LightInferra™ Optimized Inference is designed to restore—and then expand—GPU efficiency under long-context workloads by proactively managing KV cache movement across memory tiers. Instead of reacting to KV page faults after the GPU already stalled, LightInferra uses Sub-Linear Attention Prefetch via the OpenKVCache API to keep the next-needed KV blocks ready before they’re touched by attention. This enables materially higher sustained QPS/TPS, more predictable SLAs, and improved utilization of expensive GPU fleets.
