Anthropic的Claude Fable 5（7月1日版）回归后在BridgeBench重测中表现大幅下滑：Debugging从86.2暴跌至25.9，Refactoring从73.6降至38.4，Hallucination从75.9滑落至61.7。原因是新安全护栏并非简单拒绝层，而是将标记请求路由至较弱的Opus 4.8，导致大量任务回退。Rohan Paul评论称这标志着普通人可能再也无法获得升级的前沿模型，如今只有“许可智能”。

Feels like an end of era, ordinary people will probably never again get upgraded frontier models.
Fable 5’s return shows how safety routing can downgrade a frontier model.
Now we only permissioned intelligence.
The cost of putting a gatekeeper inside intelligence.
To note, that safeguard is not a simple refusal layer; it is a classifier that sends flagged Fable 5 requests to Opus 4.8.
Fable 5 came back, but the old promise did not.
End of an era. ☹️
FABLE 5 CAME BACK NERFED. We re-ran the July 1st version of Claude Fable 5 on BridgeBench. The results are brutal: Debugging: 86.2 → 25.9 Refactoring: 73.6 → 38.4 Hallucination: 75.9 → 61.7 The new guardrails are kicking in on way too many tasks and falling back to Opus 4.8. This is not the model that got banned. Anthropic owes everyone an explanation.在 X 查看被引用的帖子
