    # Bug Hunting with Kimi K2 and OpenCode

    Kimi K2 can solve complex 3D Math problems in Minecraft!
    Previously, [Kimi K2 built a Minecraft clone](https://gist.github.com/cedrickchee/fceb67886e5c005503d3d1840eb63fc8#ai-model-kimi-k2) in just a few minutes. It's playable in my browser. But, it's hard to control and move the player around the voxel world due to a few bugs in the 3D world model. So I take this chance to stress test Kimi K2 by giving it harder tasks such as solving tough bugs.

    Prompts below.
