When OpenAI¡¯s advanced artificial intelligence models breached AI startup Hugging Face¡¯s internal systems last week, they spent mere hours carrying out a hack that would have taken a skilled human far longer, people familiar with the matter said.

Typically, even a talented hacker would need a couple of weeks to complete an attack like this, said the people, who asked not to be named in order to discuss details that have not been publicly released.

OpenAI has been in contact with the U.S. government since learning that the breach occurred, one of the people added.
