Aurora is fully open! 🥳 The air pollution model 🌬️, the ocean wave model 🌊, and the TC tracker 🌀 are now available. And that's not all: all model weights (pretrained and fine-tuned) are now released under the MIT license. 😎 GitHub: github.com/microsoft/auro… #AIforGood

Flow Matching (FM) is one of the hottest ideas in generative AI - and it’s everywhere at #ICML2025. But what is it? And why is it so elegant? 🤔 This thread is an animated, intuitive intro into (Variational) Flow Matching - no dense math required. Let's dive in! 🧵👇

"Lost in Latent Space" presents an empirical study of latent diffusion models for physics emulation. They found surprisingly robust accuracy up to 1000x compression, enabling faster and more accurate simulations.

For a neural network, a grayscale image on a 50-by-50 grid of pixels is akin to a single point in 2,500-dimensional space. Given enough data points, the neural network may be trained to identify a specific type of image. quantamagazine.org/how-can-ai-id-…

Today in @Nature, we’re presenting GenCast: our new AI weather model which gives us the probabilities of different weather conditions up to 15 days ahead with state-of-the-art accuracy. ☁️⚡ Here’s how the technology works. 🧵goo.gle/49trAOv
I have been reimplementing some of the materials from the computational fluid dynamics course by @LorenaABarba in @marimo_io. Check out this interactive 2D diffusion simulation running entirely in the browser powered by WASM. marimo.io/p/@radi-radev/…
Playing around with jax-cfd to create some beautiful animations of turbulent flow. Next step learn a surrogate ML model 😋 github.com/google/jax-cfd

Our tutorial on diffusion & flows is out! We made every effort to simplify the math, while still being correct. Hope you enjoy! (Link below -- it's long but is split into 5 mostly-self-contained chapters). lots of fun working with @ArwenBradley @oh_that_hat @advani_madhu on this
