Hi3D Opens Source Its AI 3D Model V1.0

BEIJING, Oct. 23, 2026 /CourierPR/ -- Hi3D, a company that specializes in AI-driven 3D modeling, has made a significant stride in the industry by releasing its production-validated AI 3D model, Hi3D V1.0, as an open-source project. This move marks a pivotal moment in the democratization of 3D creation tools, allowing developers, researchers, and enterprises to access and utilize the model for free.

Formerly known as Sparc3D, Hi3D V1.0 gained recognition in 2025 for its high-resolution 3D geometry modeling capabilities. The company has now expanded the training dataset from approximately 500,000 to two million curated 3D assets, significantly enhancing the model's practical usability in real-world production workflows. This expansion has enabled the model to achieve the highest multi-view fidelity and detail richness scores in reported evaluations, alongside a 90% slicing success rate.

The open-source release of Hi3D V1.0 is part of the company's broader vision to build foundational infrastructure for AI 3D creation. By providing a shared technical foundation, Hi3D aims to foster innovation across various applications, including 3D printing, product and e-commerce, industrial design, VR/AR/XR, animation and film, and more. Enterprises and developers can now explore private deployment, integrate the model into existing workflows, and build specialized products and services under the applicable license.

In addition to the open-source release, Hi3D has also introduced Hi3D V3.0, the first commercially available AI 3D model with 2048³ voxel resolution. This advanced model delivers finer geometric detail, more coherent complex structures, and improved texture quality, further solidifying Hi3D's position as a leader in the field.

To simplify workflows and lower technical barriers, Hi3D has also introduced Hi3D Agent, a creator-first 3D agent that combines large language models (LLMs) reasoning and tool use with Hi3D's proprietary 3D model. This integration makes Hi3D's capabilities available to external agents and applications, streamlining the creation process for creators.

Furthermore, Hi3D has announced a reduction of over 50% in credit consumption, making 3D creation more accessible to a broader range of creators. This move underscores the company's commitment to empowering more individuals to bring their ideas to life through innovative 3D technologies.

With the release of Hi3D V1.0, the company is setting a new standard for open-source AI 3D models, paving the way for a more collaborative and innovative future in the 3D creation space.
