Know when DeepSeek is half price.
DeepSeek prices the same tokens differently depending on when a request runs. This page turns that schedule into a live rate board: what is active now, what comes next, and the cost per million tokens.

Control the cost
Cheap tokens are not a system.
We build AI workflows with human review, guardrails, and a cost model you can see. If your AI work needs a real operating layer, start here.
Pricing is read from DeepSeek's published model table. Image inputs follow its Vision billing rules, and the concurrency values come from its rate-limit documentation. DeepSeek can change prices or limits at any time, so confirm the final number in your own account before committing to a budget.
