Unlocking Longer Generation with Key-Value Cache Quantization
KV-cache quantization just cut memory overhead by up to 10x. Here's why that changes the game for long-context inference.
Why it matters
KV-cache quantization is a foundational efficiency breakthrough that directly expands context windows and reduces inference costs—critical for competitive model deployment. This technical advance affects how companies architect their inference infrastructure and which models become cost-viable for production workloads.
