Users are discussing Google's open-source GNM (Generative Anthropometric Model), a parametric 3D statistical model for human head and face geometry.

The model emphasizes fine-grained, disentangled control over identity, expression, and head pose, and includes controllable internal structures like eyeballs, teeth, and a tongue. The repository offers multi-framework backend support, including NumPy, JAX, PyTorch, and TensorFlow, along with semantic parameter sampling capabilities.
