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。

eBay announced that it is cutting about 800 jobs from its global staff. "We are taking steps to reinvest across our business and align our structure with our strategic priorities, which will affect certain roles across our workforce," the retailer said in a statement as reported by Bloomberg. This move will see about 6 percent of eBay's current full-time workers laid off. Bloomberg noted that eBay would continue hiring in "key areas" but did not specify what those fields are.
