I wanted to deploy my demonstration program, a local console application, to Foundry. The short answer is that without a front end (e.g. a Blazer Application) it made sense only to host the agents (and the tool) on Foundry, and leave the actual application on my local machine.

To do this, I consulted with Bruno Capuano and Jon Galloway, both of Microsoft. The result is a video that you can find here: Microsoft Agent Framework and Foundry Part 2.

Here’s Astra’s imagination of a future Zürich, generated by letting it control Blender and ElevenLabs with only a short one-shot prompt to go by:

Some other things Astra did today:

• It autonomously executed my complete August accounting, looking for documents in my email and drive and operating the accounting software in my browser.

• Created a beautiful and fun to play version of Tetris (which I am now slightly addicted to).

• Optimised the iOS version of Flashboard, my personal inbox-0-all-the-things task management app, to make it load and refresh much faster.

• Redesigned my homepage (I had to choose from dozens of gorgeous designs – it wasn’t easy).

Even more than all other current frontier models, Astra truly feels like a step change – intuitive, knowledgeable, opinionated. It’s fast and precise, and operates on my computer and in my browser at superhuman speed and confidence.

Feel the AGI 🖖

I’ve been a programmer for decades, but in the last few months I haven’t written a single line of code, even while creating more software than I ever have before. How? I moved to “factory mode”. I am now the manager of teams of agents that take my specs and directions and turn them into software. They are better at it than I ever could be.

Even more than I am impressed with the change for programmers like me, I am excited by the possibilities for everyone – creatives, business people, hobbyists, … anyone with great ideas – to establish their own factory and start building their own vision of the future.

That’s why I am teaming up with to teach the course Build Your Agentic Software Factory.

Through live workshops, Q&A sessions, an online community, and lots of materials and resources, we want to get as many of you running your own agentic factory and building the future. Join us!

b.t.w the course is on offer for VERY EARLY BIRDs at a massive ($200) discount through the end of the week.
