BitSparse: Compact Activation Storage for ReLU Feed-Forward Networks
Training economics matter, and 30% VRAM savings with near-zero overhead is material for builders scaling large models. Sparse activations are becoming standard with recent architectures, so this timing is right. The custom Triton kernels mean implementation friction, but the payoff justifies it if you're training or fine-tuning at scale. Test on your specific hardware and model.
