3D AI Studio vs Stable Fast 3D

3D AI Studio generates 3D models from text prompts or uploaded images. It also provides AI image generation and editing, texturing, quad remeshing, animation tools, and a built-in render engine. Flow is a node-based canvas for chaining image, text, 3D, video, and batch steps into reusable workflows. Users can choose Prism engines or external engines including Meshy, Tripo, Rodin, and Hunyuan. Exports include FBX, GLB, OBJ, STL, 3MF, USDZ, and BLEND for Unity, Unreal Engine, Blender, or 3D printers. New users receive free credits without a credit card; image-to-3D and text-to-3D cost 20 credits each, while Texture AI, Remesh, and LOD generation are free. The REST API uses pay-as-you-go credits, asynchronous polling, and a default limit of three requests per minute per key. Generated assets are described as private, user-owned, and commercially usable. Browser and API access are available.

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.
