CMU releases ServerBench, testing coding agents on LLM serving system design
Overview
Carnegie Mellon University introduces ServerBench, a benchmark that asks coding agents to design complete, specialized LLM serving systems and decide how many concurrent sessions to run.
Systems are scored on latency-qualified token value per GPU dollar.
In the paper's tests, Claude Sonnet 5.5 built a serving system for Gemma E4B that delivers 4.87 times the value per GPU dollar of the vLLM reference. Across 11 coding-agent models and three deployments, 22 of 33 runs produced a verified system, and 13 beat the strongest baseline.
