Claude Opus 4.5 endpoint guide

How to interpret the Most Reliable Claude Opus 4.5 Inference Providers

3 of 6 Claude Opus 4.5 endpoints currently have the published data required for this ranking. Amazon Bedrock leads at 99.92% via amazon-bedrock. The table keeps unranked routes visible so missing measurements do not look like missing provider availability.

How recent uptime is ranked

The reliability ranking uses the published 30-minute endpoint uptime measurement. This short operational window can reveal current instability, but it is not a service-level agreement or a substitute for longer-term availability monitoring.

Compare Amazon Bedrock with the next option

Anthropic currently ranks second at 99.68%. 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

Claude Opus 4.5 has 6 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.
