Speculative KV coding: losslessly compressing KV cache by up to ~4×

38 kkm 2026-06-07 07:15:16 UTC fergusfinn.com Llama Share 5

Speculative KV coding is a lossless compression method for large language model (LLM) caches, using a predictor model to estimate the cache's values and an arithmetic coder to encode the differences. The method can achieve up to 8x compression on original bf16 caches and stacks multiplicatively with lossy quantization.

Whether one’s dealing with biology, economics, politics or a host of other fields, it’s common to encounter situations that can be modeled as involving two agents that repeatedly compete with each other. One imagines that at each step each agent can take one of a certain set of actions, and that then—in a classic game theory way—each agent (or “player”) gets a certain fixed “payoff” based on ...

A recent Linux kernel proposal to add "spawn templates" to optimize the fork() and exec() pattern has been rejected, but it may point to a new process-creation primitive in the future. The discussion highlights the need for a better process-creation mechanism, with some suggesting a native implementation of posix_spawn() and others proposing alternative approaches using existing system calls.

Arithmetic Without Numbers – How LLMs Do Math

A language model can perform arithmetic operations without explicit programming, but the question is whether it recalls a pattern, runs an algorithm, or merely produces a plausible next token. The project Rune found that a language model's internal state can supply operation and operand structure for arithmetic prompts, which can drive a calculator route under an opaque-prompt boundary.
