According to CoinMeta, Tencent's Hunyuan Hy4 was released and open-sourced on August 28th. Within just 3 days of its launch, it became overwhelmed due to a surge in usage requests. The WorkBuddy team urgently expanded the Hy4 Preview inference cluster and will dynamically increase resources based on usage. The total number of parameters is 77 billion, with 4.9 billion activated per inference, and the context capacity reaches 1M. On the day of release, it was simultaneously integrated with WorkBuddy, CodeBuddy, Yuanbao, and IMA, and is also available on WorkBuddy and CodeBuddy. The team stated that the total amount of high-end computing power and peak concurrency are still limited, so there may still be times when users need to wait in line. Temporary solutions include switching back to Hy3 or avoiding the evening peak hours. The free trial period for Hy3 has been extended until 23:59 on September 30th.
