[NeurIPS'25] The official code implementation for paper "R2R: Efficiently Navigating Divergent Reasoning Paths with Small-Large Model Token Routing"

LLMRouter: An Open-Source Library for LLM Routing

Efficient LLM query routing via multi-sampling. BEST-Route selects both model and number of responses based on query difficulty, cutting costs by up to 60% with <1% performance drop. From the paper:https://arxiv.org/abs/2506.22716

RouterArena: An open framework for evaluating LLM routers with standardized datasets, metrics, an automated framework, and a live leaderboard.

Per-step LLM routing benchmark with 970 static labels, live SWE-bench evaluation, an open data pipeline, and a public leaderboard.

A framework for serving and evaluating LLM routers - save LLM costs without compromising quality

A tiny ~10K-parameter LLM router that learns which open-source model (deepseek-v4-pro / glm-5p2 / kimi-k2p6 via Fireworks) should answer each question and in what role, trained by evolution (sep-CMA-ES).
