  "content": "Anthropic's private, unredacted version of the August 2026 Risk Report contained figures and qualifications that the public version softened or left out: leading-indicator figures implying a speedup of about 1.97 were described publicly as \"less than a factor of 2\"; the private text called it plausible that AI-attributable speedup exceeded 2x, while the public text implied fair confidence it did not; and the public text omitted the private expectation that later Model 2 snapshots would score higher on the capability index, which they then did. A public report that states the evidence for acceleration more weakly than its authors' own contemporaneous assessment understates that acceleration.",

{
  "content": "The public report said AI R&D at Anthropic was \"significantly faster\" than without AI, described \"meaningful acceleration\" and \"early signs of potential acceleration\", said it was \"uncertain and measurement is difficult\", gave Model 2's score \"large error bars\", and lowered its confidence because its evaluations had saturated. A reader was therefore told that acceleration was substantial and near the threshold, and the wording differences from the private version are within the range of ordinary summarizing, so the public report did not understate the acceleration.",
