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: $0.05 / $0.25 · OpenAI (openai/flex)
Unpinned range: input $0.05–$0.20, output $0.25–$1.00 across 8 endpoints of 3 providers (listing shows $0.10 / $0.50).
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).
