Start learning

ChatGPT

Understand how ChatGPT actually works — token prediction, instruction tuning, what it's great at, and where it confidently lies.

APIs

Understand APIs — how software talks to other software, what REST means, and how authentication, rate limits, and versions work in practice.

Prompt engineering

Learn prompt engineering — write clearer instructions, use structured outputs, chain steps, and squeeze better answers from any LLM.

Tokens in LLMs

Understand tokens in LLMs — how text is chunked, why context windows matter, and how tokens drive cost and latency.

AI hallucinations

Understand AI hallucinations — why language models invent facts, when it's most likely, and concrete ways to reduce them.

AI embeddings

Understand AI embeddings — how meaning becomes vectors, why similarity search works, and how embeddings power semantic search and RAG.

Machine learning

Get a working mental model of machine learning — training, generalization, overfitting, and how supervised and unsupervised methods differ.

Algorithms

Understand algorithms — what makes one efficient, how Big-O thinking guides design, and the classic patterns that show up everywhere.

Cloud computing

Understand cloud computing — what IaaS, PaaS, and SaaS actually mean, and why so much of the modern internet runs on three providers.

End-to-end encryption

Understand end-to-end encryption — what it guarantees, what it doesn't, and why governments keep pushing to weaken it.
