OpenRouter sends a call without a pinned provider to one of these endpoints, and each endpoint has its own price. Prices are USD per 1M tokens, input / output.

Pinned min: $0.50 / $1.50 · Mistral (mistral/zdr)

Unpinned range: input $0.50–$0.55, output $1.50–$1.65 across 2 endpoints of 1 provider (listing shows $0.50 / $1.50).

Models with the widest provider price spread on OpenRouter

{"provider": {"order": ["mistral/zdr"], "allow_fallbacks": false}}

With fallbacks turned off, OpenRouter does not move the call to another provider. A full endpoint tag pins that endpoint; the provider name alone covers all of its endpoints (OpenRouter provider routing).

• Hidden reasoning tokens are billed as output, at the output price, even though they are not part of the answer.
