The company says this risk is covered by its Responsible Scaling Policy.

The new Risk Factors language says Anthropic has in the past not identified, and may in the future not identify, a significant acceleration in its rate of development until after it has occurred.

Anthropic also states that it has not designated any current model as exceeding this threshold and that it continues to assess the underlying data. The filing says the company does not anticipate being able to safely use Claude to fully autonomously design and build successive generations of frontier models without meaningful human supervision. It adds that Anthropic is considering updates to its Responsible Scaling Policy to keep humans in control of frontier model development.
