Ilya Sutskever Stands by His Role in Sam Altman's OpenAI Ouster: 'I Didn't Want It to Be Destroyed' The former OpenAI chief scientist may be estranged from the company, but he still came to its defense as he testified on Monday. Elon Musk's trial against OpenAI and Microsoft entered its final stretch on Monday, with testimony from Microsoft CEO Satya Nadella, former OpenAI chief scientist Ilya Sutskever, and current OpenAI chairman Bret Taylor. Sutskever drew the spotlight, revealing an ownership stake in OpenAI's $850-billion for-profit arm that is currently worth about $7 billion. That makes him one of the largest known individual shareholders of OpenAI. Earlier in the trial, OpenAI president Greg Brockman acknowledged for the first time that he has around $30 billion worth of OpenAI shares .

Leaders at the tech giant were skeptical of OpenAI--but wary of pushing it into the arms of Amazon, according to evidence revealed during the trial. OpenAI's relationship with Microsoft, its longtime investor and cloud partner, has grown increasingly complicated over the years as the ChatGPT-maker has grown into a behemoth competitor . But Microsoft executives had reservations about sending additional funding to OpenAI as far back as 2018 when it was just a small nonprofit research lab, according to emails between more than a dozen Microsoft executives, including CEO Satya Nadella, shown in a federal court on Thursday during the trial. The emails show how Microsoft, at the time, wavered over what has since been held up as one of the most successful corporate partnerships in tech history. Several Microsoft executives said in the emails their visits to OpenAI did not indicate any imminent breakthroughs in developing artificial general intelligence.

Xbox is ditching Microsoft's Copilot AI Xbox is ditching Microsoft's Copilot AI Microsoft announced plans to start stripping Copilot out of select Windows apps in March after criticism of the company's mishandling of its operating system reached a fever pitch. As it turns out though, Windows isn't the only place where you'll see less Copilot: Xbox CEO Asha Sharma has announced that the AI assistant will also be removed from the gaming brand's mobile app and Xbox consoles. Under previous Xbox leadership, Copilot was introduced as a sort of in-game assistant that would be aware of what you're playing and able to offer contextual advice based on what's on your screen. Microsoft launched a beta version of the experience by adding Copilot to the Xbox mobile app in May 2025, but based on a GDC presentation the company gave in March, the plan was to also bring Copilot to Xbox consoles later this year. Those plans apparently don't align with where Xbox is headed, Sharma said in a post announcing new hires to the Xbox division.

New artificial intelligence (AI) tools and capabilities from Google, Microsoft and xAI will now be tested by the US Department of Commerce before they are released to the public. The tech firms have agreed to voluntarily submit their models for testing through Commerce's Center for AI Standards and Innovation (CAISI). The new pacts are an expansion on agreements by AI companies like OpenAI and Anthropic that were reached during the Biden Administration, and will see AI models from all of the companies evaluated for their capabilities and security. These expanded industry collaborations help us scale our work in the public interest at a critical moment, CAISI's director Chris Fall said. Overall, the evaluations of the AI tools will cover testing, collaborative research and best practice development related to commercial AI systems.

Tech giants Microsoft, Google and xAI say they will allow the United States federal government access to their new artificial intelligence models for national security testing. The Center for AI Standards and Innovation (CAISI) at the Department of Commerce announced the agreement on Tuesday amid increasing concerns about the capabilities that Anthropic's newly unveiled Mythos model could give hackers. The agreement fulfils a pledge the administration of US President Donald Trump made in July to partner with technology companies to vet their AI models for "national security risks". Microsoft will work with US government scientists to test AI systems "in ways that probe unexpected behaviors", the company said in a statement. Together they will develop shared data sets and workflows for testing the company's models, the company said.

PCWorld tested Microsoft's Auto SR, a DLSS rival exclusive to the Asus ROG Ally X, finding it delivers only marginal 10% performance gains in games like Borderlands 3. The technology currently works only in docked mode at 720p resolution and produces notably degraded visuals described as'muddy' and'swimmy' compared to native resolution. Auto SR remains in Preview status with significant usability issues including incorrect scaling and required game restarts, making it inadequate for handheld gaming improvement. Last week Microsoft announced the arrival of Auto SR, its Windows-branded alternative to upscaling tech like DLSS, with great fanfare. After being semi-exclusive to Snapdragon laptops, it came to the Asus ROG Xbox Ally X and nothing else. Not even the non-X variant, since it needs an NPU to run. And also it only works in docked mode, not handheld mode.

PCWorld outlines five essential Windows Defender configuration changes to optimize security and performance on new Windows PCs. Key adjustments include disabling redundant system tray icons, turning off unnecessary "no threats found" notifications, and enabling Controlled Folder Access for ransomware protection. Strategic exclusions for trusted files and adjusting Core Isolation settings can improve performance while maintaining robust built-in antivirus protection. Windows Defender is a capable antivirus solution built into Windows itself. Unless you've installed a different antivirus program on your Windows 11 or Windows 10 PC, your PC is using it right now.

PCWorld reports that Microsoft is overhauling Windows 11 with significant performance improvements targeting File Explorer, Start menu, and system responsiveness through better CPU scheduling and memory management. The updates separate Widgets from the Discover feed and adopt a "calm" approach with fewer notifications, though concerns arise about AI-summarized content potentially harming creators. These changes aim to make Windows 11 "feel faster" and more competitive with macOS, rolling out through the Windows Insider program. This is the new, more productive Windows 11. On Friday, Microsoft said that it has begun making improvements to File Explorer, speeding up Windows under the hood, and minimizing distractions from the Windows widgets, all in the name of getting more done. Microsoft's moves underscore what it began talking about in March: emphasizing a cleaner, more efficient Windows while scaling back on Copilot and moving toward adding features that customers have demanded, such as a configurable taskbar .

In this episode of “Uncanny Valley,” we get into how the Elon Musk-Sam Altman trial goes way beyond their rivalry and could have major implications both for OpenAI and also the AI industry at large.

PCWorld reports on Microsoft's Auto SR, an AI-enhanced upscaling technology that provides significant performance boosts for gaming handhelds like the Asus ROG Xbox Ally X. Early testing demonstrates impressive results, with Auto SR delivering up to 50% framerate improvements in games like Borderlands 3 by leveraging integrated NPU chips. Currently available through Windows Insider builds with 11 supported games, this OS-level tool represents Microsoft's answer to Nvidia DLSS and AMD FSR for low-power gaming systems. The Asus ROG Xbox Ally is more powerful than the aging Steam Deck, even if you go for the cheaper, non-X variant. But it's still based on an AMD laptop chip with integrated graphics.
