The DeepSeek API open platform will optimize its peak-valley pricing rules starting from 00:00 on August 23, 2026. After the adjustment, the entire weekend (Saturday and Sunday) will be billed at the unified off-peak rate. Charges incurred before the new rules take effect will still be settled according to the original standards. Previously, the platform adopted peak-valley pricing, with peak-hour prices being twice those of off-peak hours. Peak hours were from 9:00-12:00 and 14:00-18:00 Beijing Time.
