OpenAI releases its first model at the critical cyber level

OpenAI released GPT-6 Astra on Thursday. Daybreak cybersecurity customers received access first. Paid ChatGPT plans and the API are due over the following week. OpenAI classified Astra at the critical cybersecurity level under its Preparedness Framework. The company says the model can find unknown flaws and build working exploit chains against hardened systems. In its internal tests, Astra used two previously unknown flaws as part of an exploit chain.

The company produced most of the capability and safety evidence. Its system card says advanced cyber access will remain restricted and that automated monitoring can pause legitimate work. TechCrunch also reported that Astra's reasoning can be harder to inspect as it uses fewer visible language tokens.

New York Fed survey points to retraining, not mass layoffs

The Federal Reserve Bank of New York's August regional surveys found AI use at 61 percent of service firms and 51 percent of manufacturers. A year earlier, the shares were 40 percent and 26 percent. Among adopters, the median share of workers using AI was 17 percent at service firms and 7 percent at manufacturers. Four percent of service firms reported AI-related layoffs over the prior six months. No manufacturers reported them.

This is a regional business survey covering New York and northern New Jersey, not a national labor count. Firms also reported quieter effects. Fifteen percent of service firms hired fewer workers because of AI, while 13 percent hired more workers to support it.

Pentagon says its Anthropic ban still stands

Under Secretary of Defense Emil Michael said Thursday that Anthropic remains a supply-chain risk for the Defense Department and its industrial base. The statement came one day after Commerce Secretary Howard Lutnick said the administration trusted Anthropic again. It also followed an August 27 federal ruling that found the Pentagon had illegally punished Anthropic and set aside the designation.

The Defense Department did not explain how its statement fits the court order. It also did not answer Reuters's request for comment. The public record now has conflicting positions from two cabinet departments and a federal court. Commerce's warmer stance toward Anthropic does not settle the separate Pentagon dispute.

G20 ministers back a lighter rulebook for AI

G20 innovation ministers adopted the Carolina Principles after a two-day meeting in Chapel Hill, North Carolina. The consensus calls for governments to use existing sector rules where they fit. It reserves new regulation for issues those rules cannot address. It also calls for research funding, faster commercialization, AI use in public services and workforce training.

The statement preserves each member's national authority and creates no binding enforcement system. The United States hosted the meeting and built the approach around flexible regulation. Agreement on principles does not mean China, the European Union and the United States will apply the same rules.

Crusoe triples its valuation on a $3 billion raise

Bloomberg reported that AI infrastructure company Crusoe raised more than $3 billion at a valuation near $30 billion. TechCrunch and Reuters carried Bloomberg's report. The new value is three times the $10 billion valuation from Crusoe's October 2025 round. Bloomberg also reported a five-year cloud contract worth about $13 billion to provide Jane Street with computing clusters for AI training and use.

Crusoe and Jane Street did not confirm the contract to Reuters. The funding and contract figures come from people familiar with private deals, not public filings. A large contract value also says little about the money, power and construction Crusoe needs to serve it.

AI scribes can miss what patients mean

A University of Edinburgh team reviewed 27 studies and reports on ambient AI scribes in health care. The review found that automated notes can reduce paperwork and capture clinical facts. It also found risks that summaries miss facial expressions, gestures, emotion and the way patients describe illness. Patients can also hold back sensitive information when they know a system records and processes the visit.

This is a review of a young body of evidence, not a clinical trial proving harm. The researchers say most studies focus on short-term productivity. They found less evidence about patient trust, clinician memory, skill development and use across different health systems.
