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: $15.00 / $90.00 · OpenAI (openai/flex)

Unpinned range: input $15.00–$30.00, output $90.00–$180.00 across 3 endpoints of 2 providers (listing shows $30.00 / $180.00).

Models with the widest provider price spread on OpenRouter

Request fragment that pins OpenAI (openai/flex):

{"provider": {"order": ["openai/flex"], "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).
