DeepSeek V4 Flash is so popular that it's causing servers to crash. The official recommendation is for users to use another platform for now.

According to DynoBeat monitoring, after the official release of DeepSeek V4 Flash, it quickly experienced a surge in volume. The official API briefly returned a 503 error, indicating the service was overloaded, and advised users to temporarily switch to other large model API providers.

However, switching to a third party may not necessarily be cheaper. DeepSeek's official cache hit price is $0.02 per million tokens, while Alibaba Cloud, Tencent Cloud, and Volcano Ark under Byte all charge $0.2, which is 10 times more expensive.

The Agent will repeatedly read the code and context, with token caching often accounting for the vast majority. After moving to a platform with a higher cache hit price, the actual cost will increase significantly.
