Chapter 2 — The transformer, in plain English

Attention is a weighted way of deciding which tokens matter to each other. Once that clicks, Q, K, and V stop looking like magic. This chapter walks through the transformer one step at a time, then shows what changes during inference.

Scaled Dot-Product Attention Q (Query) K (Key) V (Value) MatMul Q · Kᵀ Scale ÷ √dₖ Mask (opt) Softmax MatMul × V Output
Each token scores what matters, turns those scores into weights, then carries the most useful context forward.

Why DeepMox

A chatbot gives you an answer.
DeepMox helps you finish a topic.

DeepMox is built for the longer job: deciding what comes first, organizing the material into progressive chapters, and keeping your progress between sessions.

Stop burning tokens just to build a course

DeepMox gives you a complete course library, Community Picks, and source-linked GitHub deep dives—plus monthly private AI chapters on Pro and Max.

You pay for the outcome. Not the tokens.

One chapter, three modes — wherever you are

You can't read a 14-minute essay on the GO Train, at the gym, or while washing dishes. DeepMox gives you the same chapter as an article, an 11-minute podcast, and an 11-minute video. Start on the laptop, finish on a treadmill — progress stays synced.

Don't just skim the answer. Finish the topic.

DeepMox gives you a clear 5–10 chapter path you can actually complete.

Read one chapter, listen to the next, and watch the recap later. Your progress stays synced, so every session moves you closer to finishing—not back to another prompt.

FAQ

Questions worth answering.

What is DeepMox?

DeepMox turns a subject you choose—or sources you already trust—into a chapter-by-chapter learning path you can read, listen to, or watch. Start with a curated public topic or use AI Create to build a private one, then keep your progress connected across chapters and devices until you finish.

How is DeepMox different from a chatbot or summary tool?

A chatbot gives you an answer, and a summary compresses a source. DeepMox organizes an entire topic: what comes first, how the chapters build on each other, which sources support them, and how your progress continues between sessions.

What can I add to AI Create?

Add HTTPS links or upload DOC, DOCX, PDF, TXT, MD, and MARKDOWN files. DeepMox organizes them into a private topic with progressive chapters. You are responsible for having the right to submit the materials you provide.

Are my AI Create topics private?

Yes. Private topics are available only through your account and are not published in the public library. DeepMox does not sell personal information or use private account content in public marketing without permission. Service providers may process data as needed to operate, secure, support, and improve the service, as described in the Privacy Policy.

Can I switch between reading, listening, and watching?

Yes. Each mode follows the same topic and chapter structure. You can move between formats and continue from your saved chapter progress on signed-in devices.

Can I cancel any time?

Yes. Cancel from your account or billing portal. Your paid access remains active until the end of the current billing period.

How does GitHub Trending work?

DeepMox tracks notable public repositories and surfaces a trending list. Selected repositories can become structured topics with source-linked chapters for eligible paid plans. Coverage and update cadence may change as the source and product evolve.

Stop context-switching.
Start actually finishing.

Start with a curated topic or create one from sources you already trust. DeepMox gives you one clear next chapter.
