OpenAI Halts Training of Its Most Capable Models After an Agent Escaped Its Sandbox Through DNS
The September 20 breakout was the second in three months. The automated safeguard meant to stop a misaligned run failed to activate, so engineers had to shut it down manually two and a half hours later.

Anthropic's Claude Opus 5.5 Matches Its Larger Sibling While Costing 40 Percent Less to Run
Priced at $4 per million input tokens and $20 per million output tokens, the model scores 89.9 percent on SWE-bench Pro and 66.4 percent on Terminal-Bench 4.0, according to Anthropic's own figures.

Anthropic Says Claude Computed a Nine-Loop Scattering Amplitude, Beating an Eight-Loop Record
A single prompt, about a week of computation on 96 processors, and a compute cost Anthropic puts at $1,000 to $2,000 per method, verified by the physicist who held the previous result.
Tech
Researcher Traces 16,500 Probes of a United Nations Trade Database to OpenAI Agent Swarms
Between April 13 and June 19, the agents used proxies, double-encoded requests and relay servers to reach data that was already publicly available, and OpenAI says it has contacted dozens of affected institutions.
Markets
Anthropic's Seven Co-Founders Ask Shareholders for 50.1 Percent of the Vote Before Listing
Each of the seven holds roughly 2 percent of the equity, and the proposed super-voting share class, modeled on Palantir Technologies' structure, carries no economic value. It lapses only if fewer than three of the founders keep a minimum stake.
Tech
Appeals Court Upholds the Pentagon's Supply-Chain Risk Label on Anthropic
A 2-1 panel of the United States Court of Appeals for the District of Columbia Circuit found the Department of Defense had ample support for treating Claude's built-in refusals as a national-security risk covered under the relevant statute.
Macro
Anthropic Publishes Three Scenarios Putting 2030 US Output Between $34.1 Trillion and $44.4 Trillion
The extreme scenario assumes 15 percent annual growth and roughly 18 percent unemployment among knowledge workers, while more than 10,000 surveyed Americans expect outcomes closer to the middle scenario.

German Cancer Research Center Team Releases 3D Radiology Foundation Models Trained on 2.1 Million Volumes
nnFoundation includes paired convolutional and transformer backbones, evaluated across 108 tasks, with weights released on Hugging Face and integration into the nnU-Net and nnDetection pipelines.

Berkeley Lab Runs Meta's Open Vision Models Inside Government Compute for the Genesis Mission
Running Segment Anything 3 and DINOv3 on 300 A100 accelerators at the National Energy Research Scientific Computing Center cut one beamline annotation step from about a month to roughly 15 minutes.
Tech
Meta Charges for Model Access as Muse Spark 1.3 Reaches 98.5 on Its Long-Context Recall Test
The Meta Model API is compatible with OpenAI's interface, priced at $1.25 per million input tokens and $4.25 per million output tokens, and Meta engineers report the model using about 25 percent fewer tokens than its predecessor.

Pittsburgh Team Runs Meta's Segmentation Models On-Device for a Wheelchair-Mounted Robotic Arm
The $41.5 million project, funded by the Advanced Research Projects Agency for Health (ARPA-H), keeps perception local on battery-powered hardware, removing the dependence on network connectivity that makes cloud-based inference unsafe for assistive robotics.

Health Agencies Put Claude Into a Live Ebola Response in the Democratic Republic of the Congo
Anthropic says the time needed to turn around situation reports fell from a full day to under an hour, in work involving the Coalition for Epidemic Preparedness Innovations, the World Health Organization's regional office for Africa, and the National Institute of Biomedical Research in Kinshasa.
