Recently, Tencent launched an AI search function on its social platform WeChat, which became unusable due to server overload less than a day into its grayscale testing. According to Tencent, the feature utilizes the Hunyuan large model for searches and integrates the DeepSeek-R1 model to provide deeper thinking services. However, despite the very small user count participating in the testing, the call volume was extraordinarily high, resulting in frequent prompts stating 'Service is busy, please try again later.' In this situation, Tencent had to quickly take action.
