US Government Clears Mythos 5 for Limited Release
The United States government has lifted its block on Anthropic's powerful Claude Mythos 5 AI model, allowing the company to release it to more than 100 US institutions including major corporations and government agencies. Commerce Secretary Howard Lutnick informed Anthropic in a letter Friday that he had "determined that appropriate safeguards are in place to permit certain trusted partners to access the Claude Mythos 5 Model," according to documents reviewed by multiple news organizations.
The decision marks a significant reversal from the June 12 emergency order by the Commerce Department's Bureau of Industry and Security (BIS), which ordered Anthropic to suspend access to Mythos 5 and its safer variant Fable 5 for all foreign nationals. Anthropic, unable to reliably verify user nationality, disabled both models globally.
What Makes Mythos 5 Different From Other AI Models
Mythos 5 represents a generational leap in AI capabilities. The model achieved 93.9% on SWE-bench Verified and 77.8% on SWE-bench Pro - both record-breaking scores. What sets Mythos apart is its exceptional cybersecurity capability - it can autonomously discover and chain together zero-day vulnerabilities in production software, including a remote crash vulnerability in OpenBSD that had gone undetected for 27 years.
The model runs on Nvidia H200 GPU clusters, pricing at $10 per million input tokens and $50 per million output tokens.
Why the US Initially Blocked Access
The June 12 suspension was triggered by a government report describing a technique that could bypass Fable 5's safeguards. Anthropic disputed the characterization, calling it a "narrow misunderstanding." The suspension had immediate global consequences - Anthropic filed a lawsuit challenging the directive, arguing that competitive ground lost during a suspension cannot be regained.
India's Diplomatic Push for Stable AI Access
At the Pax Silica Summit in Washington, MeitY Secretary S. Krishnan delivered a clear message to US officials: "We can't have abrupt cutoffs." India's concern stems from the integration of AI tools into national digital infrastructure. A sudden loss of access to frontier AI could halt long-term initiatives.
India's IT industry already generates $10-12 billion in AI services revenue, and the country has positioned itself as an AI-first economy through the IndiaAI Mission. Krishnan stated that India received a verbal assurance from the US that advanced AI access would not be cut off without notice.
Broader Implications for AI Supply Chains
The incident has intensified the debate over AI supply chain resilience. Krishnan warned against over-reliance on any single source. As India builds its own AI and quantum technology capabilities, the episode has reinforced the importance of sovereign AI. Zoho founder Sridhar Vembu called the restriction a "wake-up call."
What the Limited Release Means
The current release is limited to trusted partners within the United States. Anthropic is working to restore broader access. For India, the episode has accelerated discussions around sovereign AI infrastructure. Policy experts have noted that "American AI models are bound to American geopolitics."
