Neural Decode 3D is a browser based tool for exploring artificial intelligence neural network architectures in an interactive 3D environment. It includes 18 architectures, such as GPT 2, BERT, Vision Transformer, CLIP, Whisper, DeepSeek V3, ResNet, U Net, Mamba, and diffusion models. Users can also import their own models in ONNX format. The tool presents network structures as visual 3D representations that users can inspect to understand how their components are arranged. A typical workflow is to select an included architecture or import an ONNX model, then explore its structure in the browser. The site describes the experience as using WebGL, so access requires a compatible web browser and graphics support.
