Grok 5 is still deep in training on the massive Colossus II cluster. Roughly 220k high-end NVIDIA GPUs are already online, with more being added. Power draw is sitting around 1 GW and climbing. The model is targeting the 6 to 10 trillion parameter range, which puts it in a completely different league from anything currently public. Training has been running since at least January. Elon recently confirmed it should arrive before the end of 2026 and will be trained on the full 25-year SpaceX engineering data set. That combination of extreme scale plus proprietary real-world engineering data is the real story here. This is not another incremental Grok 4.x update. It is the much larger architectural and compute jump happening in the background while the smaller releases keep rolling out. When it lands it should give SpaceX a serious internal edge on engineering, simulation and design problems that current models still struggle with. Cursor is already running on the same cluster, so the jump in capability should show up there too. No firm date yet, but the ambition on both compute and data is very real.
