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: input $0.153 · Wafer (wafer/fast); output $9.3388 · Relace (relace/fp4)

Unpinned range: input $0.153–$4.50, output $9.3388–$22.50 across 30 endpoints of 21 providers (listing shows $2.2335 / $15.00).

No endpoint in this reading sells at the listing price.

Price moves of 20% or more since the reading of 8 Nov 2026:

  • Listing price $0.192 / $16.00 → $2.2335 / $15.00 (input +1063%, output −6%).
  • Io Net (io-net/fp4): $2.30 / $14.00 → $1.50 / $14.00 (input −35%, output 0%).

Observed unpinned cost: 117 short requests sent without a pinned provider on 28 Oct 2026 – 9 Nov 2026 (13 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 Wafer (wafer/fast):

{"provider": {"order": ["wafer/fast"], "allow_fallbacks": false}}

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).

  • Hidden reasoning tokens are billed as output, at the output price, even though they are not part of the answer.
  • Through OpenRouter, the request goes to the named provider; the price and speed can differ from the direct API.
