New algorithm optimizes LLM routing by learning user preferences online

By PulseAugur Editorial · [1 sources] ·

Researchers have developed a new algorithm for personalized LLM routing that learns user preferences online to minimize inference costs while maintaining response quality. The approach frames the problem as a constrained contextual bandit, balancing cost and reliability even with unknown user preferences. This framework is applicable to various online model selection scenarios requiring reliability guarantees. AI

IMPACT This research could lead to more efficient and cost-effective use of LLM resources by dynamically routing requests based on learned user needs and model capabilities.

    Chance-Constrained Personalized LLM Routing with Online Preference Learning

    arXiv:2610.22695v1 Announce Type: new Abstract: We study personalized LLM routing, where a router selects among heterogeneous models with different costs and capabilities. The router must minimize cumulative inference cost while ensuring reliable realized response quality, even t…
