DeepSeek V4 Flash tops China office Agent model calls

The rapid adoption of DeepSeek V4 Flash signals a decisive shift in China's enterprise AI landscape, where cost-efficient, task-specific models are outpacing generalists in office automation. The 75% share when including the visual variant underscores that multimodal capabilities are becoming a default, not a premium add-on. The geographic spread, with nearly two-thirds of users outside top-tier cities, suggests demand is broadening beyond coastal tech hubs, which could pressure competitors to localize and price aggressively. The open question is whether this dominance holds as rival models iterate, or if DeepSeek's lead is a first-mover advantage in a still-fragmenting market.
