Google Research Introduces GlucoFM: A 0.72M-Parameter Dual-Stream Foundation Model for Continuous Glucose Monitoring
Google Research and UNSW Sydney have released GlucoFM, a self-supervised foundation model for continuous glucose monitoring. Its core move is a split. Existing CGM models — CGMformer, GluFormer, CGM-JEPA — encode a glucose trace as one entangled sequence. GlucoFM decomposes it into a slow physiological “state” stream and a transient “event” stream, keeps the observation mask intact, and pretrains with two JEPA-style latent objectives. The result is a 0.72M-parameter enco

Google Research and UNSW Sydney released GlucoFM, a foundation model designed to analyze continuous glucose monitoring data by splitting it into two separate streams: a slow physiological baseline and short-term fluctuations from meals, activity, or stress. The model uses only 0.72 million trainable parameters and outperformed larger existing models on 14 evaluation tasks, reaching 58.8 task-averaged PR-AUC compared to 54.7 for the strongest baseline. GlucoFM is currently a research prototype without regulatory approval and cannot be used clinically or as a consumer product, though the research team plans to release code and scripts so other teams with glucose monitoring data can reproduce it and run inference on standard computing hardware.

Google DeepMind’s WeatherNext 3 Trains on Weather Station Observations to Deliver 5 km Global Forecasts, Refreshed Every Hour
AI weather models have spent three years closing the gap with physics-based forecasting, but two problems stayed open: resolution too coarse for local terrain, and initialization tied to numerical weather prediction (NWP) analysis that arrives about six hours late. WeatherNext 3, released by Google DeepMind and Google Research, attacks both. It takes a live global geostationary satellite mosaic as a direct model input, re-initializes every hour, and emits forecasts down to 0.05° (~5 km) while t
OpenAI Releases GPT-6 Astra: A 1.05M-Context Computer-Use Model Gated Behind a ‘Critical’ Cyber Threshold
Today, OpenAI released GPT-6 Astra. The company calls it its most intelligent and aligned model, and positions it primarily as a computer-use system rather than a chat model. The pitch is that Astra operates software the way a person does, across browsers, spreadsheets, desktop applications and terminals, and finishes multi-step jobs instead of describing how to do them. Is it deployable? Partly, and not on your own hardware. Astra is a closed, hosted model with no released weights, so self
