    Today, with over 100 industry partners, we introduced the NVIDIA Open Agent Safety Platform, bringing together OpenShell and Sentry. Artificial intelligence is extraordinary technology that will advance discovery, productivity, security, health, and prosperity for generations to come. But its full promise can only be realized when people have confidence that AI is being built to be safe and deployed with wisdom and responsibility. This is bigger than a single product. It's the beginning of an open ecosystem to build the trust layer for safe agent systems. Together, we are building the foundation of the AI economy. Trust and innovation are not in conflict. Safety is how trust is earned. We must build not only the most capable AI, but the most trusted AI, so that this extraordinary technology can realize its enormous promise for the world. https://nvda.ws/4hcoq7m

    Nvidia leads a broad industry coalition to establish open standards for AI safety, creating a shared foundation for autonomous agent systems.

    🦔The Blue Cross Blue Shield Association says insurers paid out nearly $1 billion more than usual from AI-assisted hospital documentation in 2024-2025. Hospitals use AI to scan records and find secondary diagnoses that human reviewers missed. More diagnoses means higher reimbursements. But treatment levels haven't gone up. BCBSA's SVP of data science said AI is "identifying more billable conditions, not sicker patients." Insurers now deploy their own AI to deny those same claims. Patients pay for both through higher premiums. My Take This might be the most American healthcare story I've ever read. Hospitals bought AI to find more things to bill for. Insurers bought AI to deny those bills. The technology cost money on each end and the tab went straight to patients through higher premiums. A billion dollars moved and no one got any healthier. The only thing that changed was the size of the invoices. Two sides of a trillion-dollar industry found a new tool to fight over the same pool of money and the person in the hospital bed pays for all of it. Premiums go up, denials go up, and the AI vendors collect from everyone. If you want to know who AI works for, stop reading the press releases and look at where the money goes. In healthcare it went straight into the billing department. Hedgie🤗

    AI is optimizing medical billing rather than patient outcomes, triggering an automated arms race between hospitals and insurance providers.

    I want to thank Andrew Bailey for his dedicated service to return the FBI to its core mission and fulfill President Trump's promise to make America safe again. Although Andrew is leaving the FBI in order to return to his family in Missouri, his fantastic contribution instituting critical reforms which resulted in our historic success will live on. Andrew's leadership at the FBI will be missed but we are grateful he answered the call to serve! Thanks Andrew for your tremendous dedication to the mission of this FBI.

    CHINA 🇨🇳 WEIGHS EASING RESTRICTIONS ON NEW $NVDA CHIP PURCHASES Beijing has signaled it may allow Alibaba, ByteDance and others to buy Nvidia’s new RTX Pro 5500, per The Information. ByteDance alone is weighing an order for about 1M chips. Key details: • Nvidia plans to begin shipments in late December • Targeting ~500K chips per quarter for China • ByteDance’s potential order alone could take 2 quarters to fill • Buyers plan to put 8 chips per server to run AI models • Price: ~85K-90K yuan, roughly $13K each • Similar pricing to Huawei’s Ascend 950PR The RTX Pro 5500 is not one of Nvidia’s top data-center AI chips and lacks the high-speed interconnects and premium memory used in those systems. The bigger story is China’s compute shortage. AI companies are rolling out products faster than domestic chip supply can keep up, with Huawei itself recently saying it cannot meet demand. Approval timing, quantities and conditions are still unclear.

    Beijing signals a potential thaw in technology trade restrictions, opening a massive market for Nvidia's latest enterprise AI hardware.
