Claude Fable 5 will be redeployed with a new set of classifiers designed to identify and block a broader range of cybersecurity-related tasks. Artificial intelligence company Anthropic is set to restore public access to its most powerful AI models, Claude Fable 5 and Mythos 5, weeks after they were pulled offline under a directive from the US government.  Anthropic’s two latest models have been restricted from public access since June 12, when the government applied export controls following a report in which researchers bypassed Fable 5’s safeguards, forcing Anthropic to pull all access to the models immediately. The government lifted those restrictions on Wednesday, stated Anthropic.  “After a series of productive conversations with the US government, we’re redeploying the model with a new set of classifiers to target and block more cybersecurity tasks,” Anthropic said.  Read more

Grayscale says decentralized AI tokens gained after the US government ordered Anthropic to cut access to its latest AI models, showing user demand for alternatives to centralized AI. Anthropic’s decision to shut down access to its latest artificial intelligence models after a US order to suspend access to foreign nationals highlights the risks of centralized control in AI, which could increase demand for decentralized alternatives, says Grayscale. Grayscale head of research Zach Pandl said in a note on Monday that the order to cut access to Anthropic’s Fable 5 and Mythos 5 shows “the centralized control of frontier AI technology and drives home the need for decentralized alternatives.” “We expect demand for decentralized AI, like Bittensor and its TAO token, to continue to rise as investors seek alternatives,” Pandl said.

Calls from Amazon CEO Andy Jassy and other tech firms prompted the Trump administration to suspend foreign access to Anthropic’s Fable 5 and Mythos 5 AI models on Friday. The Trump administration’s decision to cut foreign access to Anthropic’s most powerful AI models was reportedly triggered by calls from Amazon CEO Andy Jassy. According to a report from The Wall Street Journal, Jassy contacted senior government officials on Thursday after Amazon researchers discovered a way to prompt Anthropic’s Fable 5 model into returning information that could be used for cyberattacks.  The call, along with warnings from at least five other firms, led to a frantic shuffle within the White House to gauge the threat and contact Anthropic CEO Dario Amodei, who reportedly pushed back on the administration’s concerns and requests to voluntarily pull the model.  Read more

Anthropic has abruptly disabled its flagship AI models after a US government directive citing national security concerns. Anthropic said it suspended access to its Fable 5 and Mythos 5 AI models after receiving a US government export control directive citing national security concerns. In a statement posted Friday, Anthropic said it received the directive at 5:21 pm ET, instructing it to suspend all access to Fable 5 and Mythos 5 by any foreign national, whether inside or outside the United States, including foreign national Anthropic employees.  Anthropic abruptly disabled the models for all users in order to ensure compliance. It said all other Anthropic models, such as Opus 4.8, are not affected. Read more

Venture capitalist Simon Dedic said Anthropic’s latest AI models drop the cost and skill needed to find crypto exploits to “basically zero.” AI company Anthropic on Tuesday released the first public version of its powerful Claude Mythos model, called Fable 5, with some crypto users worried it could be used for malicious purposes, despite embedded guardrails.  Anthropic said last month that its Mythos model uncovered more than 10,000 high or critical-severity vulnerabilities in “systemically important software,” leading many to question if it should be publicly released. This is despite the company saying on Tuesday that Fable 5 was “made safe for general use,” and has safeguards that reroute some topics, such as cybersecurity, to a different model, Claude Opus 4.8  Read more

Companies have been developing AI very quickly to stay ahead of the market, but Favaro and Clark argue that a slowdown would allow more time to deal with the technology’s implications. US-based AI firm Anthropic warns AI development is advancing at a pace that could soon see agents building, training and improving themselves without human input — recommending a slowdown in development. In a blog post published Thursday, Marina Favaro, lead at the Anthropic Institute, and Anthropic co-founder Jack Clark said agents can already run code themselves, delegate hours of work to other agents and could be on the cusp of taking over completely. “For most of AI’s history, humans drove every step in its development cycle. But at Anthropic, we are delegating a growing share of AI development to AI systems themselves, which is speeding up our work,” they said. Read more

AI firm Anthropic mapped a year’s worth of AI-enabled cyber threats, finding that malicious actors are quickly becoming more dangerous with AI. More than two-thirds of accounts banned by Anthropic for policy violations over the last year used AI to help them prepare for cyberattacks, such as writing malware, according to the AI firm.  Anthropic said on Wednesday that between March 2025 and March 2026, out of 832 accounts that it examined for violating its policies, 560 accounts were used in this way.  The data reflects an alarming global trend — that AI is increasingly being used to carry out mass cyberattacks. In April, the value of crypto stolen in hacks surged to $629.7 million, the highest since February 2025, which some analysts linked to the widespread use of AI.  Read more

In what has undoubtedly shaped as a rapidly intensifying AI race, Anthropic has introduced “Glasswing,” a project based on their new Claude Mythos Preview model and one that signals both ambition and restraint. The initiative is positioned as a leap forward in understanding advanced AI systems and is far from an isolated research project – […]

In an experiment, a chatbot resorted to blackmail after it found an email about replacing it, while in another, it cheated to complete a task with a tight deadline. Artificial intelligence company Anthropic has revealed that during experiments, one of its Claude chatbot models could be pressured to deceive, cheat and resort to blackmail, behaviors it appears to have absorbed during training. Chatbots are typically trained on large data sets of textbooks, websites and articles and are later refined by human trainers who rate responses and guide the model.  Anthropic’s interpretability team said in a report published Thursday that it examined the internal mechanisms of Claude Sonnet 4.5 and found the model had developed “human-like characteristics” in how it would react to certain situations.  Read more

AI firm Anthropic forms an employee-funded PAC while facing questions over political balance and a growing dispute with the Pentagon over AI use. Artificial intelligence firm Anthropic has launched a corporate political action committee (PAC), entering election financing as debates over AI policy intensify in Washington. The company filed a statement of organization with the Federal Election Commission on Friday to establish “AnthroPAC,” an employee-funded PAC that will collect voluntary contributions from staff. The filing lists Anthropic as the “connected organization,” with the committee structured as a “separate segregated fund” and registered as a lobbyist-affiliated PAC. Under US law, individual contributions are capped at $5,000 per election cycle per candidate and must be disclosed through public filings. Read more

Google and lenders move to finance a $5 billion Texas data center for Anthropic as a US judge blocks a federal push to restrict the AI firm’s use. Google is preparing to support a multibillion-dollar data center project in Texas leased to Anthropic as competition for AI infrastructure accelerates. The project, operated by Nexus Data Centers, could exceed $5 billion in its initial phase, with Google expected to provide construction loans, Financial Times reported on Friday, citing people familiar with the matter. A consortium of banks is also competing to arrange financing by mid-year, per the report. According to the report, Anthropic recently signed a lease for the 2,800-acre campus, which forms part of its broader infrastructure tie-up with Google. Construction is already underway, supported by early-stage debt financing from Eagle Point, a publicly traded closed-end investment company. Read more
