LLM KV cache prefixes are now understood to be fixed, not changed. Masking is used instead, which could lead to up to 65% faster AI responses.

πŸš€ Wow, groundbreaking insight: KV Cache is the new "memory hierarchy" of inference! πŸ€” Because, you know, we needed another reason to marvel at JavaScript's infinite wisdom in making web pages less user-friendly. πŸŽ‰ Thanks, Touchdown Labs, for this revelationβ€”my cache is now full of sarcasm.

KV Cache Is Becoming the Memory Hierarchy of Inference

A briefing on the inference memory hierarchy: prompt layout, host-side shared KV, distributed lookup, RDMA transfer, encoder reuse, and evidence discipline. Covers vLLM Γ— Mooncake, LMCache MP, LMCache CacheBlend, SGLang, NVIDIA Dynamo, and Modal cold starts.

Japanese brokerage Nomura raises SK Hynix target price to 4 million won, citing structural memory shortage driven by exponential KV cache demand in reasoning AI era, arguing semiconductor giants deserve TSMC-level valuations as growth stocks rather than cyclical plays amid supply-demand imbalance expected to persist for years.

How LLM Inference Works

When you enter a prompt into an LLM, the model converts your text into numbers, processes them, and returns a response one token at a time. In this article, we go through the journey of LLM inference and see how it works.

if you or someone you know has hit real crazy numbers on a single gpu setup with turboquant or any kv-cache compression scheme, point me. i will test it on my machines. if it delivers, i amplify you and your work, and ship the receipts publicly so the next builder does not have
