claude code 送了 100 美元

\(99.95 Current balance· Auto-reload Off US\)99.94 Promotional credit Expires September 19, 2026

看着是到 9.19 过期，超限后看着会使用这个 100 美元，我开了 Usage credits 这个开关，刚试了下 5h 超限会用这个 100 美元里的额度，目前看用了$0.05

Your limits are temporarily boosted. Your weekly Claude Code limit is 50% higher(opens in new tab) through August 19, and your Cowork limit is 100% higher(opens in new tab) through August 5. When each promotion ends, limits return to your plan’s standard amounts.

8.19 前 周限增加 50%？

这个是全部人都有还是部分随机？ K3 gpt 给压力了？
