[DeepSeek API Billing Adjustment: Weekend Charges Unified at Off-Peak Rates] Odaily Planet Daily News: According to 'Sci-Tech Innovation Board Daily,' the DeepSeek API open platform will optimize its peak and off-peak billing rules starting from 00:00 on Sunday, August 23, 2026. After the adjustment, weekends (Saturday and Sunday) will no longer differentiate between peak and off-peak periods, and charges will be uniformly applied at off-peak rates. Fees incurred before the new rules take effect will still be settled according to the original billing standards. Previously, DeepSeek announced an API pricing adjustment, adopting a peak and off-peak pricing model, where peak period rates were twice those of off-peak periods. Under this model, the maximum price for one million tokens output during peak periods for deepseek-v4-pro reached 27 RMB. Peak periods were defined as 9:00-12:00 and 14:00-18:00 Beijing time (all other times were considered off-peak).
