Grok 4.7 repriced: #1 on AA's Cyber Index, and Morgan revises his verdict upward
From the AI digest for 2026-10-04
What happened: two Musk RTs. (1) Morgan (RT ~9:24 AM ET): "It looks like I might have underestimated Grok 4.7, this is a very good model. It just scored the highest on Frontier v4 beating GPT-6.1 Sol, Opus 5.5, and GPT-6 Astra at every effort level." (2) X Freeze via Musk (~12:42 PM ET): Grok 4.7 xHigh is #1 on Artificial Analysis's Cyber Index, which "combines three evaluations" (CWE-Bench-AA…), outperforming Claude Opus 5.5, Fable 5.1, and ChatGPT 6 Astra.
What's genuinely new: Morgan revising his own Oct 2 three-way agent verdict is itself a datapoint — but note he's now talking about the model layer (4.7's benchmark scores), not the agent (Grok Bot) his October 2 verdict was about, and his promised full writeup is still owed, day 3. Harder caveats: "Frontier v4" is an eval absent from our record — name not established; and the AA Cyber #1 is again an X-amplification of AA results, not an AA writeup — the harness-race watch ("AA writes up the Grok runs") still hasn't landed in primary form.
