DeepSeek officially announces a price reduction for the flash series models, with discounts of up to 60%.

DeepSeek Open Platform Announcement: Starting at 12:00 PM Beijing time on September 10, 2026, the pricing for the flash series will be adjusted as follows: the price per successful cache hit during off-peak hours will be 0.02 yuan, and the price per cache miss will be 1 yuan, while the output price will be 4 yuan; during peak hours, the prices will be twice that of the off-peak hours. Peak hours refer to Beijing time from Monday to Friday, 9:00 AM to 12:00 PM and 2:00 PM to 6:00 PM (the remaining times are considered off-peak). Compared to the old prices, this price cut is significant. For the deepseek-v4-flash and deepseek-v4-flash-vision-exp models, the prices for cache hit input, cache miss input, and output per million tokens are now 0.05 yuan, 1.5 yuan, and 4.5 yuan, respectively. As a result, the price reduction for cache hit input reaches 60%, the drop for cache miss input is about 33%, and the output has decreased by approximately 11%. It is worth noting that this is already the second price adjustment by DeepSeek in recent times. As early as August 23, the platform optimized the peak and trough billing rules, removing the distinction between peak and trough on Saturdays and Sundays, with a unified implementation of the off-peak price. Even earlier, on August 17, DeepSeek completed a round of peak and trough pricing adjustments for the V4 series, during which the peak prices were significantly raised.
