Getting Started with AI

Start with a small task whose result you can check yourself.

Choose a task, explain it clearly and check the answer

How to Choose Your First AI Task: Start Small, Low-Risk, and Reviewable

Use four criteria to choose a small task whose result you can review.

AI Concepts

  1. AI ConceptsLLMs Are Not Knowledge Bases: Why Next-Token Prediction Can Produce Confidently Wrong AnswersUnderstand why fluent LLM output is not factual verification, and when AI applications need external data, retrieval, tools, validation, permissions, or human review.
  2. AI ConceptsTransformer Without the Math: What Attention and Embeddings Actually DoUnderstand Attention, Embeddings, and KV Cache without deriving matrices. Connect context, semantic search, RAG, and inference cost for AI application engineering.
  3. AI ConceptsWhat Exactly Is an AI Agent? From Chatbots to Closed-Loop Decision SystemsLearn why an AI Agent is more than an LLM with tools, and how Goal, State, Observation, Decision, Action, and Feedback form a closed-loop system.
  4. AI ConceptsWhat Is an AI Agent? Chat, Work, and Agentic Tasks ExplainedCompare chat, longer-form AI work, and agents by steps, tool use, external actions, and human control so you can choose the safer entry point.
  5. AI ConceptsHow Does Generative AI Produce Answers—and Why Can It Be Confidently Wrong?Learn why generative AI can produce fluent but incorrect answers, then use a simple boundary map to separate drafts, facts, and decisions that need verification.
  6. AI ConceptsHow AI Semiconductors Power Model TrainingAI training relies on matrix computation and specialized chips. Compare the roles of GPUs, TPUs, and ASICs, and how training needs differ from inference.
