One-line takeaway
PACE is a post-hoc 4-bit quantizer for linear-attention recurrent states: it rounds only every few tokens with a small buffer in between and exploits column-clustered outliers via channel-aligned encoding, letting more sequences share an accelerator.
PACE 是线性注意力模型循环状态的训练后 4 比特量化：每隔几个 token 才取整一次并缓存其间的 token，再利用大值集中在少数列的规律按通道对齐编码，让同一加速器同时解码更多序列。
