Tripo H3.1

Tripo H3.1 is a high-fidelity image-to-3D and text-to-3D generation model developed by Tripo AI (VAST). Released alongside the speed-oriented P1.0 model, H3.1 is specifically designed for production-ready environments where detailed visual fidelity and structural accuracy are prioritized over rapid concept generation. The model aims to produce dense, complex meshes suitable for close-up renders, hero assets, cinematic scenes, and high-quality 3D printing workflows.

Architecture and Capabilities

Moving away from token-by-token generation, Tripo H3.1 natively builds geometry in 3D probabilistic space, ensuring that shape and structure are created cohesively. The model is capable of generating high-density geometry containing up to 2 million polygons, allowing it to preserve micro-details such as cloth folds, sharp armor edges, and fine surface features. Furthermore, H3.1 outputs fully configured PBR (Physically Based Rendering) materials, including base color, normal, roughness, and metalness channels. The model also supports retopologized quad mesh outputs, making the generated assets natively animation-ready and easily riggable without extensive manual cleanup.

Use Cases and Prompt Guidelines

Tripo H3.1 is highly suited for game development, interactive media, and product visualization, maintaining physical scale consistency across different generated assets. When utilizing text-to-3D features, the model demonstrates strong adherence to style and subject modifiers, allowing creators to dictate whether the output should be geometry-only or fully textured, as well as specify standard or detailed geometry qualities. For optimal results in image-to-3D generation, providing multiple view reference images helps the model accurately align structural features and improve overall texture consistency.
