The Prompt Engineering Studio

A prompt is a program written in plain language. Learn its anatomy, then bend the model's behaviour — examples, temperature, reasoning, structure, and guardrails.

Zero-shot vs few-shot

Examples are the cheapest fine-tuning that exists. Watch the same ticket-classification task with and without them.

Temperature & top-p, live

The model proposes candidates for the next word — sampling settings decide how boldly it picks. “Our quarterly revenue exceeded ___”

Greyed-out bars fall outside the top-p nucleus — they can never be sampled. Low temperature sharpens the distribution; high temperature flattens it.

Chain-of-thought

For multi-step problems, asking the model to reason before answering dramatically improves accuracy.

A team of 14 associates works 3 sandbox days/week. Each sandbox day produces 2 evaluated prompts. How many evaluated prompts after 4 weeks?
Model: 224 prompts — a confident guess, and wrong. It skipped the weekly structure.

Structured outputs — text → JSON

Your Week 4 sandbox task: pull clean JSON out of messy text so downstream systems can use it. Schema in the prompt, JSON out.

Unstructured input

Guardrails & negative examples

A production prompt also says what the model must not do. Try the injection attack against both prompts.
