NVlabs/tiny-cuda-nn
Lightning fast C++/CUDA neural network framework
Provides fully-fused MLP kernels and multiresolution hash grid encodings optimized for neural field applications, with optional JIT compilation that fuses encoding, network, and custom operations into single CUDA kernels for 1.5–5x speedups. Offers a JSON-configurable C++ API supporting various encodings, losses, and optimizers, with Python bindings for PyTorch integration and lower-level CUDA RTC APIs for embedding models directly into application kernels.
