Two weeks ago there were over 2,000 plugins waiting in queue to be manually reviewed for the popular markdown editor Obsidian. The introduction of coding agents and interest for Obsidian as a virtual brain led to an explosion of new plugins being written for the platform, and the review process up until last week was…

The past few months I have held full-day workshops in agentic engineering for hundreds of developers. And what strikes me every time is how little most people know about how AI models really work. And there’s a good reason for it. I still haven’t encountered any good management-level introduction videos that explain how these models…

GPT-5.5 is different. GPT-5.5 is the first model trained at OpenAI’s flagship Stargate site in Abilene, Texas, one of the supercomputing facilities funded by the $500 billion partnership between OpenAI, SoftBank, and Oracle. The site runs on Oracle Cloud Infrastructure, is powered by NVIDIA’s GB200 Blackwell systems, and is purpose-built to train frontier AI at…

Be prepared to forget everything you have learnt about how to maximize AI productivity by maximizing token usage. In the new token economy less is more, and the new top skill for AI engineers in 2026 will be how to optimize token usage to save cost. When OpenAI launched GPT-5.5 last Thursday they doubled the…

Two years ago in the summer of 2024 OpenAI launched their first ChatGPT desktop app for macOS. Back then we didn’t have agentic engineering, so the entire app was hand coded using the Apple Swift framework. It took five additional months for OpenAI to ship the ChatGPT desktop app for Windows, but that app was…

Last week I visited HumanX in San Fransisco, one of the largest AI conferences in 2026 with over 9,000 attendees, 500+ speakers and 400+ journalists. The conference is centered around deep-dive interviews with industry leaders and I visited 36 sessions over four days. It took the entire weekend to summarize all my notes. From the…

This is what I wrote in Tech Insights 2025 week 28 (July):“In 9-12 months I predict the models will be able to run autonomously for several hours, probably more, and will be able to produce much higher output quality than is possible today. Let’s say that a subscription for such a model costs $5,000 per…

Last week Google launched what most LinkedIn experts and AI newsletters summarized as one of the biggest technical leaps in years. The Rundown AI wrote: “Google Research introduced TurboQuant, an algorithm that compresses AI model memory over 6x without any retraining”. And LinkedIn AI (with 13,800 followers) wrote: “Google just made AI models smaller. Without…

After nearly five years of development and over $80 billion of investments, Meta is closing down the Metaverse on June 15. Metaverse was a constant race for a technology that never arrived: no-one felt comfortable standing up for hours with a big heavy device strapped on their face, so Meta began to design services for…

Things are moving fast now. Two months ago Anthropic launched a new feature called “Cowork”, where Claude works autonomously within a sandbox environment on your computer with access to your files and various connectors. You choose the files Claude can work with, but you need to be careful – if prompted the wrong way there…
