arXiv:2605.21312v1 Announce Type: cross Abstract: Modern LLM serving is no longer homogeneous or monolithic. Production systems now combine disaggregated execution, complex parallelism, runtime optimizations, and stateful workloads such as reasoning, agents, and RL rollouts. Simulation is attractive for exploring this growing design space, yet existing simulators lack the architectural completeness and decision-grade fidelity it demands. Their monolithic-replica abstractions are ill-suited to disaggregated serving, while average-case analytical proxies can distort SLA predictions and even reve
The increasing complexity of LLM serving architectures, including disaggregated execution and stateful workloads like AI agents, is driving the need for more sophisticated and accurate simulation tools to optimize performance and resource utilization.
Accurate LLM inference simulation is critical for predicting system performance, optimizing resource allocation, and ensuring reliable operation of complex AI systems, directly impacting the efficiency and scalability of AI development and deployment.
The development of 'Frontier' signifies a foundational improvement in LLM simulation capabilities, moving beyond monolithic abstractions to better model disaggregated and stateful AI workloads, leading to more informed design decisions.
