DeepSeek has launched the official version of DeepSeek V4 Pro and sharply lifted API fees, shifting toward profitability after winning users with prices roughly one-tenth of rivals' rates. Peak pricing is now CNY 9 per million input tokens and CNY 27 per million output tokens, with off-peak rates at half that level, while cache-hit pricing rose 12-fold to CNY 0.3. The company is building a revenue model ahead of a planned CNY 50 billion fundraising round and an initial public offering, after ranking first in global token processing volume from the 27th of last month through the 2nd of this month. Earlier channel monitoring showed Alibaba Cloud and Tencent Cloud matching the increase immediately, while other Chinese and overseas resellers lagged or kept cheaper flat rates, and coding tools absorbed the rise through lower quotas. The exact peak schedule remains unclear, with the new source describing 11 peak hours and earlier monitoring citing seven. Moonshot AI and ByteDance are also moving to paid billing, while U.S. rivals argue total cost depends on token-efficiency, not sticker price alone. Customer churn is still uncertain because DeepSeek has not published V4 Pro benchmarks.
