How to choose a Claude Opus 4.8 (Fast) inference provider

Claude Opus 4.8 (Fast) is indexed here as a text model by Anthropic, with 1 provider endpoint from Anthropic. The comparison preserves each exact OpenRouter routing tag so pricing and performance observations can be connected to the route an application would actually request.

Match the endpoint to the workload

The model publishes a 1M-token context window. It accepts text, image, file input and returns text output. 10 distinct supported parameters appear across the listed routes. Confirm limits on the specific endpoint rather than assuming every host exposes the same configuration.

Compare the real request economics

Anthropic currently has the lowest estimated cost for the standard 1,000-input/500-output-token sample at $0.035. Input-heavy and output-heavy applications can produce a different result, so review both per-million-token prices in the endpoint table.

Balance response start and generation speed

Anthropic currently has the shortest estimated 500-token response at 7.38 seconds. Anthropic is the single endpoint closest to the current ideal cost/speed combination. Recent observations can change, so validate finalists with your own prompts.
