DeepSeek Emails API Users Warning of a 'Significant' Price Increase — Its Second Pricing Change in Under a Month
TechNode / Hacker News·high signal
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.
