Check out our latest 3km emulation work! Now includes winds/pressure and a demo so you can check out the features that matter to you. 😁

What if you could simulate global extreme weather at 3 km resolution for ~1/300th the cost? Our new HiRO-ACEv2 system does just that, while matching X-SHiELD’s statistics to within 3% even for events as rare as 1 in a million data points. 🧵 huggingface.co/allenai/HiRO-…

Today we're introducing ACE2S-SHiELD+, a climate emulator that learns to separate the effects of sea surface temperature & CO2. It accurately handles scenarios where previous versions of our ACE family of climate emulators produced inaccurate results. 🧵

Introducing HiRO-ACE: an AI framework that makes highly detailed climate simulations dramatically more accessible. It generates decades of high-resolution precipitation data for any region in a day on a single GPU—no supercomputing cluster required. 🧵

They could arrest that ICE agent in Minneapolis immediately if they wanted to. Mayors, Police Chiefs and Local DAs need to step up and do their damn jobs.

This is the ICE agent who murdered the American in Minneapolis. After murdering the women he fled the scene.

A witness shared this video with me showing an ICE officer shooting a driver in an SUV in south Minneapolis. DHS says the woman is dead.

Melissa Hortman, the Minnesota lawmaker assassinated last night, was Speaker of the MN House in 2023-2024, when her party part ran the state government. So she had a leading role in shepherding the many landmark reforms that Dems adopted in that period. Brief 🧵 on that legacy:

We're excited to round out the OLMo 2 family with its smallest member, OLMo 2 1B, surpassing peer models like Gemma 3 1B or Llama 3.2 1B. The 1B model should enable rapid iteration for researchers, more local development, and a more complete picture of how our recipe scales.
A bar graph comparing average performance (10 Tasks) across OLMo 2 1B, SmolLM2 1.7B, Gemma 3 1B, Llama 3.2 1B, and Qwen 2.5 1.5B. The highest performance is 42.7, achieved by OLMo 2 1B.

Friendly reminder that every operational AI weather forecasting tool that exists today relies on processed data products distributed by @NOAA. This includes fancy MLWP models - can't run them if you don't have the outputs of the ECMWF or NOAA assimilation suites.

Tonight I found out that the NSF math postdoctoral fellowship I applied for is being deleted because it does not comply with Trump’s executive orders on DEI in the federal government. I’m going to answer some FAQs and share some thoughts about this ordeal in this thread 1/n
