3D AI Studio vs PartCrafter

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.

PartCrafter is a free, open-source model that generates multiple 3D parts and objects from a single RGB image. It can handle individual objects and complex scenes, producing distinct meshes with meaningful part structure without requiring a pre-segmented image. Its architecture represents parts with disentangled latent tokens and uses hierarchical attention to pass information within and across parts. Local inference scripts can remove backgrounds and optionally apply style transfer to adapt real-world photos toward the rendered-image domain used for training. An optional vision-language feature can suggest the number of parts; Gemini is the default provider, and the provider architecture can be extended. Pretrained object-level and scene-level weights are hosted on Hugging Face. Installation is from the GitHub repository in a Python environment, and inference requires a CUDA-enabled GPU with at least 8 GB of VRAM. The linked Hugging Face demo is paused, though its page says users can ask the authors to restart it. The repository lists an MIT license and provides the software as-is, without warranty.
