OpenAI slows advanced AI development after cyberattack

ChatGPT creator OpenAI said Tuesday that it was tapping the brakes on development of its most advanced AI model and tightening internal controls, a month after revealing a cyberattack carried out by one of its rogue models.

OpenAI is a key player in the rapid global buildout of artificial intelligence infrastructure and tools that some have likened to an arms race.

The company said in a blog post on Tuesday that it was holding off on conducting the biggest AI training run it had ever planned while it checks that the model that would result — called Astra — would behave as expected.
