[Tencent Mixed Yuan Team Takes a Week Off After Delivering Hy4] Beating AI Newsflash: The Tencent Mixed Yuan team has reportedly taken a one-week break following the release of the Hy4 preview. The team’s workspace, which usually has staff working long-term, was almost empty this week. This break is related to the release of the latest version of Mixed Yuan. On August 28, Tencent open-sourced the Hy4 preview, which is currently the largest open-source model version of Mixed Yuan, featuring a total of 770B parameters, 49B active parameters, and a context length exceeding 1M. Prior to the release of Hy4 preview, the team had been pushing the project forward intensively for several months. After the version went live and received internal approval, the company arranged for the team to take a phased break. In the context of accelerating competition in large models, long-term high-intensity R&D by model teams has become the industry norm. Many teams immediately enter the next round of development after releasing a model, making this kind of concentrated rest after achieving a milestone relatively rare. [Original Link]
