Key Info

Adding :nitro to any model slug on OpenRouter routes the request to whichever provider is currently serving that model fastest.

Highlights

  • :nitro suffix selects the fastest provider for a given model in real time
  • Tested on DeepSeek V4.1 Flash, described as the most used coding model
  • Same prompt latency: 6.8s without :nitro vs 3.9s with it
  • Roughly a 43% latency reduction in this test
