3. NEXT-RELEASE FORECAST & PLAIN-LANGUAGE METHOD
How We Estimate the Next xAI Release Window
Plain-language method: We take the last 4 public release gaps for xAI:
The shortest of those 4 gaps is 35 days, the median is 46 days, and the longest is 69 days. Adding those intervals to Grok 4.7 (2026-09-21) places the historical cadence window between 2026-10-26 and 2026-11-29 (median date: 2026-11-06). Rough estimate from 4 gaps ranging 35 to 69 days. Labs do not follow schedules.
