DeepSeek's new prices take effect 16 August. Input and output rise about 3x for V4 Flash and 3x and 4.6x for V4 Pro, and V4 Pro cache rises from $0.003625 to $0.044 per million tokens (about 12x). If your business runs AI tools or chatbots on DeepSeek's API, recheck your monthly cost estimates and cache usage. DeepSeek still offers a 50% discount outside peak hours (peak is 08:00-11:00 and 13:00-17:00 Thailand time), so scheduling non-urgent jobs off-peak can offset the increase.
