NEWSAR · AI

The US government has partially reversed a two-week-old order that suspended access to Anthropic's Claude Mythos 5 artificial intelligence model. Over 100 "trusted" US organizations, including many Fortune 500 companies, will now have access to the AI. This decision comes after initial concerns that the powerful AI could be misused by foreign adversaries for cyberattacks. The Trump administration has been taking an aggressive approach to overseeing the release of advanced AI models from companies like Anthropic and OpenAI due to these national security risks.
