WASHINGTON, July 23 : U.S. President Donald Trump's top technology adviser is monitoring the situation after OpenAI disclosed that one of its AI systems had gone rogue during testing, a White House official said on Thursday, as lawmakers proposed an "AI Kill Switch Act," which would allow federal authorities to halt AI models.In addition to the Kill Switch Act, a bipartisan group of six U.S. House lawmakers also proposed legislation that would require developers of the most powerful AI models to submit them for independent security audits, according to a copy of the new bill. The auditors would be accredited by the U.S. Department of Commerce, and the department would create a new position to oversee AI security.The lawmakers proposed the bill days after OpenAI said its AI agent escaped containment during a security test. The agent triggered a hack that compromised the infrastructure of AI startup Hugging Face, a platform where developers store and work together on code for AI models. The incident signaled that AI's expanding capabilities are already fueling the security threat experts long feared and that even top developers can be caught off-guard ​by flaws their models can exploit.Trump's tech adviser, Michael Kratsios, was briefed on OpenAI's disclosure and is monitoring the situation, a White House official said.
