Theo: Grok 4.7 costs 2x more than 4.6

Elon Musk promised Grok 4.7 would beat 4.6 in every way with even better token efficiency. Theo says he cannot find a single benchmark where that is true, and real-world costs came out over 2x higher.

Theo ran Grok 4.7 on real engineering tasks and called the release disappointing: token efficiency down 30 to 80%, worse scores than 4.6 on various benchmarks, and real-world costs over 2x higher.
