Of course though they are not necessarily a viable solution for companies with security requirements etc. given it is just a single person project, but they still serve as a proof it can be done.

Deepseek's api platform for V4 Pro is the only example of this, and Deepseek V4 Flash is cheaper (usually) than from Deepseek itself on openrouter via DeepInfra.

Deepseek shot themselves in the foot because they never intended to serve V4 Pro for .80c mm ouput, that was a promotional price that was meant to expire (and still might). They intended for v4 to cost $4.00 per million but Western inference providers drove down the price because they can operate at negative margins to try and push competition out. I can assure you they are losing a ton of money @ ~80cents.

My point is, its Western inference providers that are establishing the floor price of inference. They are willing to operate at a loss in order to put their competition out of business. Chinese providers are typically at or above the prices set by American/western providers if you go looking on the Chinese internet. You aren't going to get deals from China for inference except through this one instance with Deepseek v4 Pro which wasn't even supposed to be permanent pricing.
