OpenRouter providers who serves this model through OpenRouter, at what price

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: $0.15 / $0.60 · Mistral (mistral/zdr)

Unpinned range: input $0.15–$0.165, output $0.60–$0.66 across 3 endpoints of 1 provider (listing shows $0.15 / $0.60).

Models with the widest provider price spread on OpenRouter

Request fragment that pins Mistral (mistral/zdr):

{"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).
