Pricing Details
OpenAIOpenAI publishes NO rate for this model. It ships the weights (Apache 2.0) but sells no hosted inference for it, so the figure here is a third-party host's price, not OpenAI's, and it cannot be checked against an OpenAI page. Confirmed absent from OpenAI's own rate card on 2026-08-17. Open-weights models legitimately price differently on every host; treat this as one host's number.
