What is Vibe Coding?

Vibe coding is a term coined by AI legend Andrej Karpathy to describe the fluid, iterative way of programming alongside Large Language Models (LLMs). It’s that magical flow state where you generate code, tweak it, generate more, and make incredible progress by working collaboratively with AI tools like ChatGPT and Claude.

But here’s the thing: while vibe coding is incredibly powerful and fun, it’s easy to get led astray. Without proper technique, you might find yourself with 200 lines of broken code, wondering what went wrong.

This guide will teach you the five essential techniques to master vibe coding and avoid common pitfalls.

The Five Pillars of Effective Vibe Coding

🎯 1. Good Vibes - Craft Quality Prompts

The foundation of successful vibe coding is spending time to create prompts you can reuse effectively.

Key principles:

  • Ask for conciseness: LLMs love to be verbose, adding unnecessary exception handlers and lengthy implementations
  • Specify current APIs: Always mention today’s date and request current best practices
  • Demand clean code: Explicitly ask for clean, readable solutions

Example prompt:

Today is June 23, 2025. I need to build a simple task manager API using current Python FastAPI best practices. 
Please provide concise, clean code without excessive error handling or verbose comments. 
Use APIs and patterns that are current as of this date.

✅ 2. Vibe but Verify - Multiple Perspectives

Never trust a single LLM response. The magic happens when you compare answers from different models.

The technique:

  • Ask the same question to both ChatGPT and Claude
  • Compare their approaches and solutions
  • Learn from the differences in their responses
  • Choose the best elements from each

Often, one model will be too verbose while another hits the sweet spot. Sometimes one misses the point entirely while the other nails it perfectly.

🔧 3. Step up the Vibe - Think Small, Build Big

This is where most developers go wrong. They ask for everything at once and get overwhelmed.

The golden rule: 10 lines at a time

Instead of generating 200 lines of code that might be broken, break your problem into bite-sized, independently testable chunks.

The process:

  1. Ask for the breakdown first: “Break this problem into 4-5 simple steps where each step can be tested independently”
  2. Generate function by function: Request small, focused implementations
  3. Test each piece: Verify every component works before moving on
  4. Assemble with confidence: Combine your tested pieces into a working solution

Example breakdown request:

I want to build a task manager API with FastAPI that can create, read, update, and delete tasks. 
Instead of giving me all the code, please break this down into 4-5 simple, testable steps where each step is about 10 lines of code and can be verified independently.

🔍 4. Vibe and Validate - Built-in Code Review

This technique mirrors the evaluator-optimizer pattern from AI system design.

How it works:

  1. Get your initial solution from one LLM
  2. Take that solution to another LLM (or even the same one)
  3. Ask for validation and improvement

Example validation prompt:

I asked for a Pydantic Task model and got this code:

[paste code here]

Please review this code and confirm:
1. Is this appropriate for a task manager?
2. Are there any bugs or issues?
3. Can it be more concise or better structured?
4. Does it follow current best practices for 2025?

This approach often catches problems early and results in cleaner, more robust code.

🎨 5. Vibe with Variety - Explore Multiple Solutions

Don’t settle for the first solution. When dealing with small chunks of code, ask for alternatives.

The approach:

  • Request 3 different solutions to the same problem
  • Ask for explanations of each approach’s rationale
  • Force the model to contemplate different ways of solving the problem

Example variety request:

Can you give me 3 different approaches for storing tasks in memory for this API? I want to see different data structures and explain the rationale for each approach. Keep each solution under 15 lines of code.

This technique often reveals better solutions and helps you understand the trade-offs between different approaches.

Putting It All Together: A Complete Example

Let’s see these principles in action by building a simple task manager API.

Step 1: Good Vibes - Initial Setup

Today is June 23, 2025. I need to build a simple task manager API using current Python FastAPI best practices. Please provide concise, clean code without excessive error handling or verbose comments. Use APIs and patterns that are current as of this date.

I want to start small and build incrementally. Don't generate a full application - just help me with individual components that I can test separately.

Step 2: Step up the Vibe - Get the Breakdown

I want to build a task manager API with FastAPI that can create, read, update, and delete tasks. Instead of giving me all the code, please break this down into 4-5 simple, testable steps where each step is about 10 lines of code and can be verified independently.

Expected breakdown:

  1. Define the Task data model with Pydantic
  2. Create basic FastAPI app with health check endpoint
  3. Implement POST endpoint to create tasks (in-memory storage)
  4. Add GET endpoint to retrieve all tasks
  5. Add PUT and DELETE endpoints for individual tasks

Step 3: Vibe but Verify - Multiple Models

Ask both ChatGPT and Claude for the Pydantic model:

Please create a simple Pydantic model for a Task with id, title, description, and completed status. Keep it under 10 lines and include basic validation.

Step 4: Vibe and Validate - Code Review

Take the best solution and ask for validation from another LLM.

Step 5: Vibe with Variety - Explore Options

Can you give me 3 different approaches for storing tasks in memory for this API? I want to see different data structures and explain the rationale for each approach. Keep each solution under 15 lines of code.

The Golden Rule: Always Understand Your Code

Here’s the most important principle that underlies all vibe coding: always ask for explanations of code you don’t fully understand.

Vibe coding is incredibly fun and productive, but if you lose track of what’s happening, it becomes frustrating when things inevitably go wrong. Stay connected to your code by requesting clear explanations of any unfamiliar patterns or implementations.

Common Pitfalls to Avoid

The 200-Line Trap

Never ask an LLM to generate large chunks of code all at once. If you find yourself with 200 lines of broken code, you’ve already lost the game.

Single-Source Syndrome

Relying on just one LLM is like getting directions from only one person. You might miss better routes or important warnings.

The Copy-Paste Cascade

Don’t just copy and paste without understanding. Each piece of generated code should make sense to you before you move on.

Conclusion

Vibe coding represents a fundamental shift in how we approach programming. When done right, it’s an incredibly powerful way to learn new frameworks, solve complex problems, and boost productivity.

The key is to embrace the collaborative nature of working with AI while maintaining your role as the architect and decision-maker. Use these five techniques to stay in control of the process and avoid the common traps that can make vibe coding frustrating.

Remember: vibe coding should be fun, productive, and educational. If it’s not all three, you’re probably doing it wrong.
