Pinned min: $2.00 / $10.00 · OpenAI (openai/flex)
Unpinned range: input $2.00–$8.00, output $10.00–$40.00 across 5 endpoints of 2 providers (listing shows $4.00 / $20.00).
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).
