One dimension worth adding to the vLLM vs SGLang comparison is prefix caching behavior under variable-length system prompts. SGLang's RadixAttention handles shared-prefix batching more efficiently when your system prompts are stable across requests, which is the common pattern in agent pipelines. For workloads with highly dynamic prefixes, vLLM's PagedAttention still wins on memory fragmentation.
