Anthropic Updates Prospectus: Admits It Previously Failed to Timely Identify AI R&D Acceleration, and Bans Claude from Fully Autonomously Designing Next-Generation Models
Anthropic submitted an updated prospectus (S-1/A) to the U.S. SEC, changing the first version's "may be unable to identify before R&D significantly accelerates" to "has previously failed to identify," acknowledging that AI R&D acceleration has already genuinely occurred internally. The filing discloses that by September of this year, more than 90% of code in the internal codebase was generated by Claude, the average daily code commits per engineer rose from 35 times the 2024 average to more than 45 times, and internal spending on calling Claude, at public list prices, grew more than 250-fold from January to September. Page 188 explicitly states that Claude will not be allowed to fully autonomously design and build next-generation frontier models without human oversight, and that it is considering requiring key decisions to be reviewed and signed off by humans.
