You already know prompts

If you’ve used ChatGPT or any AI tool, you’ve written prompts:
“Write a joke about programming”
And when you want to improve results, you tweak the prompt:
“Write a funny joke about programming, make it witty not cheesy”

​
But real AI Applications are more complex

In production, your AI might:
  • Use multiple prompts working together
  • Call different models for different tasks
  • Adjust temperature, max tokens, and other parameters
  • Process inputs through several steps
  • Depend on context, rules, and configurations
Suddenly you’re not managing one prompt—you’re juggling an entire system of interconnected pieces.

​
Enter: Systems

A System captures all the moving parts that affect your AI’s behavior:
  • Your prompts (yes, plural!)
  • Model selection and parameters
  • Processing steps and logic
  • Any configuration that changes the output
Instead of tracking these pieces separately, a System bundles them into one testable unit.

​
A simple example

Even a basic joke bot has multiple variables: 
SYSTEM: Joke Bot

Inputs:
└── topic: "programming"

Configurations:
├── Model: "gpt-3.5" or "gpt-4"
├── Style: "dad-joke" or "witty"
├── Temperature: 0.5 to 1.0
└── (and any other settings that matter)

Output:
└── joke: "Why do programmers prefer dark mode?..."
Change any configuration, and you get different results. Systems let you test these variations systematically instead of guessing.

​
Why this matters

  • Everything in one place: No more scattered prompts and configs
  • Test combinations: See how different settings work together
  • Track what works: Know exactly which configuration is in production
  • Scale confidently: From single prompts to multi-step workflows

​
Your turn: build a joke bot in 5 minutes

The best way to understand Systems is to build one. We’ve created a simple example that shows the concept in action: → Try the Joke Bot Quickstart In just 5 minutes, you’ll see how even a simple AI task benefits from thinking in Systems rather than individual prompts.
Ready to level up from copy-pasting prompts? Systems are how teams build AI that’s reliable, testable, and scalable. Start small with the Joke Bot—the concepts will click immediately.
