Join the RAG Pack for a free masterclass on Agents! I'm looking forward to this one soooo much! @JayAlammar , @joshuastarmer, @ChrisJMcCormick, @SerranoAcademy, and I worked our asses off to make this one extra special. Oh, and you might see one or two visuals from "An Illustrated Guide to AI Agents" 😉

The eBook version of "An Illustrated Guide to AI Agents" is live! More than 300 illustrations and the code for building an Agent from scratch. @JayAlammar and I did WAY too much for this book, and I'm glad we did. We learned so much from our previous book, and we did all we could to make this book even more special. You will learn how to build an Agent entirely from scratch through text, code, and figures. We wanted to give you the complete educational experience and focused heavily on a single narrative throughout the entire book. The physical edition should land in a couple of weeks, and I'm excited to get my hands on it! Amazon: amazon.com/Illustrated-Guide… O'Reilly: oreilly.com/library/view/an-…

Encoder-free architectures are super interesting ;)
Ever wonder what makes Gemma 4 12B so unique? In this 2 minute overview series, learn what an encoder-free model is and how Gemma 4 12B processes image and audio inputs differently from the rest of the Gemma family!

This was a fun demo to make 😀
What does it take to run 3, 5, or even 10 concurrent instances of Gemma 4 locally? We've open-sourced a demo letting you run multiple models side-by-side on your hardware. Gemma 4 26B A4B easily runs 10+ concurrent requests on a MacBook Pro M4 Max at 18 tokens/sec per request.

If only every foundational LLM lab would publish such a guide with their model releases.
A Visual Guide to Gemma 4 With almost 40 (!) custom visuals, explore the new models from Google DeepMind. We explore various techniques, ranging from Mixture of Experts and the Vision Encoder all the way up to Per-Layer Embeddings and the Audio Encoder. Link below 👇
