Hands-on With Claude Design Anthropic just launched Claude Design, a new research-preview product for generating interactive prototypes, slide decks, and more. I took it for a spin by designing a new analytics screen for my habi...

I tried Claude Design to design a new feature in my app.

It speeds up UI prototyping over vibe coding prototypes.

The prototypes are interactive and it’s possible to run them side-by-side.

The hand-off to Claude Code is janky but it’s quite new so it’ll improve.

Check the post for details.

There are many use cases that do not require the performance improvements provided by new generations and would instead benefit from maintaining previous performance at a lower price point.

I hope Google will soon offer an "Extra Lite" Gemini model.

If you are a reflexive naysayer or a pessimist, know that, and force yourself to find a way in to wonder, surprise and delight.

If you are an optimist who gets very excited and tends to assume that everything will improve: know that, and force yourself to mind real cautionary tales.

My (hypothetical) SRECon26 keynote One year ago, Fred Hebert and I delivered the closing keynote at SRECon25. Looking back on it now, I can hardly connect with how I felt then. Here's what I'd say one year later.

The best advice I can give anyone is: know your nature, and lean against it.

I released my first mobile app on iOS and Android.
There is such a contrast between how fast building with AI is, and how slow the mobile app release process is.
I wrote about the whole experience in this post.

Why I care more about your SLM than your LLM A review of the paper Too Big to Think: Capacity, Memorization, and Generalization in Pre-Trained Transformers," (Barron & White, 2025)

A very easy to understand review of the paper Too Big to Think: Capacity, Memorization, and Generalization in Pre-Trained Transformers,".

Large models simply memorize the training data.
Smaller models learn the rule because they don't have enough "brain space" to memorize every individual answer.

The Benefits of Bubbles We are in an AI Bubble: the big question is if this bubble will be worth it for the physical infrastructure and coordinated innovation that result?

Ben Thompson argues that while AI is obviously in a bubble, it will create long term benefits in the form of investments in chip fabs in the U.S. and power plants.

This is similar to how we got dark fiber and train tracks as infrastructure out of the internet and railway bubbles.

Quick intro to Claude Skills

Simplicity is the point.

The most significant limitation of MCP is token usage

Almost everything an MCP can do, can also be handled by a CLI tool instead. LLMs know how to call cli-tool --help, which means you don’t have to spend many tokens describing how to use them

What happens to a driving Waymo when AWS us-east-1 goes down? 😅
Is everything processed locally?
It’s an Alphabet company, so if something is remote, I’d expect it to be on GCP or Google internal platforms, but with external dependencies, isn’t every product 6 degrees of separation from us-east-1?

The Majority AI View - Anil Dash A blog about making culture. Since 1999.

Okay, for the folks who asked: here's the majority AI view, writing up the reasonable, thoughtful view on AI that the vast majority of people in tech hold, that gets overshadowed by the bluster and hype of the tycoons trying to shill their nonsense. anildash.com/2025/10/17/t... Please share!

This is the first article I read about spec-driven development and this is a good introduction.
I thought spec meant PRD, but it’s more of a detailed technical design.
As a profession, we were not good at documentation before AI, so this will not suit many orgs.
And it seems overkill in most cases.
