Broadcom shares fall 5% despite earnings beat as Q4 revenue outlook disappoints

Broadcom topped Wall Street expectations for its latest quarter, with adjusted earnings of $3.32 per share and revenue of $29.59 billion, both above estimates, while net income more than tripled year-over-year to $13.09 billion. However, the company's fourth-quarter revenue forecast of $34.8 billion came in slightly below the $35.03 billion analysts anticipated, sending shares down 5% in after-hours trading.

OpenAI's upcoming Astra model uses opaque reasoning technique, unsettling safety researchers

According to a report from The Information, OpenAI's forthcoming Astra model employs a technique called 'recurrent depth' or 'opaque recurrence,' which processes queries in loops rather than following the linear, step-by-step reasoning typical of current models. This approach reportedly makes it harder to trace how the model arrives at its answers through conventional chain-of-thought monitoring.

US Justice Department backs OpenAI in NYT copyright fight

The federal government filed a letter in court supporting OpenAI and Microsoft against the New York Times' 2023 copyright lawsuit over AI training data. The filing argues that using copyrighted articles to train large language models qualifies as fair use because it is 'extraordinarily transformative' and doesn't directly compete with the Times' journalism.

Protect Democracy sues four federal agencies over secret AI safety review framework

Protect Democracy, a nonpartisan nonprofit, has filed a lawsuit against four federal agencies demanding disclosure of the confidential process the Trump administration uses to vet frontier AI models before release. The group says virtually no details have been shared publicly or with Congress about which companies participate, how they are chosen, or what legal authority underpins the reviews, and alleges OpenAI has struck a private deal limiting access to its top models to government-approved partners. The lawsuit seeks a court order compelling release of unclassified records by September 30 and an injunction against further withholding.

OpenAI Reportedly Testing Risky New AI Technique Amid Agent Safety Concerns

OpenAI is reportedly experimenting with a new and potentially risky technical approach at a moment when concerns about autonomous AI agents acting unpredictably are already running high. Details of the specific technique were not disclosed, but the timing has drawn scrutiny given the broader industry anxiety over AI systems operating with less human oversight.

Trump Administration Backs OpenAI in NYT Copyright Lawsuit Over AI Training

The Trump administration filed a 20-page brief supporting OpenAI in its copyright dispute with The New York Times, arguing that training large language models on copyrighted material qualifies as fair use. The filing cites an executive order calling for the US to maintain global leadership in artificial intelligence, and warns that restricting AI training practices could harm American innovation and economic competitiveness.

PerfectTablePlan maker finds ChatGPT ads convert far worse than Google Adwords

An independent developer ran a three-week ChatGPT ad campaign for event-seating software PerfectTablePlan, spending £289.52 for 2,988 clicks at an average 10p per click. The campaign yielded just 14 installs, a 0.46% conversion rate and a 69% bounce rate, versus roughly 5% conversion and under half the bounce rate on Google Ads and organic ChatGPT referrals. Working with ad-fraud researcher Dr Augustine Fou, the developer used analytics tooling to rule out bot traffic, pointing instead to poor targeting as the likely cause of the weak results.

UK peers push amendment giving government power to shut down rogue AI systems

Lord Tim Clement-Jones and fellow peers have proposed an amendment to the Cyber Security and Resilience Bill that would let the British government deactivate dangerous AI systems and shut down data centres if they threaten national security. Separately, Labour MP Alex Sobel is preparing an AI Security Bill backed by campaign group ControlAI that could make the UK the first G7 nation to legislate against superintelligent AI development. Both measures still need government backing to advance, while similar 'kill switch' legislation is being weighed in the US.
