# DeepSeek V4 Model Launches Mid-July With Expanded Context and Peak-Hour Pricing

> DeepSeek is formally launching V4 in mid-July, extending the preview it showed in April into a full release. The model pushes its context window to one million tokens and claims stronger reasoning, agentic and coding performance, arriving in two flavors: deepseek-v4-flash for latency-sensitive work and deepseek-v4-pro for heavier reasoning. The more interesting wrinkle is the business model. DeepSeek is introducing peak-hour pricing, so calls made during busy local windows, roughly 9am to noon and 2pm to 6pm, cost twice the off-peak rate, while off-peak prices stay where they were. It is a surge-pricing approach borrowed from ride-hailing and cloud computing, and a candid acknowledgment that inference capacity is a scarce, time-sensitive resource. For a Chinese lab operating under US export controls, squeezing more value out of constrained hardware is not a gimmick, it is strategy. Peak-hour pricing nudges non-urgent workloads into off hours and smooths demand, which matters a great deal when you cannot simply buy your way to more chips. Expect other providers to watch closely.
