Validating Hybrid-State Cache Recovery for GLM-5.3-Flash with vLLM and LMCache

A new arXiv paper investigates whether an external cache transfer that appears successful can still leave a hybrid language model resuming from an inconsistent internal state. The authors test the full 45-layer GLM-5.3-Flash model using the RedHatAI NVFP4 quantized checkpoint together with vLLM and LMCache under a four-way configuration. The work focuses on validating cache recovery correctness rather than raw throughput.

arXiv Study Tests Shared KV Cache Across Two 27B vLLM Replicas

Researchers examined what happens when two single-GPU 27B vLLM inference replicas share a 256 GiB host-memory cache pool (LMCache), aiming to skip repeated prefill work as requests move between replicas. The paper reports both correctness problems in transferring cached state and performance limits tied to lost prefix locality. The authors argue that shared caching only pays off when state handoff is reliable and locality loss stays small.
