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.

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.
