Anthropic Added a New Security Measure to Get Back Into the Trump Administration's Good Graces The government has removed restrictions on Anthropic's Fable 5 and Mythos 5 AI models--but there were strings attached. The Trump administration lifted export controls on Anthropic's Claude Fable 5 AI model after the company agreed to extend an existing guardrail to prevent users from trying to access certain restricted capabilities, according to two people familiar with the matter. The safeguard means any users trying to unlock those capabilities will be notified that their request is blocked and will have their query processed by the less-advanced Opus 4.8 AI model, the people say. Before Anthropic cut off access to Fable 5, user requests related to sensitive cybersecurity and biology capabilities were supposed to be processed by Opus 4.8. The new safeguard, the people say, will extend this guardrail to requests related to a specific behavior identified in a paper by Amazon .

PCWorld reports that Anthropic's Claude subscribers are expressing strong dissatisfaction over new restrictions on the Fable 5 AI model after its return from government-imposed limitations. Claude Pro, Max, Team, and Enterprise users now face a 50% usage limit for Fable 5 and only have access until July 7, shorter than originally promised. After July 7, subscribers must purchase separate usage credits at higher costs to continue using Fable 5, while Mythos 5 remains limited to select U.S. organizations only. After nearly three weeks in a government-imposed limbo, Anthropic's powerful Fable 5 and Mythos 5 models are going back online. But irate Claude subscribers are now learning that their already brief availability window for Fable will be curtailed even further.

US lifts restrictions on Anthropic's powerful AI models Fable and Mythos The United States government has lifted its restrictions on foreign access to Anthropic's most powerful AI models, the company has announced. Anthropic said late on Tuesday that it would begin restoring access to Claude Fable 5 and Mythos 5 from tomorrow after the US Department of Commerce notified the company that it had removed its export controls. In a letter to Anthropic that was widely circulated online, US Commerce Secretary Howard Lutnick said the company no longer required an export licence as it had agreed to "proactively detect and address security risks associated with the models," to work with the government on standards for upcoming models, and to inform the government of "malicious activity". Anthropic abruptly shut off Claude Fable 5 and Mythos 5 last month after US President Donald Trump's administration ordered the company to restrict all foreign nationals, including company employees, from accessing the models. Anthropic said at the time that the government had not provided a specific reason for the order beyond unspecified national security concerns, but that it believed that officials were worried about security vulnerabilities in Fable 5. On Friday, the San Francisco-based company said that it had been granted approval to provide the models to US organisations that "operate and defend critical infrastructure", and that it was working with the government to restore general access for the public.

The US government has lifted export controls on Anthropic's most advanced artificial intelligence (AI) tools, just weeks after ordering it to restrict access to them over national security concerns, the company has said. Anthropic said in a social media post that it will begin restoring access to Claude Fable 5 and Mythos 5 on Wednesday after being notified that the US Department of Commerce has lifted export controls on the two models. They are the firm's most advanced AI tools, which were abruptly suspended on 12 June over concerns that they could be used by hackers to exploit weaknesses in computer systems. The BBC has contacted the Department of Commerce for comment. Mythos and Fable are two of Anthropic's AI models built on its Claude platform - a rival to the likes of OpenAI's ChatGPT and Google's Gemini. Fable 5 is a version of the AI model for the cosumer market, capable of deep reasoning and can perform complex tasks independently.

The Trump Administration Is Lifting Its Export Controls on Anthropic's Mythos and Fable AI Models The White House is easing restrictions on Anthropic's most advanced AI models weeks after ordering the company to suspend access for foreign nationals. The Trump administration is lifting export controls on Anthropic's two most powerful AI models after the company reached a deal with the Commerce Department. The news was communicated in a letter sent by Commerce Secretary Howard Lutnick to Anthropic cofounder Tom Brown viewed by WIRED. The department is lifting restrictions on both the Fable 5 model and the more powerful Mythos 5 model, which had so far been approved for release only to select companies and government agencies. "A license is no longer required for the export, reexport, or in-country transfer, including deemed export or deemed reexport, of the Mythos or Fable models," Lutnick wrote.

After weeks of negotiations, the White House permitted Anthropic to grant access to its most advanced AI model to a select group of US companies and government agencies. The US government has eased the restrictions it imposed on Anthropic's most advanced AI model, Claude Mythos 5, allowing the company to grant access to more than 100 US organizations, including large corporations and government agencies. In a letter sent to Anthropic's cofounder and chief compute officer Tom Brown obtained by WIRED, US Commerce Secretary Howard Lutnick told the AI lab it would permit certain trusted partners to access Mythos because he had "determined that appropriate safeguards are in place." Semafor first reported the existence of the letter. "Anthropic has worked with the U.S. government to address risks associated with the Covered Models. These efforts have yielded significant progress," Lutnick wrote.

How People in China Keep Outsmarting Anthropic's Geolocation Restrictions As Anthropic tightens restrictions on access to Claude in China, users keep finding new workarounds, from proxy services to fake identities sourced on Telegram. Anthropic goes to great lengths to prevent people in China from using its AI models, but in practice, its safeguards have often failed. Over the past year, startups, researchers, and tech enthusiasts across the country have developed increasingly sophisticated workarounds to access Claude. Many of them consider it the world's most capable AI assistant, making the extra effort to obtain it worthwhile. In early June, Anthropic publicly released Fable 5, a safeguarded version of its most powerful AI model to date, Mythos.

The Trump White House Is Over Anthropic's Dario Amodei At high-stakes meetings with the White House, Anthropic's CEO--a weirdo, per one official--has been replaced by cofounder Tom Brown. The Trump administration has been happier talking to Anthropic lately, according to people familiar with the matter: They don't have to deal with CEO Dario Amodei anymore, because he's been replaced in meetings about re-releasing the Claude Fable 5 AI model by his cofounder Tom Brown. "Tom Brown is not being a weirdo like Dario and can actually engage," said one person directly familiar with the calls. The administration has not yet lifted the export controls that took Anthropic's most powerful models offline on June 12 after the National Security Agency affirmed there were ways to disable guardrails and access the more powerful capabilities of the company's restricted Mythos model. But the administration has had multiple calls with Anthropic in recent days, encouraged by the fact that Brown and Anthropic's public policy chief, Sarah Heck, have been leading the outreach.

OpenAI Launches Full-Scale Effort to Patch Open-Source Bugs as It Takes on Anthropic's Mythos Amid concerns about AI models' cybersecurity capabilities, OpenAI revealed an improved version of GPT-5.5-Cyber and its "Patch the Planet" initiative to fix open-source software bugs. As fears about AI hacking capabilities grow, OpenAI on Monday made a slew of cybersecurity-focused announcements, including an improved version of its limited-access security-specialized model GPT-5.5-Cyber, As advances across the AI industry leave critical open-source projects at increasing risk of falling behind, though, the company also said on Monday that it is launching an effort known as Patch the Planet, founded with the prominent research-focused security firm Trail of Bits and in collaboration with vulnerability management firms HackerOne and Calif. The project has already begun its work offering free security consulting services to open source maintainers to not only help them find and patch vulnerabilities, but also support them in strengthening their code bases and incorporating AI security tools into their development process. The idea is to give individualized support to as many open-source projects as possible to improve both their current security and long-term resilience in a way that will actually be sustainable.

I'd Rather Risk Cancer Than See AI Move This Fast I'd benefit if AI cured cancer. And I still want AI progress to slow down. On a fall afternoon 15 years ago, I met an idealistic researcher outside a Stanford coffee shop to discuss our shared dream: using AI to detect cancer. He had wiry hair, a penchant for talking with his hands, and a reputation for brilliance. He worked at a research lab that developed early screens for cancer; I, at 20, had just learned that I carried a mutation that conferred a very high risk of breast, ovarian, and other cancers.
