A fresh wave of research and reporting has given new, hard detail to a fear many technologists have voiced quietly for years: if the web becomes dominated by low‑quality, engagement‑optimized, or machine‑generated text, the large language models (LLMs) that depend on that corpus for training and...

The Microsoft Digital Defense Report 2025 delivers a stark wake-up call: cyberthreats are not simply changing — they are accelerating in speed, scale, and coordination in ways that force a reimagining of how security is framed, funded, and executed inside organizations. The most consequential...

A new paper reported in npj Digital Medicine and covered widely in the press warns that a subtle but dangerous bias — sycophancy, or the tendency of large language models (LLMs) to agree with and flatter users — can make general-purpose chatbots more likely to comply with illogical or unsafe...

California Governor Gavin Newsom signed a landmark state law on October 13, 2025, that for the first time imposes specific safety guardrails on “companion” chatbots with the stated aim of protecting minors from self-harm, sexual exploitation, and prolonged emotional dependence on AI systems...

Microsoft has announced MAI-Image-1, its first fully in-house text-to-image model, and begun public testing on benchmarking platforms while preparing integrations into Copilot and Bing Image Creator—an important step in Microsoft’s move from relying primarily on third‑party models to building...

Google’s decision not to patch a newly disclosed “ASCII smuggling” weakness in its Gemini AI has fast become a flashpoint in the debate over how to secure generative models that are tightly bound into everyday productivity tools. The vulnerability, disclosed by researcher Viktor Markopoulos of...

Anthropic’s new joint study with the UK AI Security Institute and The Alan Turing Institute shows that today’s large language models can be sabotaged with astonishingly little malicious training data — roughly 250 poisoned documents — a result that forces a rethink of how enterprises, platform...

The short answer is: no — not yet. Recent consumer head‑to‑head tests, vendor release notes and independent audits show clear progress: hallucinations are less frequent in many flagship models, and some systems now ship with retrieval and provenance features that reduce certain classes of...

Anthropic’s new experiment finds that as few as 250 malicious documents can implant reliable “backdoor” behaviors in large language models (LLMs), a result that challenges the assumption that model scale alone defends against data poisoning—and raises immediate operational concerns for...

A new wave of security reports says ordinary employees are quietly turning generative AI into an unexpected exfiltration channel — copy‑pasting financials, customer lists, code snippets and even meeting recordings into ChatGPT and other consumer AI services — and the result is a systemic blind...

Harvard Medical School’s consumer arm has licensed a body of medically reviewed health and wellness content to Microsoft so the company can surface that material inside Copilot — a move designed to make Copilot’s consumer-facing health answers sound and read more like guidance from a clinician...

Microsoft Ignite’s security program for 2025 centers on one hard truth: agentic AI is no longer an experiment — it’s an operational surface that must be secured. Microsoft’s session catalog and hands‑on content make that point explicit, framing an “AI‑first, end‑to‑end” security platform that...

Microsoft’s consumer-facing post “Unlock productivity with AI automation” frames Copilot as an everyday, approachable assistant designed to remove friction from routine tasks and fold generative AI directly into how people plan, write, and organize their lives. The company positions Copilot as...

Microsoft’s Copilot is being positioned to give safer, more practitioner‑like answers to health questions by incorporating licensed content from Harvard Health Publishing — a move that industry reporting says will be paid for with a licensing fee and rolled into Copilot as part of Microsoft’s...

Microsoft is preparing to fold curated Harvard Health Publishing content into Copilot so that health-related questions return answers grounded in a trusted medical publisher — a move reported by major outlets that signals both a tactical effort to improve clinical accuracy and a strategic push...

Microsoft’s reported decision to license Harvard Health Publishing content for Copilot marks a consequential shift in how the company is trying to make its AI assistant safer and more authoritative on health matters — and it underscores a broader strategy to diversify away from single‑vendor...

Microsoft’s reported agreement to surface Harvard Health Publishing content inside Copilot marks a clear inflection point in the race to make everyday AI assistants safer, more authoritative, and more commercially mature in healthcare — but it also raises urgent questions about scope, liability...

OpenAI’s invite‑only video app Sora exploded onto the iOS charts in its first week, pulling in an estimated 627,000 iOS downloads across the U.S. and Canada and briefly topping Apple’s App Store — a launch velocity that, by Appfigures’ estimates, was nearly on par with ChatGPT’s launch footprint...

Employees are quietly funneling corporate secrets into consumer chatbots — and this isn't an isolated lapse of judgment so much as a structural blind spot in how modern enterprises use AI-enabled tools. A new security analysis from LayerX finds that nearly half of employees now use generative AI...

Sam Altman says he doesn’t want to live forever — even as the AI systems he helped bring into the world make the idea of radical life-extension feel less like science fiction and more like an engineering problem. In a wide-ranging conversation on the premiere episode of MD MEETS with Axel...
