Anthropic 内部报告：Mythos Preview 加速提升 4 倍
精选理由
Anthropic 自己披露的 4 倍加速数据，还卡在 RSP 阈值之下，但那是 Mythos Preview 时代的事了。
Andrew Curran 指出，Anthropic 在 2026 年 8 月风险报告中自报的内部加速提升为 4 倍。该数值仍低于 Anthropic 负责任扩展政策中 Dramatic Acceleration 的阈值。报告针对的是 Mythos Preview 版本，目前模型已迭代多代。

A 4× internal uplift is consistent with what Anthropic self-reported in their August 2026 Risk Report. This is still below Anthropic's Responsible Scaling Policy threshold for Dramatic Acceleration.
This report was for Mythos Preview. They are many generations beyond this now. https://t.co/nno9lg742T
