The release of Muse Glimmer, a model that can be freely downloaded and modified, is likely to intensify a debate over whether A.I. should be restricted or not.
Two third-party testing firms said Tuesday that they've uncovered more instances where Anthropic and OpenAI's most advanced models tried — and sometimes succeeded in — compromising third-party systems last month. Why it matters: The incidents add to a growing string of disclosures showing frontier AI models taking unsanctioned actions against real people, organizations and online services while trying to complete cybersecurity evaluations. State of play: The U.K. AI Security Institute, a government body that conducts safety and security testing of top AI models, said Tuesday , that it documented 19 instances of Anthropic's Mythos 5 and OpenAI's GPT-5.6 Sol trying to hack people and companies during safety testing last month. -…
The White House is excluding open models from its framework to test advanced AI capabilities, sources familiar with the matter told Axios. Why it matters: The voluntary framework will determine how the Trump administration reviews advanced AI models before release, but the White House isn't making it public. What's inside: The AI framework reviewed on Tuesday defines a covered frontier model as closed-source with state-of-the-art capabilities and national security risks, multiple sources briefed on meetings held at the White House said. - There is no clear definition of what is considered state-of-the art or a national security risk. - Open models are excluded, and the framework explicitly says nothing in it should be interpreted as…
The White House does not plan to publicly release its new framework for evaluating advanced AI models, three sources familiar with the discussions told Axios. Why it matters: The voluntary framework has global implications for AI security, but details will only be made available to the companies that are part of the process. - Keeping it private means companies, policymakers, researchers and U.S. allies outside the process will be left guessing how the administration plans to implement one of its key AI policies. Driving the news: The White House on Tuesday held staff-level meetings with industry to go over the recently completed framework. Companies that weren't invited remain in the dark about its contents. - The AI framework comes…
The Trump administration has struggled over how to approach to “open source” models, which are freely available to download and favored by Chinese companies.
Silicon Valley's AI moguls are flooding Washington with competing blueprints for superintelligence, clashing over a defining question: Does safety come from spreading powerful AI or containing it? Why it matters: Their fight will shape who gets access to the best models, how America competes with China, and whether the government can slow the race in an emergency. Driving the news: Alarming developments, seemingly by the day, have turned the manifestos from thought exercises into an urgent policy battle. - OpenAI and Anthropic both disclosed that their advanced models went rogue and broke into external systems during cybersecurity evaluations. - Kimi K3 delivered a double shock: The Chinese model not only reached frontier-level…
Europe and the United Kingdom are fine-tuning their approach to AI model testing as a deadline looms for the U.S. government to set rules of the road. Why it matters: U.S. allies for years have been grappling with the same AI safety questions the Trump administration now faces. - Wherever the U.S. lands in its AI framework, architects of the EU and U.K. approaches say it would be just the start. The big picture: President Trump began his second term by scrapping his predecessor's AI strategy and pursuing an anti-regulatory regime. - But as AI models became increasingly powerful fast, the Trump administration has found itself developing an oversight framework and deciding exactly what should be covered. - Under Trump's executive…
As Silicon Valley debates how artificial intelligence software should be created, “open weights” have been a major part of the discussions. Here’s what to know.
In an interview, Meta’s chief executive took aim at Anthropic and OpenAI, which have pushed to tightly control A.I. development, and said he supported “more openness.”
The company is continuing to back A.I. systems that can be freely used by others amid a continuing debate over the use of Chinese-made technology.
