TriRoute paper introduces unified controller for adaptive LLM inference

Researchers have introduced TriRoute, a novel system designed to optimize language model inference costs by jointly managing attention resolution, expert selection, and KV-cache quantization. This unified controller adapts its policy for each token at every layer, determining attention mode, FFN expert usage, and KV-cache bit-width. TriRoute demonstrates Pareto dominance over independent optimization methods, significantly improving performance on rare entities, code, and arithmetic while maintaining robustness. AI

IMPACT Optimizes LLM inference by jointly adapting attention, experts, and KV-cache, improving efficiency and robustness on complex tasks.
