How much does DeepSeek V4 Pro cost?

DeepSeek V4 Pro starts at $0.522 per 1M input tokens through the API Stock API. You pay per use from a single prepaid balance — there is no subscription — and the final price scales with parameters such as resolution or duration.

DeepSeek V4 Pro was released on April 24, 2026. It is available through the API Stock API with the same key and prepaid balance as every other model.

How do I get an API key for DeepSeek V4 Pro?

Sign up for API Stock, top up your balance by any amount and create an API key in the dashboard — it takes a couple of minutes and needs no contract. The same key works with every model in the catalog, so there is no separate key to obtain for DeepSeek V4 Pro.
