The developer of OmnisRouter, a tool designed to route LLM requests to the most cost-effective model, has shared benchmark results that place their router near the bottom. Despite initial bugs in the testing setup, the corrected OmnisRouter achieved 72.7% accuracy at a cost of $3.71 per thousand queries on RouterArena. This performance ranks it 16th out of 18 routers, primarily due to its high cost compared to other routers that utilize cheaper, open-source models. AI
