Qwen3.5-4B-3D-Coder: Turn prompts into 3D Three.js web scenes (4B)

What it does

Qwen3.5-4B-3D-Coder is an independent retrained version of Qwen3.5-4B, trained on 4,146 example scenes. You give it a system prompt asking for the Three.js 3D library and a scene description; it writes one self-contained HTML and JavaScript file that a web browser opens as an interactive 3D scene. With the image add-on file loaded, it can also work from a reference image.

How to use it

Load the weights in a runtime: download a GGUF file (a compressed model format) and run it with llama.cpp's server, then open its web page, attach an image if you like, and send a prompt. In LM Studio, turn off multi-token prediction first. Full FP16 weights also load with Transformers. Use a randomness setting (temperature) of 0.6–0.8 and the source's Three.js system prompt.

Common use cases

• Ask for one self-contained HTML file showing a canal lock and weir complex with a central island, and you get a web page rendering that 3D scene.
• Attach a reference picture and type 'create this scene using voxels 3d', and you get a Three.js scene built from blocks that interprets the picture, not every detail.
• Describe an air traffic control tower with rotating radar and light signals, and you get a standalone HTML page meant to animate the tower, radar and beacon.
