On \u200cFriday the US government allowed Anthropic to release Mythos 5, to some \u201ctrusted\u201d US organisations, partly reversing the order. Mythos was only released to a small number of trusted partners for use in defensive cybersecurity.<\/p>\n
Lutnick said in a letter to Anthropic, seen by Reuters: \u201cAnthropic has agreed to proactively detect and address security \u200brisks associated with the models; to work diligently with the US government on protocols and standards and releases for Mythos, Fable, and future models; and to inform the US government of any malicious activity.\u201d<\/p>\n
The ban was seen as a toughening in the White House\u2019s stance towards the regulation of US AI companies, which had previously emphasised a light touch underpinned by a desire to beat China<\/a> in the supposed race to AI dominance.<\/p>\n The US government acted after it became aware of a report in which Amazon researchers found a method of bypassing Fable 5\u2019s safeguards to make it find software vulnerabilities, showing how such a weakness could be exploited \u2013 potentially by a malign cyber-attacker.<\/p>\n Anthropic responded to the export control by pulling the plug entirely, but it said it has now increased safeguards. It said in a blogpost: \u201cResearchers from the US Department of Commerce\u2019s Center for AI Standards and Innovation<\/a> (CAISI) have tested both our prior and new safeguards and agree that they are extraordinarily strong.\u201d<\/p>\n Anthropic said late on Tuesday it would \u201cscale up our government collaboration\u201d and \u201cstand up dedicated Anthropic teams to work on shared government priorities\u201d.<\/p>\n Last week intelligence agencies in Australia, the US, the UK, New Zealand and Canada warned that<\/a>, while AI \u201cwould help us improve cyber defence over time, it also accelerates the speed, scale, and sophistication of cyber threats\u201d.<\/p>\n The warning by Five Eyes agencies said: \u201cFrontier AI models are anticipated to exceed current industry expectations, fundamentally transforming both offensive and defensive cyber capabilities.
