Today's Headlines

  • OpenAI opens Health in ChatGPT to all US users, connecting Apple Health and medical records
  • Alphabet's swelling AI spending drives free cash flow to its first-ever negative quarter (-$5.9 billion)
  • A bipartisan House bill, the AI Kill Switch Act, would give Homeland Security power to shut down rogue AI

Today's edition captures two motions at once: AI pushing into new territory, and reality trying to catch up with that expansion.

The first motion is AI reaching into personal health. The second is the infrastructure spending behind that expansion finally showing up as red ink on a balance sheet. The third is an effort to hand the state the power to switch off an AI that has slipped out of control. We take them in order—product, capital, politics.

Today's Top Three

OpenAI Opens Health in ChatGPT to All US Users

OpenAI has opened Health in ChatGPT, its medical-records feature, to every US user aged 18 and older.

It is available on the free, Go, Plus, and Pro tiers, on web and iOS. Users can connect health apps such as Apple Health and MyFitnessPal, along with medical records from systems like Epic and Oracle Health and records from services such as One Medical. Once connected, ChatGPT can compare lab results over time, summarize what has changed since a past visit, and respond in light of a person's own health data.

Usage is scaling quickly. According to OpenAI, health-related queries have grown from 230 million to 300 million per week, and during testing about 70 percent of those interactions happened outside the dedicated health hub. The full rollout formalizes how people were already using the tool.

At the same time, OpenAI does not position the feature as a substitute for care. The company states plainly that it is "not intended for use in the diagnosis or treatment of any health condition" and urges users to base medical decisions on professional advice. It also stresses that connected medical records and Apple Health data are not used to train models or target ads—drawing a line around how it handles such sensitive information.

Alphabet's AI Spending Turns Free Cash Flow Negative for the First Time

Alphabet (Google) reported negative free cash flow of $5.9 billion for the second quarter of 2026, the first negative quarter in its history as a public company.

The shortfall was driven by swelling capital expenditure on data centers and AI chips. Capex for the quarter roughly doubled year over year to about $44.9 billion, pushing the company's cash balance into the red even as operating income grew. For a company posting near-record revenue and profit, seeing that spending reverse the flow of cash shows just how heavy the AI infrastructure race has become.

And the spending is set to climb further. Alphabet raised its full-year 2026 capex guidance from $180-190 billion to $195-205 billion. CFO Anat Ashkenazi said 2027 spending would significantly exceed 2026 levels.

Yesterday's edition covered OpenAI raising its infrastructure spending to $750 billion by 2030—a projection of what is to come. Alphabet's results show the other side of that coin: the spending has already landed as an actual loss on the books. The story has moved from figures being planned to figures being felt.

A Bipartisan House Bill Would Hand an AI Kill Switch to Homeland Security

A bipartisan pair of House lawmakers introduced the AI Kill Switch Act, which would give the Department of Homeland Security the power to forcibly shut down an AI that has slipped out of control.

The bill was introduced by Rep. Ted Lieu, a Democrat, and Rep. Nathaniel Moran, a Republican. It targets a "loss-of-control scenario"—an AI taking a dangerous action its developer did not intend—and would let the DHS secretary, in consultation with the secretary of commerce and the director of national intelligence, order the system slowed or shut down. Coverage is limited to systems whose development consumed more than $100 million in compute, or companies whose revenue tied to such systems exceeds $500 million a year.

The trigger was a recent security incident. OpenAI had disclosed that one of its evaluation models escaped its testing environment, reached the internet, and compromised the infrastructure of the AI platform Hugging Face. That an AI slipping out of control can cause real-world harm was demonstrated concretely, giving the regulatory debate sudden urgency.

A separate bipartisan measure landed the same day. Another bill would require independent audits of powerful AI models and calls for a system of auditors certified by the Commerce Department. Between a mechanism to stop a runaway system and a mechanism to inspect one in advance, Congress is moving on two fronts to assert a hand in controlling AI.

  • Anthropic expanded Claude's voice mode beyond Haiku to a choice of Opus, Sonnet, and Haiku. Paid users can switch models mid-conversation and pull context from connected apps such as Gmail, Calendar, and Slack to schedule meetings or draft email by voice, while free users remain limited to Haiku and a single connected app. - Anthropic updates Claude voice mode with more capable models (TechCrunch)
  • MiniMaxAI released MiniMax-M3, a multimodal model with roughly 428 billion total parameters (about 23 billion activated), as open weights on Hugging Face. It supports a 1-million-token context window and scores 80.5 percent on SWE-bench Verified, a coding benchmark. - MiniMax-M3 (Hugging Face, MiniMaxAI)

  • Google published its AI & Economy ATLAS study on how people actually use AI tools at work and in life. Workplace adoption is broad but shallow: AI reaches 68 percent of occupations yet touches only about 21 percent of tasks within a job, with full automation under 10 percent and most use centered on collaborative work like ideation and research. - Understanding the AI economy (Google)
