A service that turns any website into clean Markdown or structured data for models. It can search, scrape, crawl a whole site and even click through a page.
A small Microsoft utility that converts PDF, Word, PowerPoint, Excel and other files into Markdown that is easy to hand to a language model.
An open coding agent for the terminal with a desktop app. It is not tied to one provider: plug in whichever models you have.
A toolkit for spec-driven development: principles and a spec first, then a plan and tasks, and only then code. Works with several coding agents.
OpenAI's lightweight coding agent that runs in the terminal and works on your project's code. Written in Rust.

A large collection of ready-made LLM apps: agents, RAG systems and skills for coding agents. Every template can be run and taken apart piece by piece.
A free 21-lesson Microsoft course that goes from generative AI basics and prompting to working applications. Each lesson ships with code.
Code for Sebastian Raschka's book: you build a GPT-like model in PyTorch step by step, then pretrain and finetune it. The best way to see how an LLM works inside.
An animation engine Grant Sanderson uses to make 3Blue1Brown videos, including the well-known neural network ones. It is not an AI library but a tool for explaining math and ML visually.
A 12-week course on classic machine learning: 26 lessons and 52 quizzes. The foundation that makes modern models easier to understand.
A three-part LLM roadmap: fundamentals, the LLM Scientist (building models) and the LLM Engineer (building apps). Topics come with Colab notebooks.
A Microsoft course of 18 lessons on building AI agents: tools, memory, planning, multiple agents. Code examples live in the code_samples folder.
More than 60 PyTorch implementations of research papers with notes next to the code: transformers, optimizers, GANs, reinforcement learning. The website shows code and notes side by side.
A curated list of skills, subagents, plugins, status lines and tools for Claude Code. A handy map of the ecosystem around the coding agent.
A catalog of AI agent use cases by industry: healthcare, finance, education, retail. Each use case links to an open-source project.
More than 90 projects on LLMs, RAG and agents, sorted by difficulty from beginner to advanced. Each project has its own write-up and code.
A free Hugging Face course on agents in four units: fundamentals, the smolagents, LlamaIndex and LangGraph frameworks, agentic RAG and a final benchmark assignment.
More than 40 runnable notebooks with RAG techniques, from basic retrieval to advanced setups. Each one has the idea, the code and references.
Code for every example in Jay Alammar and Maarten Grootendorst's book Hands-On Large Language Models. Twelve chapter notebooks, from tokens and transformers to RAG, multimodality and fine-tuning.
A curated list on large language models: milestone papers, open models, training and inference frameworks, courses and books. A good reference for a first look at the field.
Andrej Karpathy's video course: you code neural networks from scratch, from backpropagation up to a GPT-style language model. Lectures come with notebooks.
Code notebooks for François Chollet's Deep Learning with Python (third edition, on Keras 3). Runs on JAX, TensorFlow or PyTorch. Legacy notebooks for the two earlier editions are included.
A tiny autograd engine with a small neural net on top and a PyTorch-like API. Very little code, yet it shows exactly how backpropagation works.
Companion materials for Chip Huyen's book AI Engineering: table of contents, chapter summaries, study notes, prompt examples and case studies. The book covers adapting foundation models to real tasks.
Code for the first edition of Sebastian Raschka's Python Machine Learning (2015): classic algorithms in NumPy and scikit-learn, from the perceptron to clustering. A newer edition lives in a separate repo.
Companion materials for Chip Huyen's Designing Machine Learning Systems: table of contents, chapter summaries, an MLOps tools overview and a resource list. There is no code, the book is about design decisions.
