DeepSeek Hikes V4 API Prices Up to 1100%, Introduces Peak/Off-Peak Pricing
DeepSeek's new API pricing took effect August 17 at 16:00 UTC, raising V4 series model prices by roughly 50% to over 1100% depending on model and time slot, and introducing peak/off-peak pricing for the first time. The move marks a clear departure from DeepSeek's long-standing ultra-low-price strategy.
Confirmed
- Effective August 17 at 16:00 UTC, confirmed by APPSO and Zhidongxi; peak hours are 9:00–12:00 and 14:00–18:00 at full price, with the remaining 17 off-peak hours uniformly at 50% off.
- V4-Flash peak output pricing rose from $0.28 to $1.32 per million tokens, roughly 4.7x.
- V4-Pro peak input rose from 3 to 9 yuan and output from 6 to 27 yuan, with cached-input pricing also adjusted.
- DeepSeek also launched V4 Pro, priced up to 14x higher than V4 Flash, creating a tiered lineup for different workloads and performance needs.
Why it matters
- Commentators such as Emmanuel Vivier noted that DeepSeek's low pricing was its core selling point; the hike signals a strategy shift that could significantly raise costs for apps built on its API.
- The peak/off-peak scheme, likened by Zhidongxi to utility time-of-use pricing, encourages load shifting and reflects peak compute supply pressure, a notable case of fine-grained pricing among Chinese LLM vendors.
