In long-context scenarios, KV cache surpasses model weights as the primary memory bottleneck. TurboQuant focuses on quantization compression, OSCAR reduces storage via sparsity, and EpiCache lowers memory usage through optimized caching strategies. Though distinct, these approaches can be combined to collectively alleviate memory pressure.
