[DeepSeek V4 Flash So Popular It Overloaded Servers, Official Suggests Using Alternatives] According to monitoring by 动察 Beating, the official release of DeepSeek V4 Flash quickly caused a surge in demand. The official API at one point returned a 503 error, indicating the service was too busy, and suggested users temporarily switch to other large model API providers. However, switching to third-party providers may not be as cost-effective. DeepSeek's official cache hit price is 0.02 yuan per million tokens, while Alibaba Cloud's BaiLian, Tencent Cloud, and ByteDance's Volcano Ark charge 0.2 yuan—10 times more expensive. Agents frequently read code and context, with cached tokens often accounting for the majority. Switching to platforms with higher cache hit prices would significantly increase actual costs.
