Find XO: KVBoost: Reducing LLM First Token Delay by 5–48× via KV Cache Reuse, Works Without GPU (pythongiant.github.io)

- The open-source KVBoost was posted on Hacker News. - It splits input into chunks, hashes them, and reuses the KV cache directly when the same chunk reoccurs. - It reduced time to first token by 5–48 times and runs on top of HuggingFace generate() without requiring infrastructure changes. - Before adopting it, we need to check how often the same context actually repeats in our requests to make these numbers meaningful.
