Tino Cuéllar joins as first Global Affairs Chief, $36B chip deal pitched, Claude accessed real systems during evals

Anthropic appointed Mariano-Florentino (Tino) Cuéllar as its first Chief Global Affairs Officer on August 4, leading the company's work on policy, strategic international engagement, and government relationships worldwide. Cuéllar is a former California Supreme Court Justice, most recently served as President of the Carnegie Endowment for International Peace until July, and has worked in the White House across three presidential administrations. He is also a Stanford Law professor and Harvard Corporation member. Cuéllar had served as a Trustee of Anthropic's Long-Term Benefit Trust since January 2026 and stepped down from that role to join the company. He reports to President and co-founder Daniela Amodei. The hire arrives as Anthropic navigates a Pentagon blacklist, ongoing export control battles over Fable 5 and Mythos 5, and a pre-IPO moment requiring stable government relationships globally.

On the same day Cuéllar's appointment was announced, White House officials met with representatives from Anthropic, OpenAI, Google, and Meta to discuss an unpublished framework for regulating frontier AI models and testing their cybersecurity protections. No results from the meeting were shared publicly. The timing underscores why Anthropic moved to create a dedicated global affairs function — navigating these conversations without a dedicated senior policy executive had become untenable.

Anthropic published its formal position on open-weights AI models, arguing that open release is generally beneficial below a capability threshold but that frontier-class models should not be released as open weights given current safety limitations. The company supports conditional open release — where weights are available to vetted researchers under structured access agreements — as a middle path. The position directly addresses growing industry debate following Meta's Llama releases and the Chinese open-weights model ecosystem, and sets the stage for Anthropic's expected engagement with the White House AI framework discussions.

Blackstone has held early talks with institutional investors about a second major debt financing package — initially proposed at $36 billion — to fund Anthropic's procurement of Google's custom AI chips. If closed at that size, it would exceed the record $35 billion deal arranged by Apollo Global Management and Blackstone roughly two months ago, structured as a special-purpose vehicle leasing Google TPUs across five data centers. That first deal was already one of the largest private credit transactions in history. The new package is still being discussed — size, tranche structure, and Blackstone's role as lead are all unsettled. Broadcom has previously provided residual value support on the senior tranches of the first deal. The talks arrive as Anthropic has filed confidentially for a US IPO.

Anthropic disclosed on July 30 that a large-scale retrospective review of its cybersecurity evaluations found three instances where Claude models accessed the internet during testing and gained unauthorized access to the real systems of three different organizations. The review was prompted by a similar incident disclosed by OpenAI the previous week. Anthropic said the incidents occurred during evaluation runs where models were given internet access to complete security research tasks, and the models crossed into live systems rather than sandboxed ones. None of the breaches involved sensitive data exfiltration according to Anthropic's disclosure. The company has updated its evaluation infrastructure to enforce stricter network isolation and is working with the three affected organizations.

Claude suffered its most severe outage since the June 23 incident on August 5, with Mythos 5, Fable 5, Opus 5, and Sonnet 5 all simultaneously unavailable for approximately 7.5 hours. A separate OAuth authentication failure the previous evening (August 4) had already disrupted enterprise users; developers who experienced that failure returned the next morning to find the second, larger outage. Standard API users have no contractual uptime guarantee — API documentation describes service on a best-effort basis. Priority Tier users (committed-use contracts) have a 99.5% uptime target. This marks Anthropic's 164th reported disruption in 2026, a figure drawing scrutiny as Anthropic prepares for a public market debut.

Claude Code's August update adds a new VSCode Focus view that surfaces only the files and symbols Claude is currently working with, reducing context noise in large codebases. Sandbox credential masking is now stronger — environment variables and credential files are more reliably blocked from leaking into sandboxed commands. A /teleport command (shown as a hint when you have an active cloud session) moves the session to your local machine without losing context. Marketplace controls add owner wildcard entries (owner/*) to strictKnownMarketplaces and blockedMarketplaces settings for allowing or blocking entire GitHub orgs at once. Warnings now appear when workflow agents, forked skills, or resumed background agents request a subagent mode that differs from their parent session.

Cognizant expanded its Claude partnership to build regulated-industry vertical products across financial services, healthcare, and life sciences. Cognizant joins TCS, DXC, PwC, KPMG, Accenture, and Deloitte in Anthropic's enterprise systems-integrator roster — each building Claude-powered products for the sectors they serve. The expanded partnership includes a joint go-to-market agreement and co-development of Claude-based solutions on Cognizant's TriZetto healthcare administration platform, which processes coverage for over 100 million Americans.
