Synthesised from Anthropic's own disclosures, AISI's UK government evaluation, Mozilla's Firefox 150 release, Palo Alto Networks's frontier-AI defence reports, METR's time-horizon benchmark, the Sullivan and Cromwell legal memo on the US Treasury and Federal Reserve convening, and the conversations we have been having with regulated firms over the last fortnight.
