🌦️ Which weather model is most accurate? We score them every day, in the open.
We released two things on Hugging Face:
🏆 Global Weather Model Leaderboard Every day it records what each global model predicted for 24 world cities, compares it with what actually happened (ERA5), and updates the ranking. ECMWF IFS and AIFS, NOAA GFS and AIGFS, DWD ICON, JMA, ECCC GEM, MET Norway, side by side, on the same cases, since 1 January 2026.
Four elements, four tabs: max temperature, min temperature, wind, precipitation. Forecast leads from 1 to 7 days, with 8 to 10 days joining as they are verified.
🧬 Darwin-Prediction-Weather VIDRAFT's weather prediction system: a fusion engine that combines global forecasts, learning only from days already observed. It holds the lowest error in all four elements at every lead on the 2026 record, and the lowest error in all 15 evaluated cells of the WeatherBench 2 (2020) protocol.
What the 2026 record shows so far: • AI models now lead physics models at the major centres (AIFS vs IFS, AIGFS vs GFS) • Fusion goes further: 7-day max temperature RMSE 2.09 °C vs 2.41 °C for the next model
Also inside: yesterday's results with a daily WIN for the closest model, a 10-day outlook for every city, champions by city and by month, and a Live Earth map with wind, clouds, radar and temperature.
Every forecast and every observed value is open as CSV, so anyone can check the scores.
🛑 What if the kill switch lived inside the model itself? For 50 years, the operating system lived inside the computer. Now the operating system lives inside the AI. Today we're sharing ViKernel : Weight-Native OS, a Secure OS wired directly into the weights of an LLM. 🔧 How it works ViKernel wires CPU, NPU (vector unit), RAM and ROM circuits into the model weights, runs them accelerated on GPU or NPU, and boots a Secure OS on top. ⚡ Boots in the weights: change a single byte and it locks itself ⚖️ Decides in the weights: every action is allowed or blocked by rule, and persuasion does not change the verdict 🔗 Remembers in the weights: every decision is sealed in a tamper-evident chain 🛑 Stops in the weights: anyone can stop it, and restarting requires a signed key The original weights stay untouched, so the model keeps its skills. It plugs into any LLM or VLM. Why the kill switch belongs inside the model: external guardrails can be removed, argued with, or rewritten. A switch that travels with the weights cannot be left behind. We see it as one layer of defense in depth, alongside hardware stops where you have them. 📖 Read the full write-up: https://huggingface.co/blog/FINAL-Bench/vikernel-why-the-kill-switch-must-live-inside-the 🖥️ Try the desktop demo (Terminal, Kill Switch Lab, Leak Test, Audit Viewer, and a Kernel Guard game): FINAL-Bench/ViKernel-Desktop Try it in 30 seconds: press 🛑 KILL, type run weather (refused), then resume --key vikernel-demo.
