I checked. OpenRouter provides their own. They use their actual cost, which is what they charge users, and their benchmarks results. Please, spend a few minutes to browse it. You'll notice that the likes of Luna is dominated by quite a few entries.

Subscriptions are actual costs to users. And Openrouter doesn't consider that. If you're talking API prices, those aren't actual costs to inference providers.

does not consider subscription subsidization
