Summary: Kimi K2 is China’s latest open-source AI model, beating GPT-4.1 and Claude Opus in coding and reasoning. In this tutorial, we’ll use it to build 3D browser games and visual simulations in minutes using just a single prompt.

🧰 Who is this useful for:

  • Developers seeking autonomous coding and debugging

  • Businesses automating complex workflows

  • Researchers analyzing large datasets or documents

  • Enterprises prioritizing cost-effective, secure AI

  • Creatives building games or interactive content

STEP 1: Access KIMI K2

Head over to KIMI and create a free account. Once logged in, you'll land on ChatGPT-style chat interface. Now locate the model selector and make sure “K2” is selected. 

That's it 🔥

Even on first use, it feels faster and more direct than GPT-4, ideal for builders who want speed and precision.

Step 2: Building with KIMI K2

Now you're good to go. You can just type what you want in the box where it says  “Ask anything”, and Kimi will generate the full output instantly.

You can build apps, games, 3D simulations, write scripts, summarize research papers, debug code, automate tasks, and so much more.

Here are a few examples to try:

1] 3D Rubik’s Cube you can actually control with your keyboard

Write a detailed prompt like:

“Create a 3D Rubik's Cube in the browser using Three.js or p5.js. Allow the user to rotate different layers of the cube with the arrow keys: Up/Down/Left/Right. Include scramble and reset functionality. Add realistic 3D animations and make the controls responsive to keyboard input. Write the entire code in one HTML file”

And click generate.

KIMI will generate entire code for:

→ Fully working Rubik’s Cube

→ Interactive keyboard inputs

→ Clean UI + animations

And you can preview the output instantly by just clicking on the “Preview” button on the top-right corner of the code block. 

2] Planet Visualizer

Similarly, prompt I use this time:

“Write code for a 3D solar system visualization in JavaScript using Three.js. Include 8 planets with accurate orbits, rotation speeds, and tooltips that display data on hover (e.g., distance from sun, gravity, orbital time). Allow zoom and pan with mouse. Make the scene interactive and educational”

Kimi will generate entire code for:

→ Interactive planets with hover tool tips

→ Zoom and rotate freely

→ Learn about orbital speed, gravity, and more
