What first-token latency measures
First-token latency measures how long users wait before an answer begins. The rank favors consistent results across several models, while the table shows the published response-start time for practical expectations.
LLM Providers: Weekly Latency Leaderboard & Benchmarks
The model-adjusted rating compares consistent first-token latency across exact-model comparisons, so one unusually strong model cannot dominate the result. A model-adjusted rating requires at least three exact models measured on another provider. Providers with only their own models remain visible using raw published catalog speed.

Weekly benchmark guide
How to use the LLM Providers: Weekly Latency Leaderboard & Benchmarks
26 providers currently have enough shared measurements for this weekly benchmark. ModelRun is currently first, with a published catalog median of 0.33 seconds. Review response time, response start, output speed, and coverage together before choosing a provider.
Why the weekly model set changes
This weekly view evaluates OpenRouter’s 15 currently popular models, so it reflects recent market demand rather than every model in each provider catalog.
Read the coverage before choosing
This page reviewed 40 candidate models and currently has shared comparison data for 26 providers. The Rating basis field distinguishes model-adjusted rows from providers positioned using only their own-model catalog measurements.
