Briefings

A Qwen3.5-4B-GLB-3D-Coder model was trained to generate 3D assets for game engines like Godot, exporting Three.js scenes in GLB format. The first functional checkpoint was released on November 1, 2026, with training expected to conclude by November 2, 2026. English prompts such as 'Create a mana potion' successfully generated assets tested in Godot editors, though some generations required retries or code fixes. The model uses a system prompt from its card and operates with temperature 0.8, top-k 40, and top-p 0.95 settings.

Key points

• The Qwen3.5-4B-GLB-3D-Coder model generates Three.js scenes in GLB format compatible with Godot game engines.
• English prompts like 'Create a mana potion' successfully produced assets tested in Godot editor environments.

Context

This is the first functional checkpoint for a 4B parameter model designed to create 3D assets for game engines, with training expected to finish tomorrow evening.

Limitations

Some generations require retries or small code fixes; training is still running and will conclude tomorrow evening.
