Deepseek proper is the only provider offering Deepseek V4 Pro at such an insanely low price. All the other providers are like 5x.

If someone says they're using Deepseek, it's probably a safe bet that they're sending money to China. People choose an inferior model (Deepseek) because it's cheaper. Not many people are willing to use Deepseek but also pay the 5x price to have an American company run it for them.
