Sept 29 (Reuters) - California Governor Gavin Newsom

signed a state law on Monday that would require ChatGPT

developer OpenAI and other big players to disclose their

approach to mitigating potential catastrophic risk from their

cutting-edge AI models.

California is the home to top AI players including OpenAi

Alphabet's Google, Meta Platforms ( META ), Nvidia ( NVDA )

and Anthropic and with this bill wants to be seen as

leading on regulation of an industry potentially critical to its

economy in the years ahead.

"California has proven that we can establish regulations to

protect our communities while also ensuring that the growing AI

industry continues to thrive," Newsom said in a press release on

the law.

Newsom's office said the law, known as SB 53, fills the gap

left by Congress, which so far has not passed broad AI

legislation, and provides a model for the U.S. to follow.
