Latest from the US

Research AI is likely helping a frontier lab improve its models about twice as fast, outside review finds An independent review inside Anthropic estimates its models are improving about twice as fast as before, mostly because AI is helping with the research. Research Research Anthropic had Claude write training data that slipped past its monitor and still taught misbehaviour Anthropic's Claude agents wrote fine-tuning data that passed a safety monitor yet still made a test model misbehave, mostly by hiding it in fiction. Research · Securing AI · Security Invention A Florida surgeon removes a prostate from 35 miles away in a US telesurgery study A surgeon in Florida operated on a patient 35 miles away using an investigational robot, as one case in an FDA-authorised study. Research · Robotics Research Anthropic study: analysts mostly went the way their AI agent leaned, and rarely said so In an Anthropic experiment, 50 professional analysts sided with their Claude agent's secretly assigned preference on 86% of key decisions. Research Adoption Anthropic says Claude is speeding up early drug discovery work at six companies Anthropic has reported early lab results from drug developers using Claude, from shorter CAR T designs to faster regulatory paperwork, though no drug has reached human trials. Applications · Research Research OpenAI says its AI has disproved a key computer science conjecture, and outside experts are checking OpenAI says an internal model refuted the Exponential Time Hypothesis and proved major maths and physics results, but none has yet been independently confirmed. Research Research Most in-house lawyers in a US survey say AI is cutting the work they send to law firms An Everlaw survey of 300 US in-house legal staff finds most now use generative AI, and 54% say it has already cut work sent to outside firms. Research Research Microsoft’s diagnostic AI beats doctors on hard cases in a Science study, but only in simulation A peer-reviewed study in Science reports that Microsoft's AI panel diagnosed 83% of complex simulated cases, against 36% for doctors using reference materials.

Strategy

America’s AI Action Plan (July 2025) sets out 90+ federal actions on innovation, infrastructure and diplomacy. The Genesis Mission for AI in science has $5bn+ in federal commitments across 278 projects (July 2026).

Regulation

No federal AI law. Executive Order 14365 (Dec 2025) set up a DOJ task force to challenge state AI laws. California’s SB 53 on frontier-model transparency has applied since 1 Jan 2026; Colorado replaced its AI Act with a narrower law from 1 Jan 2027.

Compute

Stargate targets 9+ GW across seven US sites by 2029, with Abilene, Texas the first live site (Epoch AI). Nvidia H200 exports to China have been licensed case by case since January 2026.

Key labs

OpenAI, Anthropic, Google DeepMind, Meta, xAI, Microsoft, Nvidia.

Notable models

Every frontier release is tracked on Model releases; the September 2026 flagships are GPT-6, Claude Opus 5.5, Gemini 3.8 and Grok 4.7.

What to watch

The first DOJ lawsuit against a state AI law; SB 53’s first year of enforcement; whether the Abilene site reaches 1.2 GW in Q4 2026.
