DeepSeek V4还能更省！新工具缓存命中率高达99.82%，2折稳定到手

Reasonix uses an append-only loop for DeepSeek V4 and reports a 99.82% cache hit rate in long coding sessions, cutting an example 400M-token bill from $61 to $12.

Why it matters: HKR-H/K/R all pass, but this is a third-party cost tool around DeepSeek V4, not a model launch or platform update. Concrete mechanism and billing numbers put it in the 72–77 featured band.
