Grok 4.7: 38% on Terminal-Bench in xAI's harness, 26% in an independent one, and on by default in Copilot

California's seven data centre laws cap nothing, and state energy reporting skips every site under 10 MW

California's new data centre laws make operators pay for grid and water upgrades. They do not cap use, and the EU's reporting threshold is one twentieth of California's. What UK cloud buyers should ask instead.
