Blockwise Approximate KV Cache Technique

A Blockwise Approximate KV Cache Technique is an approximate block-based model inference optimization technique that reuses key-value computations for stable sequence blocks while recomputing only for changing regions in blockwise approximate KV cache inference (enabling efficient caching in diffusion models).

  • ...
• Counter-Examples:
  • Full KV Cache, which stores all computations without block approximation.
  • No-Cache Recomputation, which recalculates everything rather than selective reuse.
  • Token-Level Cache, which caches individually rather than in block structures.
