## Summary

vLLM says its new blog covers engineering improvements, including metadata-only requests that avoid duplicate preprocessing and Mooncake/NIXL embedding transfers. The post also cites cross-encoder caching and EPD integration with vLLM Router, SMG, and llm-d for independent scaling of encoder and language-model instances.
