“unknown” means the figure has not been published, or we have not verified it yet — never that the answer is no. “not published” under the weights licence means this model is not offered with downloadable weights. The price band is ours: it bands the blended price (three parts input to one part output) as budget (≤ $0.50), standard (≤ $3), premium (≤ $12) or flagship.

These figures come from OpenRouter's listing, not from the model maker's own price sheet. Treat them as the cost of routing through OpenRouter, not as an official tariff.

Lifecycle

OpenRouter has not announced a deprecation or shutdown date for this model. That is a statement about what has been published, not a guarantee — providers typically announce a shutdown months ahead, and this page updates when they do.

1. Released unknown
2. Deprecated not announced
3. Retired not announced
