Isn't this a bad deal? Or is there an error in my math?

For $40, I'd get 20 tok/s * 2.6M seconds per month = 52M tokens of DeepSeek v3.2 per month if I run it 24/7, which is not realistic for most workloads.

On OpenRouter [1], $40 buys 105M tokens from the same model, which is more than 52M tokens, and I can freely choose when to use them.

20 tok/s is an average. It can be more, it can be less. If you are running off-peak I'm sure you'd get some crazy number.
