Start with AI basics.Build the judgment to make things.

This is not a checklist of courses. It is a sequence of practice: build intuition, understand models, make a first system, then learn to make it reliable.

THE QUESTION THIS PAGE ANSWERS

ANSWER FIRST

What is the best way to start learning AI from scratch?

Start with what AI can do and why it fails, then move through prompts, models, and agents before RAG, evaluation, safety, and engineering. A path tied to real work builds more transferable judgment than memorizing a glossary.

DECISION RULE

Name the job you want to complete, then choose the shortest route that explains its important trade-offs.

TRY NEXT

Read “Choose the job you want AI to help with” first and use it to choose an entry point.

WATCH FOR

Do not chase every new tool at once. Establish one testable foundation before expanding the stack.

Read This Before You Build

A short orientation for choosing a useful starting point, building a study habit, and understanding why model fundamentals save time later. Read it when the AI landscape feels noisy or every tool looks equally urgent.

02Learning Methods

Learning With AI, Deliberately

A practical learning loop for using AI as a tutor without outsourcing your judgment: ask sharper questions, expose weak claims, break difficult material into pieces, and prove what you understood.

10 notes
03Part 0

AI Without the Fog

A plain-language first pass through what AI can do, how it produces answers, why it can sound certain while being wrong, and what is safe to hand over. No math required; the goal is a dependable first instinct.

45 notes
04Part 1

The Model Under the Product

Trace the path from training data and token prediction to chat interfaces, hallucinations, and mitigation choices. This chapter gives product decisions a technical reason instead of a trend-driven guess.

19 notes
05Part 2

The Harness Around the Model

Learn how context, prompts, tools, retrieval, output formats, and safety checks turn a model into a working system. Treat the harness as product architecture, not as a bag of prompt tricks.

61 notes
06Part 3

From Working Demo to Useful Product

Follow the decisions that separate an impressive demo from a dependable product: interaction loops, context budgets, memory, permissions, multi-agent collaboration, and recovery when the model loses the thread.

37 notes
07Part 4

Engineering Patterns for Reliable Agents

Read production-oriented patterns for context assembly, tool design, evaluation, long-running work, and sandboxing. The emphasis is on boundaries you can inspect when an agent succeeds for the wrong reason.

22 notes
08Part 5

When the Harness Improves Itself

Explore what happens when an agent can revise the scaffolding around its own work. The chapter is a guided tour of feedback loops, recursive improvement, and the controls needed before self-optimization becomes useful.

9 notes
09Part 7

Vibe Coding, With Guardrails

Use natural-language collaboration to move faster while keeping a human-quality bar: define the brief, control the loop, document decisions, and add safety gates before generated code becomes a dependency.

14 notes
10Special Topic

Taste Engineering: Make the Output Worth Keeping

Once AI can make something usable in minutes, taste becomes the differentiator. Practice seeing hierarchy, whitespace, restraint, and consistency, then translate those judgments into instructions a model can act on.

12 notes
11Special Topic

Interaction Engineering: Make the Product Usable

Go beyond visual polish and inspect the states people actually move through: loading, empty, error, undo, confirmation, and recovery. Learn to specify interfaces as behaviors an AI can implement and test.

10 notes
12Special Topic

AI Product Psychology: Design the Feeling

AI can be slow, uncertain, and opaque even when the underlying system works. Use psychology and product signals to calibrate trust, reduce waiting anxiety, and make the experience feel honest rather than magical.

19 notes
13Special Topic

Token Cost Engineering: Make the Numbers Work

Turn an AI usage bill into design information. Read token pricing, spot tier cliffs, understand agent cost growth, and reduce waste across syntax, semantics, architecture, and output without making the product feel smaller.

13 notes
14Programming Fundamentals

Data Structures Behind AI

Build programming intuition through systems you already know: message lists, caches, indexes, queues, and graphs. The point is not memorizing definitions; it is recognizing the structures inside AI-generated code and products.

13 notes
15Programming Fundamentals

Algorithms Behind AI

Connect complexity, search, sorting, recursion, graphs, and sampling to the mechanisms behind modern AI systems. Use the connections to estimate trade-offs and review code, even when an assistant wrote the first draft.

15 notes
16Part 6

Inside a Production Coding Agent

A source-led tour of a production coding agent: runtime, tools, memory, security, and extension points. Use the architecture as a set of questions for evaluating any coding agent you may rely on.

25 notes
17Special Topic

Inside DeepSeek Harness

Follow a plugin-based agent foundation from session logs to tool calls, compaction, inboxes, and sandboxed execution. This is an optional source-reading track for people who want to see the abstractions behind the interface.

29 notes
18Special Topic

Inside OpenAI Codex

Study how a coding agent makes context, approvals, tool execution, MCP, and sandboxing governable through its architecture. The practical takeaway is a checklist for putting security into the system itself.

32 notes
19Special Topic

Open Weights, Distillation & Local Runs

Separate open weights from open source, read licenses before deployment, and reason about distillation, hardware, and local serving. Finish with a grounded choice of what your own computer can actually run.
