Give it a question and it: - Creates an explicit action plan - Reasons about the next step - Chooses and calls tools - Inspects each result - Updates the plan and repeats It does not stop after one tool call. The agent keeps looping until every step in the plan is complete. Along the way, it can ask clarifying questions, use local context, delegate focused research to an isolated Wikipedia subagent, and collect sources. Once the plan is done, it turns the evidence into a cited response and downloadable research paper. The incredible part is the size: just 2.6B parameters. That makes LFM2.5 seriously fast on-device with WebGPU, while still being capable enough to plan, reason, use tools, and finish multi-step objectives. The model, agent loop, and inference pipeline all run locally. No inference server, no account, and prompts and outputs stay in the browser. Small models are not just autocomplete. They can be agents at the edge. https://www.instagram.com/p/DbDQMAKs_yl/ instagram:2026-07-21:After using windows basically my whole life, it was on-device AI performance tha... Tue, 21 Jul 2026 12:00:00 GMT instagram After using windows basically my whole life, it was on-device AI performance that finally pulled me over to apple. And honestly? Never regretted it for a second. I bought this M3 MBP in feb 2024. 2.5 years later I've never owned a laptop this long and there's still no end in sight. Runs like day one, every single day. The stickers tell the story 🚀 What's the longest you've kept a laptop? https://www.programmier.bar/podcast/deep-dive-211-transformers-js-mit-nico-martin podcast:2026-07-07:Transformers.js mit Nico Martin Tue, 07 Jul 2026 12:00:00 GMT podcast In dieser Folge begrüßen wir einen alten Bekannten in der programmier.bar: Nico Martin, Machine Learning Engineer bei Hugging Face und gern gesehener Podcast-Gast und programmier.con-Speaker. https://www.instagram.com/p/DZPjY3qDFIJ/ instagram:2026-06-06:After my week started in Bucharest, it ended at a rock concert in Oslo.

Sort of. #ReactNorway took place at Rockefeller, a legendary Oslo concert hall that's hosted everything from Norwegian metal festivals to international headliners. And they leaned fully into it. The stage, the lighting, the crowd energy: this wasn't a conference room with a projector. It felt like a show. One track, no escape, full attention. It's my favourite conference format, full stop. Everyone shares the same experience, hallway conversations are actually about the talks, and there's zero FOMO. I spoke about my in-browser Jarvis demo, which was very well received. And it sparked some great discussions how far on-device AI has already come! Always a good sign. My time in Oslo was short but sweet. Just long enough to soak up the city a little (and the surrounding nature). One thing I was not prepared for: sunrise at 4am, sunset at 11pm. My body still hasn't recovered. Thanks for the warm welcome, Oslo, and huge thanks to Aina, Nebojsa and the whole Team🤘 https://www.instagram.com/p/DZJ5p7ejFkG/ instagram:2026-06-04:CEE's biggest tech conference... ...also: Bucharest is great.

This week I had the pleasure of speaking at @devtalksro, the largest tech conference in Central and Eastern Europe, and honestly, it showed. The expo floor alone was something else: from Google all the way to students showcasing their own robot projects. That range of scale, from industry giants to the next generation of builders, is exactly what a healthy tech community looks like. I didn't get to see as many talks as I would have liked: my morning was taken up by my own session, where I walked through the story behind my in-browser Jarvis and the ideas that shaped it. In the afternoon I got to go even deeper in a roundtable workshop, diving hands-on into the agent loop with the participants. Both were a blast. What I didn't expect was how much Bucharest had to offer. A charming old town, the striking architecture of the communist era, and a very much alive modern city vibe. Definitely underrated. Great connections, great energy, great city. Thanks for having me, DevTalksRomania 🙌 https://www.programmier.bar/podcast/spezialfolge-google-i-o-2026-aus-mountain-view podcast:2026-06-02:Google I/O 2026 aus Mountain View Tue, 02 Jun 2026 12:00:00 GMT podcast Die Google I/O ist für viele Entwickler:innen vor allem durch ihre Ankündigungen bekannt – doch wie fühlt sich die Konferenz eigentlich vor Ort an? Darüber sprechen Jan und Dennis mit Nico Martin, der in diesem Jahr nach Mountain View gereist ist. Nico berichtet von seinen Eindrücken auf dem weitläufigen Google-Gelände, den großen Keynotes und den zahlreichen Möglichkeiten, direkt mit den Teams hinter Chrome, Gemini und anderen Google-Produkten ins Gespräch zu kommen. Natürlich geht es auch um die großen Themen der diesjährigen Google I/O. Die Runde diskutiert die aktuellen Gemini-Ankündigungen, den hohen Produktionsaufwand hinter den Keynotes und die Frage, wie viel davon wirklich neu war. Besonders spannend waren für Nico die Produkt-Demos vor Ort, darunter die neue Google-Brille, die er selbst ausprobieren konnte. Außerdem werfen Jan, Dennis und Nico einen Blick auf die Rolle von Entwickler:innenkonferenzen im Allgemeinen. Sie vergleichen die Google I/O mit Formaten wie der Google Cloud Next und den lokalen Google I/O Connect Events und diskutieren, für wen sich ein Besuch lohnt. https://www.youtube.com/watch?v=A_6UOxQSvvY video:2026-05-27:How Transformers.js Works: AI Models in JavaScript, Explained Wed, 27 May 2026 12:00:00 GMT video Transformers.js brings state-of-the-art machine learning to JavaScriprt. In this intro, I explain the mental model behind Transformers.js: tensors, neural networks, ONNX, quantization, model loading, preprocessing, postprocessing, and the pipeline() API. We also look at what happens under the hood for text-generation and depth-estimation, and why one high-level API can support many different AI tasks. https://www.instagram.com/p/DYrhHPAjNZf/ instagram:2026-05-23:Back from my first Silicon Valley trip.

First of all: a great chance for Joshua Lochner and me to have a little Transformers.js offsite. We'd met in Amsterdam almost exactly a year ago, but that was before I joined Hugging Face. Remote work is great, but meeting in person every now and then? Priceless. 𝗗𝗮𝘆𝘀 𝟭 𝗮𝗻𝗱 𝟮: 𝗚𝗼𝗼𝗴𝗹𝗲 𝗜/𝗢 Finally meeting so many internet friends in person. Years of comments, DMs, and GitHub threads and suddenly you're grabbing coffee with them. That alone was worth the flight.. On the tech side: lots of Gemini in everything. More deep integration than groundbreaking innovation, honestly. The exception: Gemini Omni. All-modal in, all-modal out. That one gave me pause. Personal highlight: the Gemma 4 sessions, including our own live demo of a Reachy Mini robot powered by Transformers.js and Gemma 4. Seeing on-device WebML power a robot in real time is exactly why I do this work 😊 Dinner with the LiteRT.js team was one of the best conversations of the trip. On paper, Google's web ML inference library is a competitor to Transformers.js. In practice? Not even close to competitive in spirit. We all want the same thing: make AI inference in the browser better. Rising tide lifts all boats. 𝗗𝗮𝘆 𝟯: 𝗦𝗮𝗻 𝗙𝗿𝗮𝗻𝗰𝗶𝘀𝗰𝗼 The city genuinely surprised me. Stunning scenery, Golden Gate, and the Google I/O After Hours event in the evening.. great connections made. 𝗢𝗻𝗲 𝗺𝗼𝗿𝗲 𝘁𝗵𝗶𝗻𝗴: 𝗪𝗮𝘆𝗺𝗼 In Europe, self-driving cars still feel distant. In the Bay Area, they're just... normal. Smooth, safe, easy, whether on an open road or in rush hour. The future is already here. 10/10. Can't wait to come back 😊 https://www.instagram.com/p/DYUGe5ODL5D/ instagram:2026-05-14:Biggest learning from @uphill_conf '26: being a speaker is so much easier than b... Thu, 14 May 2026 12:00:00 GMT instagram Biggest learning from @uphill_conf '26: being a speaker is so much easier than being an organizer 😅 After the last two years on stage, I switched sides this year. Nine months of prep, a lot of group chats, and one very humbling ropes course at the speaker event in Grindelwald later, we pulled it off! over 300 attendees enjoyed a sunny and inspiring day on the Gurten. This year with a second stage and a focus on valuable insights, optimized solutions, and lessons learned from running AI apps in production to share with the developer community. A few highlights from the talks: Imanol Schlag gave us a behind-the-scenes look at Apertus, a fully open research project from Switzerland. can't wait for 1.5. Omar Sanseviero walked through what Gemma4 means for on-device AI. New benchmarks, solid technical depth. @charlie__g closed the day with creative and experimental AI interfaces, demoed live on stage. perfect way to end a conference. And my on-stage-contribution this year? I got to moderate the open source panel with Ben Burtenshaw, @jonnyburger, Panos Vagenas and Romain Jourdan. Three things stuck with me: 💡 On OSS business models: AI makes everything grow exponentially. Without a scalable model underneath, that growth becomes a problem. 💡 On OSS security: security by obscurity was always the wrong approach. The more interesting question is how to leverage AI for security itself. 💡 On OSS contribution overload: Large OSS projects are drowning in PRs, most of them one-prompt, no real thought behind them. One reframe that landed: stop treating PRs as contributions and start treating them as signals. A spike of PRs around one topic might point to a real solution worth exploring. Thanks to everyone who joined us on the Gurten. see you next year 🏔️ And a huge thanks to Matthias, Christian, Johann, Roland, Christof, Marco and Tobias for organizing this with me. #UphillConf #OpenSource #AI #Conference https://neciudan.dev/takeaways/browser-ml-at-scale-with-nico-martin podcast:2026-04-26:Browser ML at Scale with Nico Martin Sun, 26 Apr 2026 12:00:00 GMT podcast This week, I spoke with Nico Martin, open source ML engineer at Hugging Face working on Transformers.js, and a Google Developer Expert in AI and web technology. Nico's path is unusual — he studied to become a teacher, worked as a ski instructor and a windsurf instructor, taught himself web development by building sites for friends, and went freelance for years before joining Hugging Face about six months ago. The role pulls together his obsession with progressive web apps, on-device AI, and Transformers.js — a library he was already building demos with before version one even shipped. In this episode, we cover how Transformers.js actually runs models in the browser, what an ML model really is under the hood, how tokenizers and quantization work, why ONNX matters as a runtime-agnostic standard, where WebGPU fits next to WebAssembly, and what the Prompt API in Chrome means for the future of in-browser LLMs. https://chromewebstore.google.com/detail/transformersjs-gemma-4-br/dhaknnnkcdkjhcclchmnfdhddoehoool project:2026-04-23:Gemma 4 Browser Assistant Thu, 23 Apr 2026 12:00:00 GMT project An on-device AI assistant that runs entirely in your browser using WebGPU and Transformers.js.

Zum anderen erleben PWAs dank der neuen WebGPU-APIs und dem Hype um AI eine Art Renaissance. Aber was sind eigentlich Progressive Web Apps und was unterscheidet sie von „normalen“ Webseiten oder Bookmarks auf dem Homescreen? Und macht die Art der Anwendung für Endnutzer:innen wirklich einen Unterschied? All diesen Fragen und vielen weiteren gehen Dennis und Jan nach und sprechen dafür mit Nico Martin, Google Developer Expert fürs Web. Dabei geht’s nicht nur um APIs, Browser-Implementierungen und Webstandards, sondern auch darum, was User:innen von Webseiten erwarten und welche UX für sie relevant ist. https://pdf.nico.dev/ project:2024-06-04:Ask my PDF Tue, 04 Jun 2024 12:00:00 GMT project A Webapp that uses Retrieval Augmented Generation (RAG) and Large Language Models to interact with a PDF directly in the browser. https://www.git-installer.com/ project:2022-11-22:Git Installer Tue, 22 Nov 2022 12:00:00 GMT project Install and update WordPress themes and plugins directly from your Git repository via GitHub, Gitlab or Bitbucket. https://speed-wheels.nico.dev/ project:2022-03-30:SpeedWheels BLE Car Wed, 30 Mar 2022 12:00:00 GMT project A toy car based on an Arduino Nano RP2040 that communicates over Bluetooth Low Energy and can be cntrolled with a webapplication that uses the Web Bluetooth API. https://workingdraft.de/521/ podcast:2022-03-16:Revision 521: WebBluetooth, WebUSB und WebNFC Wed, 16 Mar 2022 12:00:00 GMT podcast Nico Martin, Google Developer Expert und Webtech-Nerd, erklärt in dieser Revision Schepp und Peter alles zu WebBluetooth, WebUSB und WebNFC! https://md.nico.dev/ project:2021-12-17:[md.edit] Fri, 17 Dec 2021 12:00:00 GMT project A web based markdown editor that uses modern progressive web app features to provide a great, cross-platform editing experience.
