Alongside the Harness release, DeepSeek shipped V4-Pro-0813 and announced across-the-board API price increases of 50% to more than 1,100% depending on model, token type, and time of day, effective 16:00 UTC on August 16, 2026. V4-Pro cache-miss input goes from $0.435 to $1.32 per million tokens at peak, with peak windows defined as 01:00–04:00 and 06:00–10:00 UTC and off-peak set at half the peak rate. This ends DeepSeek's role as the reflexive cheap-frontier default — anyone with V4 in a production loop needs to re-price before Sunday.
