edit the comments.

“The existing edtech stack as we know it, which is around 140 different tools that the average teacher in the U.S. uses in a given school year, is not ready for AI,” said Brisk’s CEO and founder, Arman Jaffer.

The San Francisco-based Brisk raised $15 million in funding with investors such as Bessemer Venture Partners, Owl Ventures, South Park Commons, and Springbank Collective.

The funding will be used in part to build more tools, and in part to expand to more platforms. A Microsoft integration, aimed at the many Microsoft shop schools, is planned for autumn 2025.
