The Nemotron 3 family of open models — in Nano, Super and Ultra sizes — introduces the most efficient family of open models with leading accuracy for building agentic AI applications.

A personal recap of 2025 and a year of a new style of engineering.

The AI hype is over, and the industrial reality has begun. Here are some predictions for 2026, from the rise of disposable software to potential clashes over worker rights.

That judgment is the job of a senior engineer. As far as I can tell, nobody is replacing that job with a coding agent anytime soon. Or if they are, they’re not talking about it publicly. I think it’s the former, and one of the main reasons is that there is probably not that much spelled-out practical knowledge about how to do the job of a senior engineer in frontier models’ base knowledge, the stuff that they get from their primary training by ingesting the whole internet.

I wrote about JustHTML yesterday—Emil Stenström’s project to build a new standards compliant HTML5 parser in pure Python code using coding agents running against the comprehensive html5lib-tests testi...

I’ve started using the term HTML tools to refer to HTML applications that I’ve been building which combine HTML, JavaScript, and CSS in a single file and use them to provide useful functionality. I have built over 150 of these in the past year, almost all of them written by LLMs. This article presents a collection of useful patterns I’ve discovered along the way.

When people talk about AI in design, they often picture flashy visuals or generative art. But my own lightbulb moment happened at a less glamorous place: in an effort to solve this accessibility challenge under pressure. At UX Scotland earlier this year, I shared how AI helped me transform a messy, time-consuming process into something lean, structured, and scalable. Instead of spending weeks tweaking palettes and testing contrast, I had an accessible design system up and running in just a few days. In this article, I’ll explain how I did it and why it matters.
