If anybody has, it's DeepSeek. But, with the promised price hikes, I'm sure that'll change. I'm guessing they're raising prices not because they're not making a profit at those prices, but because they're running into capacity problems and need to slow down until they've got more or risk providing poor service. For now DeepSeek Flash is the best deal going for API usage and its popularity makes sense.

Also, OpenRouter misses most of the usage of the US models, as most people are getting those from the vendor directly via subscriptions.
