The authors say it handles precipitation, wind and pressure, including extremes, at roughly one-three-hundredth the cost of the high-resolution physical model. It only works with ACE tuned to X-SHiELD and cannot directly simulate warmer futures or ERA5 historical climate.</p><p>Recommendation: TRIAL</p><p>Sources: <a href="https://huggingface.co/blog/allenai/hiro-acev2">HiRO-ACEv2 release</a> · <a href="https://huggingface.co/allenai/HiRO-ACEv2">HiRO-ACEv2 model card</a></p>
