Master AI Prompt Engineering
Through Coding Challenges

Practice writing precise prompts that make AI generate the exact code you need. Like LeetCode, but in reverse - you write the spec, AI writes the code.

No credit card required • Unlimited challenges • All AI models included

Why LeetPrompt?

In the AI era, knowing how to communicate effectively with language models is as important as coding itself

Step 1

Get Challenge

You're given initial code that needs improvement. Your job is to write a prompt that guides the AI to transform it correctly.

Initial Code

func sum(a, b int) int {
    // TODO: implement
    return 0
}

Expected Result

func sum(a, b int) int {
    return a + b
}

Frequently Asked Questions

Everything you need to know to get started with LeetPrompt

Why don't you accept my better solution?

This challenge is not about code quality. It's about your ability to bend the LLM's to your will. We encourage you to think creatively and explore different approaches. Remember, the goal is to improve your AI communication skills, not to produce the most optimal code.

Which LLMs are supported?

We support multiple AI models including GPT-4, Claude, and other leading language models. Each model has different scoring multipliers based on their capabilities - more advanced models have higher multipliers, making it more challenging but more rewarding to achieve high scores.

How do I get started?

Simply click "Start Challenge" to begin! You'll be presented with coding problems that need specific implementations. Your job is to write prompts that guide the AI to produce the correct code. Start with easier problems to learn the platform, then progress to more complex challenges.

What makes a good prompt?

Great prompts are clear, specific, and concise. They provide enough context for the AI to understand the task without being unnecessarily verbose. Focus on describing the desired behavior, edge cases, and any specific requirements. Practice and feedback will help you improve your prompting skills over time.

How is scoring calculated?

Your score is calculated using our comprehensive formula: 60% accuracy (how well the AI output matches the expected solution), 20% efficiency (prompt length and computational cost), and 20% clarity (how unambiguous your prompt is). Model multipliers and difficulty bonuses can further adjust your final score.
