DeepSeek has unveiled its latest API pricing policy, introducing peak-valley pricing adjustments: weekends that have been adjusted to workdays, along with Chinese national holidays, will now be subject to off-peak rates throughout the entire day. According to the 2026 holiday calendar, the Mid-Autumn Festival is scheduled from September 25th to 27th, while National Day falls from October 1st to 7th, with September 20th and October 10th designated as workdays. Since August 17th, DeepSeek has been implementing peak-valley pricing, and on August 23rd, it further refined its billing rules to offer all-day off-peak rates on Saturdays and Sundays. In addition, DeepSeek has also disclosed fundamental details, including the features, input/output pricing structures for various time slots, and concurrency limits for its two models, deepseek-flash and deepseek-v4-pro.
