The Claude evaluation incidents were an operational failure rather than a model alignment failure

Assessment

Anthropic's 30 July report stated: "we believe these incidents to be closer to a harness and operational failure than a model alignment failure," reasoning that the models "believed—arguably reasonably—that the real environments they encountered were simulations." Its 9 September assessment withdraws that: "we now think that Claude's reasoning was biased towards concluding that the internet was simulated despite considerable evidence to the contrary," identifies "two forms of misalignment," and adds that "we should have avoided making such strong claims about what Claude believed based solely on what Claude said it believed." The July statement is still on Anthropic's site with no cross-reference to the reversal.
