Step 3.7 Flash endpoint guide
4 of 4 Step 3.7 Flash endpoints currently have the published data required for this ranking. DeepInfra leads at 3.33 s via deepinfra. The table keeps unranked routes visible so missing measurements do not look like missing provider availability.
The fastest ranking estimates a 500-token answer by adding the recent median first-token wait to 500 divided by median output throughput. It represents an example complete response, not a guarantee for every prompt or request size.
Ambient currently ranks second at 5.77 s. Compare that gap with input and output price, response-start time, output speed, 30-minute uptime, context length, and the exact route before deciding whether first place is meaningful for your workload.
Step 3.7 Flash has 4 published provider options, and performance data is matched to each exact OpenRouter routing tag. Different quantization, context, regional deployment, or provider configuration can change price and behavior even when the underlying model name is identical.
