DeepSeek V4 Pro runs $0.66 per million input tokens and $1.98 per million output at off-peak rates, with V4 Flash at $0.22 and $0.66. These replace V3 and DeepSeek Reasoner, which are no longer on the pricing page.
DeepSeek is the only major provider that bills on a clock. Peak hours are 01:00 to 04:00 and 06:00 to 10:00 UTC, Monday through Friday, and the rate doubles during those windows. For interactive traffic you cannot control when requests arrive, so budget at the peak rate for the share of your users who fall in those hours. For batch work you often can control it, and shifting a nightly job outside the peak windows halves its cost for the price of a cron change.

- Cost-sensitive high-volume workloads where a 2x swing is worth scheduling around
