The restrictions were imposed two weeks ago amid concerns about China's access to the model and a reported jailbreak. Commerce Secretary Howard Lutnick cited significant progress in talks with Anthropic as the basis for the partial lift.", "body_md": "Following an [export control directive two weeks ago](https://9to5mac.com/2026/06/12/anthropic-pulls-claude-mythos-5-and-claude-fable-5-following-us-government-directive/) that forced Anthropic to disable access to Claude Fable 5 and Claude Mythos 5 for all customers, the company scored a partial victory in a deal with the US government earlier tonight. Here are the details.\n\n## Anthropic makes progress with the US government\n\nAs reported by [ Semafor](https://www.semafor.com/article/06/27/2026/us-releases-powerful-anthropic-model-mythos-to-some-us-companies), the US government has partially lifted the export control directive issued against Anthropic last week.\n\nThe exact reasons that led to the directive remain unclear, but [most reports](https://www.theverge.com/ai-artificial-intelligence/950412/anthropic-trump-adminstration-claude-mythos-fable-5-export-controls) indicate that the government grew concerned after Amazon CEO Andy Jassy told U.S. Secretary of the Treasury Scott Bessent about a purported jailbreak that left Anthropic’s models vulnerable to misuse. There were also reports that the White House had grown concerned about [China’s access to Claude Mythos](https://www.semafor.com/article/06/13/2026/white-house-move-to-limit-anthropic-linked-to-concerns-about-chinese-access-to-mythos).\n\nWhatever prompted the restriction, Anthropic and the US government spent the past two weeks working toward a resolution. Those talks yielded their first result tonight, with the government partially lifting the restrictions and allowing Anthropic “to release it to more than 100 US institutions, including major companies and government agencies”, according to [ Semafor](https://www.semafor.com/article/06/27/2026/us-releases-powerful-anthropic-model-mythos-to-some-us-companies).\n\nFrom the [report](https://www.semafor.com/article/06/27/2026/us-releases-powerful-anthropic-model-mythos-to-some-us-companies):\n\n“I have determined that appropriate safeguards are in place to permit certain trusted partners to access the Claude Mythos 5 Model,” Commerce Secretary Howard Lutnick wrote to Anthropic’s chief compute officer Tom Brown Friday, citing “significant progress” in the intense, daily talks between the government and the company since the block went into effect.\n\nRight now, there is no word on when (or whether) Anthropic customers should expect Claude Fable 5 to be made available as well. [ Semafor](https://www.semafor.com/article/06/27/2026/us-releases-powerful-anthropic-model-mythos-to-some-us-companies) said Lutnick’s letter “is silent on Fable 5,” but the report notes that “people close to the talks said they are moving toward releasing Fable as well, though that timeline is unclear.”\n\nTonight’s news comes just hours after [OpenAI’s limited release](https://9to5mac.com/2026/06/26/openai-upgrading-chatgpt-and-codex-with-new-gpt-5-6-models-in-limited-release/) of its new GPT-5.6 models. As the company explained earlier today, the models are initially available only to a small group of trusted partners approved in coordination with the US government, with a broader rollout planned for the coming weeks.\n\nTo read *Semafor*’s original report, [follow this link](https://www.semafor.com/article/06/27/2026/us-releases-powerful-anthropic-model-mythos-to-some-us-companies).\n\n#### Worth checking out on Amazon\n\n[Geoffrey Cain – ‘Steve Jobs in Exile’](https://amzn.to/4v3CS5Q)[David Pogue – ’Apple: The First 50 Years’](https://amzn.to/46Y3nQj)[MacBook Neo](https://amzn.to/47vJmkn)[Logitech MX Master 4](https://amzn.to/3KmIQN7)[AirPods Pro 3](https://www.amazon.com/Apple-Cancellation-Translation-Headphones-High-Fidelity/dp/B0FQFB8FMG?tag=marcmendes-20)[AirTag (2nd Generation) – 4 Pack](https://amzn.to/4sewc3a)[Apple Watch Series 11](https://amzn.to/46VomDB)[Wireless CarPlay adapter](https://www.amazon.com/gp/product/B0F6T6N2B1?tag=marcmendes-20)\n\n*FTC: We use income earning auto affiliate links.* [More.](https://9to5mac.com/about/#affiliate)\n\n[our homepage](http://9to5mac.com/)for all the latest news, and follow 9to5Mac on\n\n[exclusive stories](https://9to5mac.com/feature/exclusive/),\n\n[reviews](https://9to5mac.com/guides/review/),\n\n[how-tos](https://9to5mac.com/guides/how-to/), and\n\n[subscribe to our YouTube channel](https://www.youtube.com/9to5mac)", "url": "https://wpnews.pro/news/anthropic-cleared-to-release-claude-mythos-5-to-over-100-us-institutions", "canonical_source": "https://9to5mac.com/2026/06/26/anthropic-cleared-to-release-claude-mythos-5-to-over-100-us-institutions/", "published_at": "2026-06-26 23:03:33+00:00", "updated_at": "2026-06-26 23:08:01.208696+00:00", "lang": "en", "topics": ["ai-policy", "ai-safety", "large-language-models"], "entities": ["Anthropic", "Claude Mythos 5", "Claude Fable 5", "US government", "Howard Lutnick", "Amazon", "Andy Jassy", "Scott Bessent"], "alternates": {"html": "https://wpnews.pro/news/anthropic-cleared-to-release-claude-mythos-5-to-over-100-us-institutions", "markdown": "https://wpnews.pro/news/anthropic-cleared-to-release-claude-mythos-5-to-over-100-us-institutions.md", "text": "https://wpnews.pro/news/anthropic-cleared-to-release-claude-mythos-5-to-over-100-us-institutions.txt", "jsonld": "https://wpnews.pro/news/anthropic-cleared-to-release-claude-mythos-5-to-over-100-us-institutions.jsonld"}}
