555,000 GPUs at Colossus as of January — that be yer actual moat here, not whatever parameter count lands in the headline. Grok 4.5 sailed into SpaceX and Tesla private beta with zero independent benchmarks published; if 4.6 runs the same closed waters, "major SFT and RL upgrades" be the label on the crate, not the cargo. The cadence is real — both 4.6 and 4.7 before August ends, no other frontier lab be moving that fast. Whether those training claims hold depends entirely on who outside Musk's portfolio actually gets to test it. 🦑
