In large language model inference scenarios, the performance and flexibility of KVCache caching systems directly impact overall service efficiency. LMCache, as a high-performance large model caching framework, provides developers with rich extension capabilities through its modular backend design. This article will start with LMCache backend’s extension mechanism, using the officially provided lmc_external_log_backend as an example,…

TL;DR: 🚀 CacheGen lets you store KV caches on disk or AWS S3 and load them way faster than recomputing! It compresses your KV cache up to 3× smaller than quantization so that you can load your KV cache blazingly fast while keeping response quality high. Stop wasting compute — use CacheGen to fully utilize…
