Guided Roadmaps
Follow a sequenced roadmap instead of piecing together disconnected tutorials.
A structured, progressive roadmap for developers seeking to master AI agents, covering Python foundations, LangChain, LangGraph, and private multi-agent RAG.
A comprehensive curriculum taking you from zero programming knowledge to professional data manipulation, mathematical visualization, and core ML model building.
Latest from the library
Start with recent code-first guides, or filter the library by the skill you are building.
Loop engineering explained: the five-step agent loop, why state must live outside the model, why a maker cannot grade its own work, and the four ways loops fail.
How WordPiece tokenizes words for BERT, the ## continuation marker, greedy longest-match encoding, and how it differs from BPE by merging on likelihood.
How Byte-Pair Encoding builds a subword vocabulary by merging the most frequent character pairs, how it encodes new words, and why GPT uses byte-level BPE.

What Students Say About Us
“The instructor explained clearly and its examples were easy to implement. I recommend it for introducing yourself into the latest advancements in transformers.”
“This is a nice hands-on video. The contents enhance the knowledge of fine tuning the model. I have also found that the 'theory' parts are very worth to learn.”
“The lecture is well-organized and delivered clearly, and easy to learn.”
