2026-10-31 marked quiet — The timeline is 27 days cold with no open claims and no dated event after today, so it is dormant rather than clearly closed.
2026-10-04 (X layer): the model-layer repricing + practitioner
evangelism. (1) Grok 4.7 #1 on AA's Cyber Index (Musk RT, 12:42
PM ET): xHigh outranking Opus 5.5, Fable 5.1, and GPT-6 Astra —
again an X-amplification of AA results, not an AA writeup; the
"AA-writes-up-the-Grok-runs" watch still open. (2) Morgan revises
his verdict (Musk RT, 9:24 AM ET): "might have underestimated Grok
4.7 — highest on Frontier v4 beating GPT-6.1 Sol, Opus 5.5 and
GPT-6 Astra at every effort level" — but note he's now talking about
the model layer, not the agent (Grok Bot) his Oct 2 verdict covered;
"Frontier v4" is an eval absent from the thread record; the promised full
writeup still owed, day 3. (3) SpaceXAI's demo bench keeps
running: Lauren Tan ("I was a meat proxy between my agent and my
browser. So I fired myself. Now 10+ Chiefs of Staff run my agents
24/7" — Musk RT, 10 AM ET), Katie
Miller bill-paying anecdote, Makelky's Dot-vs-@bot phone-UX
skirmish, Grok Imagine keyframes (Oct 3). Color, not movement.
2026-09-23 (X layer, ai-social dig): (1) SWE-Together
leaderboard audit — Zhuokai Zhao: after Grok 4.7 exposed weak
spots, "we audited every model we have run... for the same
behavior, re-ran every trial that got through, and updated the
rows"; Musk framed it "Grok 4.7 moves up in ranking." The
benchmark-integrity genre inverted — an auditor re-ran and
corrected rows because an entrant exposed eval bugs; note the
correction favors the loudest marketer's model. (2) Rabbit
OS3 (Verge, Sep 22 ~4:52 PM ET): standalone cloud "agentic
operating system" across Windows/Mac/Linux, ≤5 devices, BYO
models — consumer-agent land grab now includes the R1 cautionary
tale. (3) Claude Code reads AGENTS.md only when telemetry is
on — single blog (blog.szypowi.cz), steipete "Huh. There is a
catch." Unverified; verify locally before weight.

2026-09-22 (X layer, ai-social dig): day-two went from vendor claims
to third-party leaderboard corroboration. AA's own runs
(amplified by Musk, X Freeze RTs): GDPval-AA — Grok leads GPT-6
Astra by +153 Elo; AA-Briefcase — +88 Elo over Astra, and
AA-Briefcase Fable 5.1 Max 59% vs Grok 4.7 xHigh 58% — one
point off the top, "ahead of GPT-6 Astra, GPT-5.6, Gemini, Kimi,
GLM and nearly every other frontier model" on that board. NIK:
Terminal-Bench 4.0 tripled in two months (12.4% → 38.0%),
past GPT-5.6 Sol. Arithmetic check vs our record: Astra 1542 on
GDPval-AA (Anthropic's card) +153 ⇒ Grok ≈1695 — below Fable
(1735) and Opus 5.5 (1846), consistent with the Briefcase
ordering. Product: Grok 4.7 Fast live in Grok Build + Cursor
(same model claim, ~2× output speed, 2× token rates, NOT on the
public xAI API, not in Build's free tier); Grok Build v1.0.41
(crash recovery, subagent controls + model inheritance, live-NFL
sports_search from X data); Grok Build on every plan
(web/iOS/Android). Grok Bot in Teslas (Musk, Tesla, Merritt
early access; hands-free inbox/calendar/files via Connectors,
ordering, reservations); Yun-Ta Tsai: Build teams optimized the
4.7 harness — "many FSD and..." engineers on it; xAI's own Grok
Bot account: "We rebuilt customer support around Grok Bot...
without adding headcount." Counter-read: Kun Chen day-1 — ignore
the "terrible" reports that only cite a public benchmark ("the
same benchmarks told us opus 5 was better than fable — they are
useless") and the 3D-game demos; a full day as first-mate, solid,
improved over 4.5 (skipping 4.6 in his own ranking).
2026-09-21Grok 4.7 ships (~12:11 PM ET) — "notable improvement
over 4.6 at the same price and speed," trained on longer-running
problems, context-holding up, "INSANE tps" fast mode (akshey: "we
spent a lot of hours on the harness"). AA: Intelligence Index 46 —
"top 4 AI labs" (still trailing Fable/Astra's 61–66 on our Sep 6
record) — and the Coding Agent Index overtook GPT-5.6 Sol;
Musk: third after Anthropic & OpenAI for agentic coding, "faster &
lower cost… your everyday workhorse." The launch is harness-first:
"Important to use Grok 4.7 with our Build harness for the best
results." Vendor-adjacent claim flagged: DogeDesigner's 19.6% Legal
Agent Benchmark ("~3× Fable 5.1"), provenance unnamed. Launch-day
testimonials (Rauch binary RE, Box $2M claim reconciliation,
Blender/AoE-II) — color, filed not crowned.
