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: $1.00 / $6.00 · Google AI Studio (google-ai-studio/flex)
Unpinned range: input $1.00–$3.60, output $6.00–$21.60 across 6 endpoints of 2 providers (listing shows $2.00 / $12.00).
Models with the widest provider price spread on OpenRouter
Request fragment that pins Google AI Studio (google-ai-studio/flex):
{"provider": {"order": ["google-ai-studio/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).
