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: $0.0335 / $0.083 · Relace (relace/fp4)
Unpinned range: input $0.0335–$0.1875, output $0.083–$0.625 across 41 endpoints of 36 providers (listing shows $0.15 / $0.50).
Price moves of 20% or more since the reading of 8 Nov 2026:
- OpenInference (open-inference/fp4): $0.06 / $0.24 → $0.06 / $0.30 (input 0%, output +25%).
- PrimeIntellect (primeintellect): $0.15 / $0.50 → $0.105 / $0.50 (input −30%, output 0%).
Observed unpinned cost: 126 short requests sent without a pinned provider on 25 Oct 2026 – 9 Nov 2026 (14 dates), in each routing mode. Charged is the sum of the OpenRouter generation receipts for these requests; the listing price column is the price of the same input and output tokens at the listing price of that date.

Routing modes as documented by OpenRouter (OpenRouter provider routing, read 25 Oct 2026): the default request has no provider field; :floor and :nitro are suffixes of the model name. Served by names the endpoint that answered, by the provider name and endpoint tag of the receipt. Each request asks for one short line with an answer cap of 32 tokens. The counts are for these requests on these dates only.
Models with the widest provider price spread on OpenRouter
Request fragment that pins Relace (relace/fp4):
{"provider": {"order": ["relace/fp4"], "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).
