Props to them. That makes DeepSeek v4 Pro extremely cheap compared to others, even in the same category. Look at these prices per million outputs tokens:

DeepSeek V4 Pro: $0.87

Qwen 3.7 Max: $7.50

Grok 4.3: $2.50

GLM 1.5: $3.08

Opus 4.7: $25.00

GPT-5.5: $30.00

It's actually even cheaper when you look at the cache read costs. Those costs can dominate in agent workflows and DeepSeek's cost for cache reads is insanely low comparatively. At $.003626/M tokens, the cheapest other thing on your list is >$.2/M tokens. That's on the scale of 100x cheaper.

And they don't make the model worse once you have a subscription!

It doesn't matter how good Opus is if 2 months into your subscription they make it worse than GPT 3 to save money.
