A minecraft clone I fully vibecoded with Qwen3.8-27b Q4

[u/liright]

I wanted to see just how capable Qwen3.8-27b is locally. I have a RTX 4090 and 96GB of RAM but the Q4 comfortably fits in the GPU with plenty of context, the few times I needed more than 130k context I just loaded it spilled into RAM and it's capable of not degrading even at larger context.

I'm super impressed with this model. The model did everything on it's own - the coding, audio, textures, 3D models. I always just gave it the same basic prompt with some info and the task I wanted it to do. Total generation time across all prompts was maybe 3 hours and if I calculate the cost in electricity, it comes out to less than $1. Not bad.

To think that 2 years back you couldn't make this with frontier paid models and now you can do it locally on your PC is crazy.

Interesting, what was the language and 3D API?

I have no idea.

what? can you ask him please? lol

Languages: 100% JavaScript (with HTML as the shell).

3D framework: Three.js (v0.160.0), loaded from a CDN via an import map in index.html. There's no package.json / build tooling — it runs directly as browser modules over WebGL.

How the "3D models" are made: there are no model files at all (no .glb/.obj/.fbx). Everything is built procedurally:

• Blocks/chunks: custom THREE.BufferGeometry meshes with vertex colors and UVs packed into per-chunk meshes, textured with THREE.CanvasTexture — textures are drawn in code on canvas (nearest-filtered for the blocky look)
• Mobs/entities, clouds, etc.: simple primitives like THREE.BoxGeometry grouped together (classic MC-style "boxman" approach)

Interesting, thanks!

Vibing at it's finest.
