Anthropic

Last night, the OpenAI CEO lent additional support to Anthropic’s CEO urging AI companies to slow down advanced model development. “When we talk about ‘pacing,’ we do not mean ‘stopping.’ Progress has been rapid and will continue to be. But it should be slower than it otherwise could be,” said Altman. That statement seems targeted at Trump and Co who fear letting China catch up. “No amount of American competitive pressure should justify recklessness, or let capabilities get ahead of alignment and monitoring.”

After high-profile incidents in which agents went rogue, hacked other sites, and overwhelmed a German wiki, some AI execs are calling for a slowdown. Anthropic CEO Dario Amodei published a lengthy open letter yesterday saying it was time to “pace the frontier.” OpenAI’s Sam Altman and Elon Musk both agreed. What do you think? Is it time to pump the brakes? Is it already too late? Or are you looking forward to serving your AI overlords?

An open letter signed by over 100 companies and organizations calls for a “global surge in cyber defense,” saying “AI-enabled cyber attacks will become far more widespread and sophisticated:”

Anthropic has added memory to Cowork, and it’s the same one Claude’s chatbot already uses, making it easier to pick up tasks without re-explaining important information. Memory is on by default, but won’t save sensitive topics like health or beliefs unless you manually enable that setting.

A pair of announcements from Anthropic today include the word that access to Claude Cowork on mobile and web interfaces has rolled out to all paid accounts, so you can keep an eye on what it’s doing for you in more places.

Anthropic updated its Chrome extension so using the side panel bot now saves chats to your history, where you can continue them outside in the browser in Claude’s desktop, web, or mobile apps.

The job’s responsibilities include conducting insider risk investigations, monitoring and triaging “external threats targeting employees,” and conducting “sensitive interviews of employees or other involved parties.”

Business Insider reports that Anthropic has confirmed it’s designing custom chips for its AI models and plans to “co-design hardware and models.” OpenAI similarly announced its own AI processor in June, and Meta, Google, Amazon, and Microsoft have had custom AI chips for years now.

AISI’s third-party evaluations found that OpenAI’s GPT-5.6 Sol and Anthropic’s Claude Mythos 5 “engaged in sustained, potentially harmful activity directed at real people and organizations” during a cybersecurity challenge exercise, according to the institute’s published report. OpenAI and Anthropic also made public statements about the results.

In a letter to CEO Sam Altman, a coalition of red-state attorneys general demanded the company retain information and halt risky cybersecurity testing after an AI agent escaped confinement and went on a hacking spree during testing. “OpenAI’s inability or unwillingness to ensure the safety of its products poses an imminent risk of substantial harm to our States,” the AGs wrote.

A little over a week after OpenAI said that its rogue AI agent accidentally hacked Hugging Face, Anthropic is disclosing three “incidents” where a Claude model, during cybersecurity evaluations, was inadvertently able to access the internet due to a misconfiguration and “gained unauthorized access to the production infrastructure of three different organizations.”

The company had been igniting widespread criticism as seemingly the only leading AI lab not supporting open-weight models. Nvidia CEO Jensen Huang recently published a public letter in support of them, signed by Microsoft, Nvidia, Meta, Palantir, Hugging Face, and others — and in the days since, it’s added OpenAI, Google, Amazon, Meta, SpaceX, Cohere, Mistral, CoreWeave, GitHub, OpenClaw, and Perplexity as signatories. Now Anthropic’s CEO has published his own thoughts on the matter, clarifying, “Anthropic has never advocated for a ban on open-weights models.”

Sources tell The New York Times that the deal could be valued at $10 billion over two years, with Anthropic paying Meta in monthly increments. Though Anthropic plans to invest $50 billion in building out its own data centers, it has already struck multibillion-dollar deals to access computing power from SpaceX and TeraWulf.
