Artificial intelligence demystified from absolute basics to advanced enterprise systems. 34 interactive modules covering fundamentals, applied machine learning in Python, and expert-level LLM architectures.
Go from absolute beginner to senior AI system architect. The curriculum is divided into three comprehensive tracks. We recommend following them sequentially, but you can jump to any section directly.
8 modules · AI fundamentals, prompt engineering, limitations, and ethics. No math or coding required.
Everyone uses it. Almost nobody can define it. In 28 minutes, you'll know more than 95% of people around you — with a clear mental model that sticks.
The single concept that powers every modern AI — explained with cats, dogs, and one beautifully simple visual. No equations. Real understanding.
From your morning alarm to your evening scroll — you're already surrounded by AI. Map every invisible moment.
Prompting isn't magic — it's a skill. Learn to ask better questions, craft clearer instructions, and get dramatically better results from any AI tool.
AI isn't just text anymore. Explore computer vision, speech recognition, and generative AI — and what they can (and can't) do.
Hallucinations, bias, and failure modes — knowing where AI breaks is just as important as knowing where it works. Critical thinking for the AI age.
Privacy, deepfakes, job disruption, accountability. The hard conversations that everyone using AI should be part of — explained fairly.
Put everything together. Design and build a personal AI assistant using the concepts, tools, and frameworks you've learned across all seven modules.
12 modules · Python basics, data preparation with pandas, regression, tree classifiers, evaluation metrics, and API deployments.
Learn the essential Python syntax, variables, lists, dicts, functions, and control flow needed for machine learning.
Load datasets, filter anomalies, perform exploratory data analysis, and master data cleaning using pandas in the browser.
Deep dive into linear and logistic regression models, cost functions, gradient descent, and predictive analytics.
Build decision trees, learn how bagging creates random forests, and how gradient boosting iteratively minimizes prediction errors.
Discover hidden patterns without labels. Master K-Means clustering and Principal Component Analysis (PCA) dimension reduction.
Build a feedforward neural network in Python. Master weights, biases, activation functions, and backpropagation.
Learn image feature extraction, filter kernels, edge detection, and Convolutional Neural Networks (CNNs).
Process text into numeric vectors using TF-IDF, bag-of-words, word embeddings, and Recurrent Neural Networks (RNNs).
Integrate generative AI APIs, manage contexts, engineer system prompts, and construct basic RAG pipelines.
Measure what actually matters. Master confusion matrices, precision, recall, F1 scores, and ROC curves.
Transition from local Jupyter notebook cells to production. Wrap your trained machine learning model in a FastAPI endpoint.
Build a production-ready customer churn prediction pipeline. Clean data, train tree models, tune thresholds, and export a deployment function.
14 modules · Deep attention mechanisms, transformers, RLHF, sparse gating (MoE), diffusion models, cognitive agents, LoRA fine-tuning, and vector retrieval.
Master the encoder-decoder neural network structure that forms the backbone of all modern LLMs.
Inspect self-attention and multi-head attention mechanisms, query/key/value matrices, and positional encodings.
Trace the lifecycle of LLMs: pre-training on raw text, supervised fine-tuning (SFT), and aligning via RLHF and DPO.
Understand sparse gating networks, MoE routing, token capacity limits, and how sparse MoE models run efficiently.
Deconstruct generative image models. Learn forward noise processes, reverse denoising UNets, and classifier-free guidance.
Align vision and language spaces using contrastive learning (CLIP), cross-attention layers, and unified token vocabularies.
Explore positional interpolation, RoPE rotation, flash attention, and needle-in-a-haystack context retrieval limits.
Empower models to interact with external APIs, execute SQL queries, and make math calculations via structured JSON calls.
Design autonomous agents using ReAct loops, planning frameworks, reflection systems, and scratchpad memory.
Train open-weight models on custom datasets efficiently using low-rank adapters and 4-bit quantization (QLoRA).
Maximize token throughput. Explore KV caching, speculative decoding, model quantization (AWQ/GPTQ), and vLLM servers.
Architect enterprise-grade RAG. Learn HNSW graphs, similarity metrics, chunking strategies, and hybrid search pipelines.
Secure and monitor LLMs. Address prompt injection, configure guardrails, implement semantic caching, and monitor cost.
Design and deploy a coordinated team of specialized AI agents working together to solve complex, multi-stage problems.
No math. No coding required. No assumed knowledge. Every concept is explained from scratch with real-world analogies that actually stick.
Flip cards, quizzes, mini-games, and timelines built into each lesson. You don't just read — you explore and discover.
Covers the AI tools shaping the world right now — ChatGPT, image generators, AI agents — with honest explanations of what they can and can't do.
