- Anthropic advocates that it would be good for the world to have the option to slow or temporarily pause frontier AI development.
- More than 80% of the code merged into its production codebase is now written by Claude, significantly increasing from low single digits before the launch of Claude Code in 2025.
Anthropic has suggested a new approach to the rapidly evolving field of frontier artificial intelligence, advocating for the ability to slow or temporarily pause its development.1
This recommendation comes amid its latest milestone: more than 80% of the code in its production codebase is now authored by its AI model, Claude. This is a significant increase from the low single digits reported before the launch of Claude Code in 2025.
The company’s call for moderation emphasizes its belief that if similar systems were to adopt a temporary halt, it could lead to a more responsible advancement in AI technology. They stated, if such systems existed, they anticipate a need to slow down or temporarily pause if other developers at the frontier also did so in a verifiable manner.
Notably, growth in Claude's capabilities has been remarkable. In contrast to 2024, Claude progressed from completing software tasks that took humans minutes to accomplishing tasks that span several hours and even extending up to 12 hours in duration more recently. This dramatic improvement corresponds with reports that typical engineers merged eight times as much code per day in the second quarter of 2026 compared to 2024, showcasing the efficiency leap attributed to Claude’s evolving functionality.
“Anthropic is pushing for mechanisms to slow or temporarily pause frontier AI development. Meanwhile, Claude has significantly increased its contribution to software code, now accounting for over 80% of the merged production codebase.”
