GPT-5 endpoint guide

How to interpret the Highest Output-Speed GPT-5 Inference Providers

3 of 3 GPT-5 endpoints currently have the published data required for this ranking. OpenAI leads at 65.0 tok/s via openai/default. The table keeps unranked routes visible so missing measurements do not look like missing provider availability.

How generation throughput is ranked

The output-speed ranking compares recent median generated tokens per second. It favors routes that complete long generations quickly, while first-token latency remains a separate measure of how responsive the endpoint feels at the beginning.

Compare OpenAI with the next option

Azure currently ranks second at 52.0 tok/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.

Use the route, not only the provider name

GPT-5 has 3 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.
