Planned

Coming soon

These will slot into the reading order above as they're published.

How Models Learn

A beginner-safe bridge from training examples to model behavior before deeper optimization topics.

Why Models Follow Instructions

A plain-English explanation of instruction following before agent, tool, and system-prompt mechanics.

Context Windows And Their Limits

What fits into a model request, what gets left out, and why context limits shape AI product design.

System Prompts

How high-priority instructions shape model behavior without turning prompts into magic control panels.

Temperature And Sampling

Why generation can vary, what sampling controls do, and when randomness helps or hurts.

Structured Outputs

How AI systems ask models for JSON-like outputs and why validation still matters.
