METR 评估纳入 Anthropic 未发布模型，AI 进步加速估算升至 1.9 倍
Why we picked it
METR 拿到 Anthropic 内部未发布模型的数据，算出 1.9 倍加速率，比 Haiku 5.5 报的 1.7 倍还高，看看这些闭门模型到底多强。
独立评估机构 METR 在 AI 进步速度评估中纳入了 Anthropic 尚未发布的内部模型。这些新模型的基准数据将 METR 的加速率估算从 1.7 倍推高到 1.9 倍，此前 Anthropic 的 Haiku 5.5 系统卡报告的是 1.7 倍。METR 图表中最新的模型标注为 Model 4，2026 年 10 月已在 Anthropic 内部可用。

Anthropic has unreleased models that were included in an independent assessment of AI progress.
METR says benchmark data from those newer internal models pushed its estimated acceleration rate to 1.9x. Anthropic’s Haiku 5.5 system card had reported 1.7x.
The newest model in METR’s chart is labeled “Model 4” and was available internally in October 2026.
