Our take
Hi Dotikers!
Five years ago, accurate 15-day weather forecasting required government-scale supercomputers. Nvidia just changed the game with two open source models that run on a single graphics card.
The Earth-2 Medium Range and Earth-2 Nowcasting models mark a clever technical shift: they ditch the specialized architectures of their predecessors in favor of transformers, the same building blocks powering ChatGPT and Claude. The logic is sound. Rather than reinventing the wheel, Nvidia taps into the optimization ecosystem already battle-tested by the LLM industry. The result? A 15-day forecast that, according to Nvidia, outperforms DeepMind's GenCast across more than 70 weather variables.
On resolution, the Nowcasting model reaches one kilometer where NOAA's GFS model tops out at 13 kilometers. For a farm operation or a power grid manager, the difference between "rain in your county" and "rain on your field" changes everything.
But the real masterstroke might be the Global Data Assimilation model. This data preparation step, which used to consume up to 50% of traditional weather centers' computing resources, now runs in seconds on a single GPU. Your smartphone probably has more power than needed.
This democratization comes at the right time. Between extreme weather events and the energy transition, meteorology is no longer just small talk material. It's becoming critical infrastructure that private players can now master without needing a government-sized budget.
