the incidents after reviewing more than 140,000 tests following OpenAI&#8217;s disclosure on 21 July that its agents had hacked another AI company, Hugging Face.<\/p>\n<p class=\"ssrcss-1q0x1qg-Paragraph e1jhz7w10\">Anthropic urged other AI labs to perform similar reviews to better understand the risks of their models&#8217; capabilities.<\/p>\n<p class=\"ssrcss-1q0x1qg-Paragraph e1jhz7w10\">The San Francisco-based firm also said it has alerted the three companies that were hacked about the incidents.<\/p>\n<p class=\"ssrcss-1q0x1qg-Paragraph e1jhz7w10\">Anthropic said in a statement that it is &#8220;approaching the fixes as if the responsibility were ours alone.&#8221;<\/p>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<div
