The Greenest Data Center Was Not the Fastest One
InFactPlanner compares energy, carbon, water, latency and utilization before an LLM-serving deployment is built.
Summary
InFactPlanner compares energy, carbon, water, latency and utilization before an LLM-serving deployment is built.
The trace-driven planning tool combines workload traces, hardware profiles, site capacity, power and water effectiveness, renewable generation and time-varying grid carbon. Its accounting reproduced reference inference-energy estimates within 10 percent, then explored hardware, location, renewable placement and routing scenarios. The case studies show sustainability-optimal choices can diverge from latency-optimal ones and depend on the local grid mix; the framework estimates alternatives rather than measuring a finished facility.
Why it matters
InFactPlanner compares energy, carbon, water, latency and utilization before an LLM-serving deployment is built.
