DeepSeek emailed customers that API prices will rise significantly, with no date given. Current prices are very low after a May cut (V4 Pro at $0.435 input / $0.87 output per million tokens), and cached input is priced at about a tenth of other providers. If your business uses DeepSeek's API for chatbots, document handling or agent-style workflows, review your AI costs now and budget for higher rates. Prepaid balances can be refunded on request. Note that DeepSeek's terms let it train on data even for paid API use, so avoid sending confidential customer data.
