@deepseek_ai DeepSeek-V4.1-Flash-1017 is insane for 3D This is one-shot result, no harness, not using any other software like Blender, all in code without any external assets, just Three.js Look at the details, remember this is one-shot, it's also running real smooth, no frame drops as well. This is insane, i cannot believe we are getting this with a Flash model
