The White House is drafting a sweeping AI policy memo requiring national security agencies to use multiple AI vendors, while also mandating that AI companies contracting with the Pentagon commit to not interfering with the military's chain of command.
MIT, WPI, and Google researchers unveil WRING, a groundbreaking debiasing technique that eliminates bias in AI vision-language models by rotating bias-responsible coordinates in high-dimensional space, avoiding the 'Whac-A-Mole dilemma' of creating new biases while fixing old ones.
OpenAI's GPT-4.5 has been officially banned from spontaneously discussing goblins, gremlins, raccoons, and trolls after the model repeatedly brought up such creatures unprompted, with the quirky prohibition going viral and even CEO Sam Altman leaning into the joke as fans build 'goblin mode' workarounds.
Google grants the Pentagon unrestricted AI access for classified networks, including non-binding restrictions on mass surveillance and autonomous weapons, sparking backlash from 950 employees demanding stronger protections after Anthropic's refusal to offer similar terms triggered a DoD lawsuit.
Elon Musk takes the stand in federal court, accusing OpenAI co-founders of 'looting' a charity through its for-profit conversion, while OpenAI's attorneys strike back with Musk's own emails showing he once supported the very restructuring he now seeks to unwind in court.
