MedAgentBench: Stanford’s New Benchmark for Healthcare AI

When it comes to AI in healthcare, the stakes are high—lives, not just likes, are on the line. That’s why Stanford’s release of MedAgentBench this week is such a big deal. Unlike previous benchmarks that tested AI on simple Q&A or text-based tasks, MedAgentBench throws AI agents into the deep end: realistic, tool-based Electronic Health Record (EHR) environments.

What makes MedAgentBench different?

• It features 300 clinician-written tasks across 10 categories, from test ordering to medication management and documentation.
• The benchmark uses 100 de-identified patient profiles drawn from over 700,000 real-world records, ensuring the scenarios are as authentic as possible.
• It operates via a FHIR-compliant interface, meaning AI agents must actually retrieve and modify EHR data—just like a real doctor’s assistant would.

When tested, 12 major large language models (LLMs)—including Claude 3.5 Sonnet v2 and GPT-4o—showed impressive data retrieval skills but struggled with safely executing complex actions. The top performer, Claude 3.5 Sonnet v2, achieved a 69.7% success rate, highlighting both the promise and the current limitations of AI in clinical settings.

Why does this matter?
As Dr. Eric Topol, a leading digital health expert, put it, “Benchmarks like MedAgentBench are crucial for moving from hype to real-world impact. They help us see where AI is ready—and where it still needs a human in the loop.” For patients in rural or underserved areas, smarter AI assistants could mean faster, safer care. For clinicians, it’s a step toward reducing burnout and administrative overload.

Apple Intelligence: Smarter Devices, Seamless Experiences

If you own an iPhone, iPad, or Mac, you’ve probably noticed your device getting a little…smarter. That’s no accident. In late September, Apple rolled out a suite of AI-powered features that blend generative intelligence with everyday usability[1].

What’s new in Apple Intelligence?

• Live Translation in Messages, FaceTime, and phone calls, powered by on-device AI.
• Enhanced Genmoji creation, letting users combine emojis with AI-generated suggestions.
• Visual Intelligence upgrades, including screenshot support and smarter image editing.
• Expanded language support for Chinese (Traditional), Danish, Dutch, Norwegian, Portuguese (Portugal), Swedish, and Turkish.
• Developers can now access Apple Intelligence's on-device foundation model to create private, intelligent experiences within their apps[1].

Apple’s September update (iOS 26/iPadOS 26/macOS Tahoe 26) reflects a broader strategy: make AI so seamless, you barely notice it’s there—until you can’t live without it[1].

Why does this matter?
By controlling all core iPhone chips and prioritizing AI workloads, Apple is betting that the next wave of device innovation will be powered by intelligence, not just speed or screen size. For users, this means more intuitive interactions, smarter automation, and features that adapt to your needs in real time.

Google’s AI-Powered Search Goes Global

While Apple is making your phone smarter, Google is aiming to make the world’s information more accessible—and conversational. In September, Google expanded its AI-powered search features to over 180 new countries and territories, bringing its Gemini-powered “AI Mode” to a truly global audience.

Key features in Google’s AI search expansion:

• AI Overviews: Summarized answers with source citations, now available in the U.S. and rolling out globally.
