Musk Commits to a Two-Week Grok 4.6 and a Four-Week Grok 4.7, With 2T Parameters Aimed Squarely at Kimi K3
Elon Musk posted on X on July 24, 2026 that xAI will ship Grok 4.6 in two weeks and Grok 4.7 four weeks out — a materially tighter schedule than the late-August-to-mid-September window analysts had inferred from his July 18 statement that pre-training would finish the week of July 20–27. Grok 4.6 is a 2-trillion-parameter model Musk describes as better than the current 1.5T Grok 4.5 'in every way' while holding throughput near 80 tok/s, and he has explicitly positioned it against Moonshot's ~2.8T Kimi K3. Nothing official exists for 4.7 beyond the date; speculation in the 191-comment r/singularity thread puts it at 4–6T. Treat the cadence as a stated intention from a single source with a history of slipping timelines, not a shipping schedule.
