A fairness debate has emerged after OpenAI released a cybersecurity model with performance rivaling Anthropic's Mythos, yet faces little political pressure, unlike Anthropic. Anthropic has been at odds with the Trump administration since clashing with the US Department of Defense over AI use, prompting criticism that AI regulation is driven by political interests. The Trump administration has restricted access to Anthropic's Mythos and Fable not only overseas but also for foreigners residing in the United States, harming US companies employing foreign workers. OpenAI's updated GPT-5.5-Cyber scored 85.6% on "CyberGym," while Anthropic's Mythos 5 scored 83.8%. Anthropic customers are filing lawsuits; Region Legal Tech challenged the government's order in a federal court in Washington, D.C., stating the measure cut off access for team members in Canada, causing immediate and irreparable harm. US Commerce Secretary Howard Lutnick sent a letter to Anthropic on the 12th ordering it to block foreign access to Fable 5 and Mythos 5, which are now fully banned for overseas users and foreigners in the US.
