04How to Use Kimi K3: Examples and Walkthrough

Once you switch to K3, you can start giving it tasks. In the episode, the host tested it by asking it to build a website for an SEO agency. You can do the same or try other ideas.

For coding tasks, the free tier gives you a limited number of tokens. This means you can’t do huge projects for free. But for small tasks, it works well.

If you want faster replies, the host recommends using K2.6 for quick responses. K3 takes more time because it thinks more. For building something, K3 is the better choice.

  • Ask it to build a simple website.
  • Ask it to create a small game.
  • Ask it to generate a 3D scene.
  • Teach it a skill like ReMotion to make videos.

The host showed that K3 can create amazing things when using the API. It made games, 3D worlds, and even videos by combining ReMotion and KimiK.

05Results and Benchmarks from the Episode

The host tested Kimi K3 using the API, and it did very well on GoldieBench. In personal tests, it outperformed Fable 5 and GPT 5.6. It also beat Opus 4.8.

The host showed examples of what the model can create. It built games, created 3D worlds, and generated a video using ReMotion and KimiK.

These results show that K3 is a top-tier model. Even though it is free, it competes with paid models.

However, the free tier has token limits. The host found that K3 Swarm might not have enough tokens for free use. So for free, stick to standard K3.

The performance is impressive for a free model. You can achieve similar results if you follow the setup steps and manage your tokens.

06Tips, Limits, and Mistakes to Avoid

Using Kimi K3 for free has some tricks and warnings you should know.

  • Avoid using K3 Swarm on a free account – it runs out of tokens quickly.
  • Keep the context window on standard, not extra long. Extra long is premium-only.
  • Adjust the thinking effort. Max uses more tokens, so use it only when needed.
  • During peak times, free accounts might get paused. Use off-peak hours for more tokens.
  • Don’t try to host the open-source version locally on a basic computer. It needs a very powerful setup.

The host recommends using K2.6 when you need instant responses. K3 is for when you are actually building something.

If you run out of tokens, wait for off-peak hours or use K2.6 for simple tasks.
