一条条生成是零售价，一批批生成才是批发价。电商上新 50 个 SKU、客服要 30 条标准回复、投放要 40 个标题——这类活按批算：免费试 5 条；充值 $2=200 点，50 条一批只扣 20 点，点数永久有效。
Generating one at a time is retail; real workloads are wholesale. 50 SKU descriptions, 30 support replies, 40 title variants — batch work priced like batch work: 5 free to try; $2 = 200 credits, a 50-piece batch costs 20, credits never expire.
