DeepSeek has raised API pricing significantly following the V4 Pro launch: input/output costs increased 3–4.6x, while cache pricing jumped 12x (from $0.003625 to $0.044 per million tokens). The increases take effect August 16, though off-peak discounts (50% off outside 8–11 AM and 1–5 PM Thailand time) provide some relief. This ends DeepSeek's aggressive pricing strategy and signals the market transition from disruption to profitability.
