AI Terminal Course

Understand what your AI tools are actually doing. 14 hands-on modules. Terminal only. No videos, no slides.

Quick Start

# Works instantly — no API key needed:
npx ai-terminal-course

# Or install globally:
npm install -g ai-terminal-course
ai-terminal

That's it. The course runs in demo mode by default with simulated API responses. To use real OpenAI APIs (optional, ~$10 total):

mkdir -p ~/.ai-terminal-course
echo "OPENAI_API_KEY=sk-your-key" > ~/.ai-terminal-course/.env

What You'll Learn

Tier 1 — Build Something Now

1. Your First LLM Call — Make a real API call, understand what comes back
2. Prompt Engineering — Few-shot, chain-of-thought, templates that work
3. Streaming Responses — Real-time token-by-token output
4. Structured Outputs — Get JSON back, validate with schemas
5. Tool Calling — Let LLMs call your functions

Tier 2 — Understand the Engine

6. Tokens, Cost & Context — How LLMs see text, what it costs, why they forget
7. Embeddings & Semantic Search — Turn text into vectors, find similar things
8. RAG: Chat With Your Data — Retrieval-augmented generation + chunking strategies
9. Agentic Patterns — ReAct, planning, multi-step reasoning

Tier 3 — Ship to Production

10. Evals & Testing — Test suites, quality metrics, LLM-as-judge
11. Guardrails & Safety — PII detection, content filtering, prompt injection defense
12. Cost Optimization & Caching — Model routing, semantic caching, 90% cost reduction
13. Monitoring & Observability — Logs, traces, alerts, incident response

Tier 4 — Graduate

14. Capstone: Ship It — Build a complete Document Q&A system

Who This Is For

• You can code (any language)
• You're comfortable with the terminal
• You have zero AI/LLM knowledge (perfect starting point)

Demo Mode vs Real Mode

| | Demo Mode | Real Mode | |---|---|---| | Setup | npx ai-terminal-course | Set OPENAI_API_KEY | | Cost | Free | ~$10 total | | Responses | Simulated (labeled) | Real OpenAI API | | Best for | Exploring the course | Full learning experience |

Demo mode responses are clearly labeled [DEMO MODE - simulated response] so you always know what's real.

Time & Cost

• Duration: ~7 hours (14 modules, ~30 min each)
• API cost: Free (demo mode) or ~$10 (real APIs)
• Prerequisites: Node.js 18+
