Claude Sonnet 4.5 endpoint guide
5 of 8 Claude Sonnet 4.5 endpoints currently have the published data required for this ranking. Anthropic leads at 40.5 tok/s via anthropic/2. The table keeps unranked routes visible so missing measurements do not look like missing provider availability.
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.
Anthropic currently ranks second at 36.0 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.
Claude Sonnet 4.5 has 8 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.
