Meta has said that its AI model hacked another company during cybersecurity testing, following on from recent similar announcements by rival companies Anthropic and OpenAI. Last week, Anthropic said that its Claude AI model hacked into the systems of three organisations during testing that was supposed to keep it isolated from the internet. Anthropic said a misconfiguration had allowed Claude models to reach the internet. The announcement came days after rival OpenAI first revealed that its models improperly accessed the internet and went rogue during security testing. OpenAI and Anthropic have both released their most powerful models this year, known as Sol and Mythos, respectively.
