In their own words
Hi3D
Hi3D is an AI image-to-3D tool that turns images into models using Math Magic’s Sparc3D and Ultra3D models. It supports both single-image and multi-view generation, along with text-to-3D, AI texturing, 3D relief generation, and a tool for dividing characters into printable parts. Exports include FBX, GLB, OBJ, STL, and USDZ, and models can be sent directly to Bambu Studio and OrcaSlicer. The wider integration list includes Snapmaker, Creality Print, ElegooSlicer, ComfyUI, and Blender. Developers and enterprises can use its Open Platform API; API operations are priced by model and resolution, with one credit listed at $0.020. The Free plan includes 100 lifetime credits, up to 10 asset generations, one concurrent task, and storage for seven models; those models are public under CC BY 4.0. Paid plans include private and commercial use, and the listed pricing note says paid plans start at $19.90/mo. Hi3D Scan supports video capture or gallery upload for model reconstruction. Platforms include Android, iOS, web, and API.
Stable Fast 3D
Stable Fast 3D turns an image of an object into a textured, UV-unwrapped 3D mesh. Stability AI describes the model as generating a 3D model from one image in under one second. It expects a 512 × 512 pixel input, applies a delighting step, and predicts roughness and metallic material parameters. The official code example saves the result as a GLB file. The repository includes custom nodes and an example workflow for ComfyUI, and API access is available. Documented inference options include CUDA, CPU, and experimental Mac MPS; Windows support is marked experimental. Default settings use about 6 GB of VRAM for one image. Stability AI identifies game and VR developers and professionals in retail, architecture, and design among its intended users.
