CodeRouterBench - LLM Router (0-Shot): leaderboard
Model routing for coding tasks from Agent-as-a-Router (Zhou et al., 2026): the model reads each of the 2,919 in-distribution CodeRouterBench coding tasks and picks which of eight candidate LLMs should solve it, with no examples. Score is the average recorded task score in percent of the chosen models, where a missing result counts 0; higher is better.
Metric: Average task score (%) of the backend the model routes each task to, over the 2,919 in-distribution CodeRouterBench coding tasks (execution-graded or proxy scores of eight candidate LLMs, a missing result counting 0); the router picks one of the eight by name; zero-shot router prompt). Source: arxiv.org. Saturation forecast: Not forecast. 8 models tracked.
