Anthropic's own safety report says 133 million contractor conversations ran without its bioweapon-related filters switched on.
The company published its second Risk Report on August 14, covering the period through July 15. Buried inside it: contractor chats ran at that 133-million-conversation scale while filters meant to catch bioweapon-related material were not active. Axios got Anthropic on the record and led most of the coverage on a different figure instead, the company's upgraded estimate of catastrophic harm from misalignment in high-stakes settings, moved from "very low" to "low." That framing shaped nearly every story that followed.
The filter gap is the more concrete disclosure here. A misalignment rating is a judgment call about a hypothetical failure mode. A hundred and thirty three million unfiltered contractor chats is a specific, countable thing that already happened, from a lab that markets itself on catching exactly this kind of risk before it ships.
Self-graded report cards are still report cards, and the fine print is where the real story usually lives.
