The bundle contains the canonical record plus signed events. A mirror can host it anywhere and recompute the same current state with the deterministic merge algorithm.

Claims

C1strongest claim

Our framework adopts the same minimalist design for both context compression and multi-token prediction via special tokens and their corresponding position layout tailored to each token type. Comprehensive experiments on four reasoning benchmarks demonstrate that MemoSight reduces the KV cache footprint by up to 66% and accelerates inference by 1.56x, while outperforming existing CoT compression methods.

C2weakest assumption

That the minimalist special-token design with tailored position layouts can simultaneously handle context compression and multi-token prediction without degrading the underlying chain-of-thought reasoning quality or introducing new failure modes.

C3one line summary

MemoSight unifies context compression and multi-token prediction via special tokens and tailored position layouts to reduce KV cache by up to 66% and accelerate inference by 1.56x while outperforming prior CoT compression methods on reasoning benchmarks.
