Anthropic's amended S-1 says it may imminently hit RSP's "dramatically accelerated progress" threshold

Sharing a risk-disclosure excerpt from Anthropic's amended S-1 filing, danielmac8 highlights a striking admission: Anthropic's internal estimates and expectations indicate it may imminently meet its Responsible Scaling Policy's definition of "dramatically accelerated progress attributable to AI" — though no current models have been designated as exceeding the threshold yet.

Key points from the filing:

Using AI to accelerate its own R&D may push model capabilities faster than safety, alignment, and security measures can be developed and validated; Anthropic relies on lagging indicators and admits it has failed to identify, and may miss, significant acceleration until after it occurs.
Meeting the capability threshold would trigger further RSP reports; past precautionary measures included delaying releases and limiting availability (e.g., Mythos via Project Glasswing), and future measures may become more frequent and costly.
The company acknowledges these safety constraints could slow capability gains relative to unconstrained competitors and adversely affect its competitive position, revenue growth, and results of operations.
