Why on earth would you use openrouter for this? The cache discount for deepseek is the highest by far, it is the cache that makes the official API so cheap, even after the recent price rise.

I didn't know about this limitation from openrouter, and I thought plenty of users were using it to quickly switch as needed without incurring such a penalty. Why does there seem to be so many users then? Are some folks just fine paying multiples of what they could?
