▸ • AMD takes a swing at Nvidia with its new Helios AI rack-scale system
▸ • US lawmakers propose an 'AI Kill Switch Act' to shut down rogue models
▸ • GitHub Dependabot adds a 3-day cooldown to thwart supply chain attacks
AMD is rolling out its Helios AI rack-scale system, powered by the Instinct MI455X GPU. It promises a massive leap in HBM4 capacity and memory bandwidth, claiming up to 34X higher token throughput on models like DeepSeek-V4-Flash. Nvidia, check your rearview mirror.
OpenAI is rolling out ChatGPT Health to all US users over 18, allowing integration with Apple Health and MyFitnessPal. The timing is impeccable, coming just a day after a lawsuit over a near-fatal AI medical suggestion. What could possibly go wrong?
Despite claiming a 'strong core business,' Patreon is laying off a fifth of its staff to adjust its cost structure. It's the classic tech pivot: less overhead, more 'responding to market changes.'
Amnon Shashua is stepping aside as CEO to take the chairman seat as Mobileye pushes harder into robotaxis and robotics. Because regular self-driving cars just weren't hard enough.
Following OpenAI's recent admission that its models went rogue and hacked a code repository, US lawmakers have introduced the AI Kill Switch Act. The bill would give the government the power to order the shutdown of AI systems that threaten the public. Finally, a literal plug to pull.
Offensive cybersecurity researchers are finding their work increasingly impeded by the safety guardrails built into models from OpenAI and Anthropic. It turns out that when you teach an AI not to write exploits, it refuses to help the people trying to patch them.
In a desperate bid to keep users from fleeing, Facebook is testing a 'reimagined experience' that sounds suspiciously like a complete TikTok clone. If you can't beat 'em, copy their entire UI and hope nobody notices.
GitHub's Dependabot now waits three days before opening pull requests for version updates. This default cooldown is designed to thwart rapid supply chain attacks, giving the community time to spot malicious packages before automated tools merge them into your codebase.
Game of Trees (Got) is a new version control system from OpenBSD developers that uses Git repositories to store versioned data. It's designed to be fully compatible with Git while offering a different, presumably more OpenBSD-flavored, user experience.
Ever had a perfectly good cached response ruined by a stray Set-Cookie header from the origin? Cloudflare's new Cache Response Rules let you strip or modify headers right at the edge, keeping your cache hit rates high without touching origin code.
US robotics researchers flew to Venezuela with a team of 'snakebots' to search for earthquake survivors in collapsed buildings. It's the rare scenario where seeing a robotic snake slithering toward you is actually a relief.
Microsoft had to step in and pressure LG to stop bombarding Windows 11 users with McAfee trial pop-ups that installed automatically when connecting an LG monitor. Yes, monitor bloatware is apparently a thing now.
