Deterministic Inference across Tensor Parallel Sizes That Eliminates Training-Inference Mismatch

ICML 2026poster

Deterministic inference is increasingly critical for large language model (LLM) applications such as LLM-as-a-judge evaluation, multi-agent systems, and Reinforcement Learning (RL). However, existing LLM serving frameworks exhibit non-deterministic behavior: identical inputs can yield different outp…

RouterArena: An Open Platform for Comprehensive Comparison of LLM Routers

ICLR 2026poster

Today's LLM ecosystem comprises a wide spectrum of models that differ in size, capability, and cost. No single model is optimal for all scenarios; hence, LLM routers have become essential for selecting the most appropriate model under varying circumstances. However, the rapid emergence of various ro…
