Low Risk, Shaky Evidence: An Outside Reviewer Grades Anthropic’s Safety Case

On October 20, the nonprofit METR published a review of the misalignment section of Anthropic’s August Risk Report, based on the internal, unredacted version. METR agrees that the risk from Anthropic’s current models is low, but mainly because the models aren’t yet capable enough, not because safeguards have been shown to work. It doubts Anthropic’s methods would reliably detect higher risk. In this episode What Anthropic’s Risk Report assessed, and the terms under which METR reviewed it Why a monitor flagged about 1% of a model’s actions in a real incident, versus about 50% when the model’s reasoning was hidden METR’s view that the summer incidents undercut parts of Anthropic’s argument, and its call to publish four withheld pieces of information An experiment showing Claude’s review of its maker’s safety case depends on how it’s asked Caveats: a “relatively lightweight” review based only on the report, by one evaluator Bottom line METR’s best guess is that misalignment risk is low today, mainly because of the models’ limited capabilities. Whether the gaps it identifies close before models become more capable is the question future reviews will need to answer.
