Inference-cost pressure produces both a serving paper and a prompt-stripping trend
A new method for compressing the key-value cache (the memory a model builds up as it generates text) targets the long chains of reasoning that make these models expensive to run, while developers manually cut their own token costs.
Reasoning models generate long chains of reasoning, and that verbosity accumulates a large key-value cache during decoding, which raises latency and limits throughput. A new paper, Kara, proposes sliding-window KV-cache compression tailored…

AI Inference Shifts to Consumer Devices
Over the next 3-6 months, smaller efficient architectures and inference-cost optimizations push capable AI off the cloud and onto laptops, phones, and mobile NPUs.
