Getting started with AI in the browser has never been easier 🤗

Today we're releasing the Transformers.js #AgentSkill, your shortcut to running ML models in the browser.
It provides all the information your coding agent needs to add on-device AI to your web app.

Model: huggingface.co/google/trans...
Demo and Code: huggingface.co/spaces/webml...

TranslateGemma 4B by Google now runs 100% in your browser on WebGPU with Transformers.js v4.

55 languages. No server. No data leaks. Works offline.
A 4B parameter translation powerhouse, right in your browser.

Exciting news: this year I'm joining the organizing team of @uphillconf for the first time! 🎉
For the past two years, I've had the opportunity to give a talk, and each time it was a fantastic experience. That's why I decided to actively participate in the planning this year😊

That would be like hammering in a screw with a hammer and then complaining about how bad the hammer is.

I've seen several posts lately that share some edge cases in AI conversations where the AI makes mistakes. Of course, this is to show how bad AI still is.

AI is a tool. If it produces incorrect or unusable results, it is not the tool that is at blame, but the person who is using it incorrectly..

And please try it out, we'd love to hear your thoughts!

🤗 Transformers.js v4 preview is now available!

npm i @huggingface/transformers@next

And its huuuuge! I don't think a single line of code remained untouched😄.
New build system, monorepo structure, and tons of new features!

I have no idea what you're talking about. Those are clearly very happy, well-lit plants. In the event of contradictory statements, I reserve the right to take legal action..

We rearranged our apartment a bit and I had to move my office. A good time for some new paint and a few new plants🥰.

Promoting AI agents At the end of last year, AI agents really came alive for me. Partly because the models got better, but more so because we gave them the tools to take their capacity beyond pure reasoning. Now coding a...

I fully agree with DHH on this: "pure vibe coding remains an aspirational dream for professional work for me, for now. Supervised collaboration, though, is here today."

The lesson: AI coding tools work best when you establish clear structure upfront. The time you invest in architecture pays dividends in maintainability and makes AI assistance more effective, not less.

Fintrack, on the other hand, is a joy to work with. It has a robust foundation and architecture that makes it easy for both me AND the AI agent to know where features belong and how to reuse existing logic.

Components bloat, there's no clear structure for sharing logic or components, and the codebase becomes increasingly fragile.

For Pumpel, I ran a pure conversation experiment: How far could I get without even looking at the code? And yes, it works. But I don't like it. Worse, adding new features through prompting gets progressively harder.

I approached each project with different levels of "vibe coding."

For Fintrack, I wrote most code myself or carefully reviewed every line. I wanted to understand exactly where data is stored and how it flows through the system (for obvious reasons 😅).

All three started as spreadsheets I'd been using for months or years. Now they have proper UIs and additional features.

Why the upgrade? AI made it possible 🥰

But here's what I learned:

Over the Christmas holidays, I built three apps to replace my Google Sheets workflows:

- 𝗙𝗶𝗻𝘁𝗿𝗮𝗰𝗸: A budget tracker that imports bank transactions and allows us to categorize them
- 𝗣𝘂𝗺𝗽𝗲𝗹: A gym tracker
- 𝗛𝗮𝗯𝗶𝘁𝘀: A daily habit tracker

Mountains are unpredictable, and accidents happen even to the very best. My thoughts are with his wife and children..

When I was younger, I often went freeriding. Skiing in deep powder is one of the best feelings there is. But when our first child was born, I gave away my powder skis and never went in deep powder again.

Definitely not an easy post to write.
A friend of mine died in an avalanche a few days ago. He was a professional snowboarder who knew the mountains intimately.

[v4] Switch build system to use esbuild by nico-martin · Pull Request #1466 · huggingface/transformers.js

🚀 Transformers.js v4 update: We've migrated from webpack to esbuild.

Results:
- Build time: 2s → <200ms (10x faster)
- Bundle size: 10-50% smaller

Sometimes it's not about new features. It's about building a more robust architecture that makes everything else possible🔥.

However, this also means that if the session token is stolen, the attacker has a long window of opportunity to exploit it.
With passkeys, I can easily limit the lifetime of a session token to a few hours, as reauthentication is quick and easy.

Usually, a session token is created when you log in. This session token has a certain validity period. This can be an hour, a week, a month, etc. Normally, you would choose the longest possible period so that the user does not have to log in again and again.

Happy new year🍾

Passkeys aren't just more secure because of the tech, but also because of UX. Normally I would max out session tokens to avoid typing email/pw. Now with passkeys? Login is one click. Reauthenticate every time? Absolutely no problem..

Oh, and the best part? Built the entire thing in one train ride to the mountains and back.
That's maybe 2-3 hours total. Claude Code handled everything while I just described what I wanted.
We're living in a different era of building.
