What's AI-assisted coding?
You describe what you want, and the AI writes the code.
What it is
Intent, not syntax
- You describe the outcome, AI writes the code.
- Fast iteration: try, see it, adjust.
- You steer, review, and correct.
What it isn't
Not magic
- Not skill-free. You still need judgment.
- Not hands-off. You own the result.
- Not just for engineers.

The jargon, explained
Machine Learning
A subset of AI where systems learn patterns from data to make predictions or decisions.
LLM
Large Language Model. Trained on huge amounts of text to understand and generate human-like language.
Agent / Agentic AI
AI systems that take actions, use tools, and make decisions toward a goal with minimal human input.
Prompt Engineering
The instructions and context you give an AI model. Good prompts get better results.
Context Window
The amount of text a model can consider at once, both what you send and what it remembers.

Right model, right job
You wouldn't put a PhD on data entry, or hand a junior the system architecture.
Haiku
Fast, cheap, eager. Give it the high-volume, well-defined work.
- High-volume tasks
- Automation
- Chatbots
Sonnet
Your reliable workhorse. The default for most production work.
- Production APIs
- AI agents & RAG
- Business logic
Opus
Deep expertise, slower and pricier. Save it for the genuinely hard problems.
- Complex architecture
- Advanced coding
- Research & analysis

Same ask, different answer
Me: "Hey AI, go do a thing."
Haiku: "OK, I'll go do the thing."
Sonnet: "OK, but let me think about the best way to do the thing."
Opus: "Before we do the thing, are you sure it's the right thing to do?"
