## What the duty requires

A large frontier developer must transmit to the California Office of Emergency Services, on the periodic schedule the statute sets, a summary of any assessment of catastrophic risk that results from the internal use of its frontier models. This covers risks arising before public deployment, such as during internal evaluation or use of the model to accelerate research, and complements the public transparency report.

## What an organisation does about it

Schedule a recurring internal-use risk assessment and a state submission with a fixed owner in the safety team.
