The Trump administration approved a select group of users, but Fable 5 is still nowhere in sight.
The White House standoff could have dire implications for the US AI industry.
Claude can join as a member of a company’s Slack to write and merge pull requests, locate sales numbers, analyze data, take on tasks delegated to it, and more, the company wrote in a blog post. To use it, people will tag @Claude in the Slack channel.

John Jumper, who has worked as a researcher at Google DeepMind since 2017, announced his departure from the company on X. In 2024, Jumper and Google DeepMind CEO Demis Hassabis won the Nobel Prize in Chemistry for developing an open-source AI model that predicts protein structures.
With the Mythos debacle, Anthropic gets its first taste of the Trump admin’s new AI regulation regime.
The Cybersecurity and Infrastructure Security Agency (CISA) gained access to the limited release cybersecurity-focused model last week, Nextgov/FCW reports. It’s just a little late, since the rest of the world has mostly moved onto the drama around the Trump administration’s block of the safeguarded public version of the model, Fable.
The AI design chatbot’s new editor has controls for directly dragging, resizing, and aligning elements, and more options for apps you can export to, including Adobe and Canva. Users can also work on design projects directly from the Claude Code terminal, or hand off software layouts from Design directly to Claude Code, where it picks up exactly where you left off, without a screenshot or a rebuild from scratch.
The government torpedoed Anthropic’s newest, most powerful model. Sources tell The Verge that the AI lab and other AI boosters spent the weekend trying to explain that Fable 5 wasn’t too powerful.
On an episode of The Verge’s “Decoder” podcast, Suleyman said that in Anthropic’s Claude Constitution, they “speculate about its consciousness and whether it has those feelings and is aware.” He called it both “dangerous” and a “philosophical failing,” adding, “We want AIs to be controllable, contained, accountable, aligned tools that serve humanity.”
RSI is also defined as an “AI system capable of fully autonomously designing and developing its own successor,” per Anthropic’s blog post. “We are not there yet, and recursive self-improvement is not inevitable. But it could come sooner than most institutions are prepared for.”

With this expansion of Anthropic’s Project Glasswing initiative, organizations in “several industries that weren’t well represented” in the initial cohort, like power, water, and healthcare, will get access to the model so they can use it to find security vulnerabilities.

The $65 billion Series H round gives Anthropic an eye-watering $900 billion valuation. That gives the company a higher valuation than OpenAI’s last valuation of $730 billion, according to The New York Times.
Anthropic says the funds will go toward advancing safety research, expanding compute, and scaling its products.
Anthropic’s fight with the Pentagon highlights the risks of autonomous warfare — but obscures just how close it is.
Upon request, “qualifying” customers can use things like skills, a Claude harness, and a threat model builder, Anthropic says as part of a bigger update about Project Glasswing.
Anthropic also plans to expand Project Glassing to “additional partners” and has published a dashboard of open source vulnerabilities disclosed by Mythos Preview.

Apparently, that SpaceX $15 billion per year megadeal isn’t even enough capacity for Claude, as The Information reports Anthropic is in early talks to rent Azure servers with Microsoft’s chips, and that “Anthropic has been steadily increasing its Azure usage.”
Like OpenAI, Microsoft’s arrangement with Anthropic runs hot and cold, but its Maia 200 chips are designed to help run existing models like Claude, even if they aren’t as fast at helping to train new ones.

Karpathy, who had also been on the founding team of OpenAI, says he will be working on R&D at Anthropic. Previously, he had been working on “new kind of school that is AI native,” and he says he’s still “deeply passionate about education” and plans to go back to it “in time.”
Researchers at the security firm Calif say they used Anthropic’s cybersecurity AI to create a privilege escalation exploit, the Wall Street Journal reports:
Last September, Apple said it leveraged its hardware and operating system expertise into a technology called Memory Integrity Enforcement (MIE), which it described as “the culmination of an unprecedented design and engineering effort, spanning half a decade.” With Claude, building the code that exploited the two MacOS bugs took five days, Calif says.
On Wednesday, the AISI, which evaluates AI models for the British government, said both Anthropic’s Claude Mythos Preview and OpenAI’s GPT-5.5 showed progress well above previous trends on cybersecurity testing. Separately, XBOW released data suggesting “frontier models have taken a major step forward in vulnerability discovery.”
Meanwhile, Microsoft said its multi-model agentic setup, MDASH, was used to discover 16 CVEs in this week’s Patch Tuesday updates and is the leader on the CyberGym security evaluation framework.
It’s a package of “connectors,” installed via a toggle switch, that allows Claude to work inside tools like Intuit Quickbooks, PayPal, Docusign, HugSpot, Google Workspace, and Microsoft 365. “It can plan payroll, close the month, run a sales campaign, chase invoices, and more,” per Anthropic’s blog post.

As the AI adoption in the legal field ramps up, Anthropic has announced that its AI chatbot can now connect to many of the apps used by lawyers, including DocuSign, Box, Thomson Reuters, Harvey, and more. “Claude reviews contracts, surfaces case law, and drafts across the tools your team already uses,” according to Anthropic.
