Domestic AI 3D large model Hi3D is here! Open source and commercially usable, PK takes down GPT-6

What happened: Hi3D released its V1.0 model code, a high-resolution geometry refinement model built on Sparc3D, available on GitHub and Hugging Face. The team also introduced Hi3D V3.0, described as the industry's first commercially usable 2048³ domestic AI 3D model. Key numbers: V1.0 trained on about 2 Why it matters: The team positions V1.0 as a production-validated base for developers and enterprises to research, deploy, and build on, while Hi3D Agent targets creators. The article contrasts Hi3D results with GPT-6 Astra outputs, which it says were less faithful to reference images.
