  "note": "The review sets passages of the public report beside passages of the private, unredacted version Anthropic shared, and shows three places where the public text is more confident than the private one: a leading-indicator speedup the private figures put at about 1.97 is described publicly as less than a factor of 2; the private report calls it plausible that AI-attributable speedup exceeds 2x while the public one implies more confidence; and the public report omits Anthropic's private expectation that later Model 2 snapshots would score higher on its capability index, which they did. The private quotations are partly redacted and the 1.97 figure is the reviewers' own calculation, so readers cannot check these numbers; Anthropic approved the published text and its co-founder said many of the conclusions match his own.",
