Bits Per Weight
解决什么问题What problem it solves
量化档位的数值表示：平均每个权重占几个比特。The numeric form of a quantisation level: how many bits each weight averages.
这是什么What it is
衡量量化程度的指标。本站按 bpw 分成五档：极限压缩、长上下文优先、平衡档、保守档、近似无损。
数值越低，模型体积越小。
A measure of how aggressively a model is quantised. This site groups them into five tiers: extreme compression, long context first, balanced, conservative and near-lossless.
Lower numbers mean a smaller model.
为什么需要知道Why it matters
它把「Q4、Q8、Q3」这些各家不同的叫法统一成可比较的数字。这是选型时最实用的标尺。It unifies vendor-specific names like Q4, Q8 and Q3 into one comparable number — the most practical yardstick when choosing.
