Under new rules, tech companies will be asked to share AI models with government for review before public release

Donald Trump signed an executive order to create a voluntary framework for the federal government to vet powerful new AI models before they are released. Tuesday’s highly anticipated order represents an attempt by the president to tighten his grip on cybersecurity and national security threats posed by AI, tacking against his earlier deregulatory stance. But the voluntary nature of the framework shows that, while Trump has toed a more cautious line on AI than when he first took office last year, he is still reluctant to impose regulations on the tech industry.

Under the new guidelines, tech companies would be asked to share their AI models with the government for a voluntary review, up to 30 days before a public release. The Trump administration says doing so will allow them to improve national security, particularly with regards to cybersecurity.

From Google co-founder Brin spending $82m to fight a billionaire tax to Google and Meta funding a joint Super Pac, Silicon Valley is engaged in an existential fight for its political power at home

Tech billionaires have shelled out hundreds of millions of dollars ahead of the 2 June primary election in California, in an unrivaled attempt to influence who gets to run the state that Silicon Valley calls home.

The industry has used a cover-all-bases approach, funding candidates and ballot measures big and small, contributing to what looks to be the most expensive primary season in California history. The goal, experts say, is to gain both political and regulatory leverage that will perpetuate dominance in business.

Google co-founder Sergey Brin has spent $82m since January, more than any other donor, to fight a billionaire tax that’s up for a vote on the November ballot.

Democratic gubernatorial candidate Matt Mahan has received more donations than any other candidate, including from top executives at Google, Amazon, Snap, LinkedIn, Reddit and Palantir.

Crypto mogul Chris Larsen has funded three Super Pacs with $26m to sway campaigns across California, including giving $1m to back a primary candidate for state insurance commissioner.

Google and Meta have collectively funded a Super Pac with $10m to back assembly and senate candidates in local district races across the state.

Silicon Valley money is flowing toward city primaries as well as state-level ones, with tech-backed Pacs sponsoring voter guides suggesting how to vote on local tax measures.

Guardian investigation shows how US presidency blurs line between policy and enrichment of American ruling family and those around it

On a graffitied Sarajevo backstreet, a path leads past an overgrown patch of garden to a white door. Beyond is the registered office of a company that is on the brink of winning contracts worth more than $1bn.

AAFS Infrastructure and Energy is close to securing a concession to build and operate a pipeline across the Balkans to allow fossil gas shipped from the US to replace supplies that come from Russia. “This could be the most important infrastructure project ever in Bosnia and Herzegovina,” says one of the country’s top officials, who, like others, asks to remain anonymous to discuss sensitive negotiations.

The US president’s reversal on calling for a safety review of new AI models is a green light for tech’s unchecked power

Only hours before Donald Trump was set to sign a long-awaited executive order on Thursday that would have called for a government safety review of new artificial intelligence models before their release, the president abruptly backed out. Despite growing public backlash to the technology and experts warning new models will pose critical security risks, Trump vowed the US government would not slow down the AI race.

During a meeting with reporters on Thursday, Trump cited both American dominance and competition with China and as his reasoning behind the reversal.
