AI 导读
SemiAnalysis 检测到 Anthropic 正在对部分账户 A/B 测试 Claude Max 用量限额：5 小时窗口用量增加约 20%，但每周用量减少约 20%，订阅价格不变。作者的评论是同价下重度用户总可用量变少，图示对比两个 Max 20x 账户，B 账户 5 小时窗口高 19%，每周额度低 20%。
推荐理由
原文引述 SemiAnalysis 的检测数据，说明 Anthropic 正在部分账户上测试 Claude Max 限额结构调整，对重度用户的总用量影响可直接参考。

.@AnthropicAI , you were on such a good roll! A/B testing 20% less weekly usage.
SemiAnalysis says Anthropic is now A/B testing Claude Max limits: roughly 20% more usage per 5-hour window, but 20% less per week for some accounts. tl;dr Same subscription price, less total usage for heavy users.
🚨🚨ALERT: ANTHROPIC IS A/B TESTING USAGE LIMITS Many users on X are reporting LOWER usage limits right now. THEY ARE NOT WRONG. We detected an A/B test going on that DECREASES your monthly API-value by ~20% while INCREASING your 5h usage limits by ~20%. This only affects SOME accounts. (1/2)🧵在 X 查看被引用的帖子
