DeepSeek V3.1 Terminus endpoint guide
5 of 5 DeepSeek V3.1 Terminus endpoints currently have the published data required for this ranking. StreamLake leads at 18.68 s via streamlake. 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.
NovitaAI currently ranks second at 19.47 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.
DeepSeek V3.1 Terminus has 5 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.
