Smart LLM Routing Cuts Inference Costs by 65% While Maintaining 99.2% Accuracy
shensi · x · 2026-08-06
Merge published benchmark results for its Merge Gateway intelligent routing. Across 120 paired trials, the router achieved a 65% cost reduction—spending $2.87 compared to the flagship model's $8.17—while maintaining a 99.2% correctness rate versus the flagship's 100%.
The evaluation focused on two key dimensions:
- Routing Overhead: Measuring the latency added when the gateway acts purely as a call router.
- Intelligent Routing: Assessing cost savings and potential trade-offs in correctness and latency when dynamic routing is enabled.
