After two weeks of intensive negotiations with the US government, Anthropic has secured partial clearance to deploy its Claude Mythos 5 artificial intelligence model to more than 100 American institutions, including major corporations and government agencies. The decision, announced Friday by Commerce Secretary Howard Lutnick, marks an initial victory for the company, which was forced to disable access to Mythos 5 and its sibling Fable 5 in mid-June following an export control directive.
Root causes of the directive and Amazon's role
The exact reasons behind the block remain unclear, but according to sources close to the matter, the White House grew concerned after Amazon CEO Andy Jassy reportedly told Treasury Secretary Scott Bessent about a purported jailbreak that left Anthropic's models vulnerable to misuse. There were also fears about China potentially accessing Claude Mythos. The directive crippled the company, forcing an immediate suspension of services for all customers, including international ones. For comparison, similar regulatory pressures have occurred in the hardware sector, such as Micron suggesting Apple's aggressive price negotiations worsened the memory crisis, illustrating how power dynamics between major players can impact markets.

Deal details and release conditions
In a letter addressed to Anthropic's chief compute officer Tom Brown, Secretary Lutnick stated he had determined that "appropriate safeguards are in place to permit certain trusted partners to access the Claude Mythos 5 Model." The letter acknowledges "significant progress" in the daily talks between the government and the company. However, there is currently no word on when or whether Claude Fable 5 will be made available to the public again. People close to the negotiations indicate work is underway to extend clearance to Fable, but the timeline remains uncertain.

Comparison with OpenAI and future outlook
This news comes just hours after OpenAI's limited release of GPT-5.6, also authorized by the US government only for a small group of trusted partners. Anthropic confirmed the news on X, stating it continues to work with authorities to expand access to Mythos 5 and restore general use of Fable 5. According to the original report by Semafor, Lutnick's letter is silent on Fable 5, but talks are ongoing.
