US releases powerful Anthropic model Mythos to some US companies (www.semafor.com)

The US government has lifted its ban on Anthropic's advanced Claude Mythos 5 AI model, allowing over 100 US institutions, including prominent companies and government agencies, to access this powerful tool. This decision follows recent export controls imposed due to security concerns that the AI could be misused, prompting a shutdown of Mythos and its sibling model, Fable 5. Commerce Secretary Howard Lutnick highlighted that the government is now confident in the safety protocols established by Anthropic, which has promised to collaborate with federal authorities on AI deployment standards. This development is significant for the AI/ML community as it represents a shift in regulatory stance, offering a controlled framework for the release of cutting-edge AI technologies while aiming to maintain the US’s leadership in the global AI race. The clearing of Mythos also coincides with the release of OpenAI's GPT-5.6, intensifying the competition among leading AI firms. The new arrangement eliminates the need for a license to export Mythos to designated entities, but many international users remain uncertain about when they will gain access to these highly anticipated models, highlighting the growing tension around AI governance and global technology dependence.
