The Physics of High-Fidelity Distributed Inference Platform Simulation

Production LLM inference platforms are distributed systems where routing policies, admission control, autoscaling, and engine-level scheduling all interact to determine latencies and throughput. How do you explore how different policies and configurations affect these KPIs before deploying to production? Testing a new routing policy or autoscaling threshold on live traffic risks cascading bugs across the fleet, while building separate test environments burns GPU-hours and still cannot predict interactions between cluster-level policies and engine-level batch dynamics.

Why Simulate Before You Scale

Deploying large language models in production is one of the most expensive infrastructure decisions an organization can make. A single high-end GPU costs upwards of $30,000, and a production cluster can run into millions per year. Yet most teams make their first scaling decisions based on rough estimates, vendor benchmarks, or — worst of all — trial and error on live hardware.

What if you could test your deployment plan before spending a dollar on GPUs?
