Part of the explanation for why so few users will need to verify their age is that Discord already uses an internal "age determination" system that looks at "how long your account has existed, whether you have a payment method on file, what types of servers you're in, and general patterns of account activity."
GLU/SwiGLU 在实际中是门控形式（two linear branches），是向量上的逐元素操作；为了在一维上可视化，我用简化的标量形式来画图 —— 把两条分支都用相同的输入值（即把 a=x, b=x），因此 GLU(x)=x∗sigmoid(x) SwiGLU(x)=x∗SiLU(x) 。这能直观展示门控机制的形状差异。

In addition to the groups behind the celeb bait ads, Meta says that it's upgraded its ability to detect scam ads that use cloaking, which has at times hindered its internal review systems. The company also sued a Vietnam-based advertiser it says used scam ads to hawk "deeply discounted items from well-known brands," including Longchamp.
