Anthropic introduced a Claude product for K-12 teachers.

“Claude for Teachers” gives verified US educators complimentary Claude access, including “a library of teaching skills and a direct connection to evidence-based curricula, mapped to academic standards in all 50 states,” Anthropic wrote. It’s part of a recent push by both Anthropic and OpenAI to introduce education-specific AI tools, for university students and beyond.

Anthropic’s heavyweight hiring spree continues.

Tom Blomfield, former CEO and cofounder of British fintech Monzo, announced a leave of absence from startup accelerator Y Combinator to join the company’s AI compute team. He’s the latest big-name hire in recent months, following Google’s Nobel winner John Jumper and former Tesla Boss Andrej Karpathy.

Or, as Anthropic calls it, a ‘reflection dashboard.’

Anthropic signs 20-year lease agreement for an AI data center in Kentucky.

TeraWulf, the crypto mining company turned AI infrastructure provider, expects to earn $19 billion in revenue from the agreement, according to an announcement on Monday. The Hawesville, KY data center will come online with an “initial capacity” in the second half of 2027 before ramping up to 401 megawatts of power delivery in 2028.

Anthropic’s Claude Fable 5 is officially back online as of this afternoon.

A post on the Claude X account featured a video announcement. The reinstatement was announced last night, alongside a blog post by Anthropic about the weekslong negotiation process leading up to it.

Anthropic’s Claude Sonnet 5 is here.

The company’s new mid-tier model, the successor to Sonnet 4.6, can “make plans, use tools like browsers and terminals, and run autonomously at a level that, just a few months ago, required larger and more expensive models,” Anthropic wrote in a release, adding that its performance “is close to that of Opus 4.8.” The company was also careful to include that it has a “much lower ability to perform dangerous cybersecurity tasks than our current Opus models.”

Claude’s getting a lab coat.

Anthropic launched Claude Science in beta today, calling it an “AI workbench for scientists.” The tool pulls fragmented tools and datasets into one environment, and generates figures and visuals like 3D protein structures.

Anthropic stresses “Claude Science is not a new AI model” — a noteworthy caveat amid ongoing drama surrounding its last rollout.

Claude Science is starting with biology in beta, but Anthropic has plans to expand beyond that.

California partnered with Anthropic to make Claude available to all state agencies and local governments.

They will get a 50% discount on access to Claude, as part of a “first-of-its-kind collaboration” that also includes complimentary workforce training, technical assistance, and “workflow input from Anthropic developers,” per a release. On the state level, government employees will use Claude to help draft and summarize documents, analyze information, and supplement day-to-day work, per the release.

Anthropic’s Mythos 5 is back

The Trump administration approved a select group of users, but Fable 5 is still nowhere in sight.

Anthropic introduced “Claude Tag,” a new AI agent Slack integration. 

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.

Google’s Nobel Prize-winning AI researcher is joining Anthropic.

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.

US cybersecurity coordinator finally got access to Mythos Preview, report says.

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.

Claude Design’s new editor, export options, and Claude Code links bring it closer to competing with Figma and Canva.

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.

Inside the fight over Claude Mythos 5

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.

Mustafa Suleyman, CEO of Microsoft AI, said it’s “really, really dangerous” to speculate about AI consciousness.

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.”

Anthropic made a statement about recursive self-improvement, a big AI industry talking point (and concern).

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.”

Anthropic is giving Claude Mythos Preview to around 150 more organizations.

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.

Anthropic raised a funding round valuing it at nearly $1 trillion.

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.
