Fenghe goes open-source as Global Initiative kicks off

China's meteorological authority has open-sourced Fenghe, a 100-billion-parameter LLM trained on 50 million tokens of weather data and Earth system observations, positioning it as the first open-source meteorological foundation model. The initiative aims to build a global collaborative ecosystem for AI-driven disaster prevention and climate resilience. A trained, production-ready climate model just entered the commons. If you're building weather risk, disaster prediction or climate adaptation tools, you now have a free featurised starting point that China validated at scale - and you need to move fast, because every climate-tech founder with a GPU just got the same opportunity.
