Could you build this?
Partial A pure-Python educational walkthrough of prefix caching, chunk keys, and eviction is vibe-codeable. Faithful GPU tensor handling and vLLM integration require ML systems expertise.
What it would actually take: The pure-Python layers (hashing token chunks, storage backends, LRU or similar eviction) are straightforward. A real version needs PyTorch GPU memory management, correct KV tensor layout matching the model, and integration with vLLM's cache-manager internals, which needs inference-systems knowledge.
