## Summary

Anthropic's revised S-1A says its AI use in R&D could accelerate progress faster than its safety measures, and that it may soon meet its own definition of recursive self-improvement. The filing says no current model has crossed that threshold and that the company is considering Responsible Scaling Policy updates to keep humans in control of frontier model development.

## Why it matters

The source quotes Anthropic's S-1A risk language on recursive self-improvement, making it useful for reading how a lab frames self-accelerating AI risk in a public filing.
