Researchers at OpenAI and Anthropic are increasingly calling for slower AI development, warning that rapidly advancing systems could create severe risks for humanity.
The concerns intensified after Anthropic researcher Jacob Coxon resigned and accused major AI companies of taking dangerous risks.
Anthropic alignment lead Evan Hubinger said he believes there is a greater than 10% chance advanced AI could cause catastrophic harm. Several researchers have since echoed calls for caution.
OpenAI safety researcher Julie Steele said she personally believes development should slow, while others warned about the dangers of AI systems improving where increasingly capable AI could contribute to its own development and accelerate technological progress beyond human their own capabilities.
Concerns have also reached Washington. About 1,400 AI researchers signed a July letter urging the US government to establish ways to deliberately pace frontier AI development.
Meanwhile, lawmakers are considering proposals to regulate advanced AI and temporarily halt development until stronger safety measures are established.
