DeepSeek Emails API Users Warning of a 'Significant' Price Increase — Its Second Pricing Change in Under a Month
DeepSeek notified API customers on August 6, 2026 that overall pricing will rise substantially, citing demand that exceeded platform capacity, frequent instability, and server costs that make loss-leader pricing unsustainable; the specific schedule is still pending official notice. DeepSeek-V4-Flash currently runs $0.14/M input and $0.28/M output — the floor that anchored the whole cheap-inference market. The notice says continued use after the adjustment constitutes acceptance and offers refunds to those who cancel, and it follows the peak/off-peak rate split introduced in mid-July, so anyone with a DeepSeek-priced cost model should re-run it now.
