OpenAI Launches ChatGPT Health, Gmail Gets Smarter, and AI Starts Predicting Disease

FEATURED INSIGHT💡

ChatGPT Health is a new kind of “space” inside ChatGPT

OpenAI introduced ChatGPT Health, a dedicated experience inside ChatGPT built specifically for health and wellness. The big shift is that it’s not just answering health questions, it’s designed to securely combine your health context with the model, so the conversation can be grounded in your own records and tracking.

Health runs as a separate compartment with additional protections, separate memories, and strong boundaries between health and non-health chats. You can connect medical records and wellness apps (availability varies by region), and OpenAI says Health conversations are not used to train foundation models. The rollout starts with a small group, with broader web and iOS availability planned soon.

Gmail is turning into an inbox you can question, not just search

Google says Gmail is entering the Gemini era, with new features that treat your inbox like a knowledge source instead of a pile of threads. The headline is AI Overviews: Gmail can summarize messy email chains into a clean set of key points, and it can also answer questions you ask about your inbox in natural language.

Google is also testing an “AI Inbox” concept that highlights what’s important and pulls out to-dos, with personalization signals like frequent contacts and inferred relationships. This is one of the clearest examples yet of productivity tools shifting from “find and read” to “ask and act.”

Stanford publishes the first large-scale sleep foundation model for disease prediction

Researchers at Stanford released SleepFM, a multimodal foundation model trained on over half a million hours of polysomnography data. From a single night of sleep, the model can predict future disease risk across more than 100 conditions and generalizes well to external datasets.

SleepFM uses self-supervised contrastive learning and a channel-agnostic architecture to handle heterogeneous sleep recordings, showing how foundation models can extract long-term health signals from raw physiological data.
