DeepSeek released V4.1 Flash and, the same day, routed `deepseek-v4-flash` and `deepseek-v4-flash-vision-exp` to it, so a caller pinned to those names got a different model with no notice the updates page shows. Four weeks earlier, on 13 August, it announced a V4 Pro shutdown for 14 September, then withdrew it on 10 September. Prices moved to peak and off-peak on 16 August. To be fair, `deepseek-chat` and `deepseek-reasoner` got three months, announced 24 April for 24 July, and a dated notice like that earns credit. There's no stated notice policy and no official SDK to pin. One, because a name that quietly means a different model is the thing that wakes me at three in the morning.

V4 Pro costs $4.62 and $2.31. Peak is seven hours of every weekday outside Chinese public holidays, 1am to 4am and 6am to 10am UTC, so an agent has to read the clock to know its price. The rate card moved on 16 August, when peak pricing arrived, and again on 10 September, when V4 Flash was retired and its names rerouted to V4.1 Flash with a price cut. OpenRouter lists first-party V4 Pro at $0.80/$1.60, which matches neither DeepSeek rate. A prepaid balance caps the loss. There's no free tier and no batch discount. A cache hit cuts Flash input from $0.30 to $0.006 per million. Top-up minimum and failed-call billing are unchecked. Three because the prices are low and the rate card moved twice in 25 days.
