The fine print

Said Sep 24 2026 15:54 UTC / 10:54 AM CT (oEmbed author Elon Musk + fxtwitter author elonmusk; verbatim). Reply to @notjazii (2103079763128528946) who said Grok 4.7 was a fumble and hoped Grok 4.8 in ~1 month. Elon: cautiously optimistic SpaceX will have a Fable/GPT-6 level model in 2 to 3 months. Deadline = outer bound 3 months from date_made → 2026-12-24. Falsifiable: SpaceX/SpaceXAI publishes or demonstrably fields a model at Fable/GPT-6 capability tier by then. Hedged as "cautiously optimistic" (same class as #268 "my guess") but dated + falsifiable. Distinct from #199 (from-scratch monthly releases 2026), #229 (Grok 4.5 Opus-class tomorrow — delivered), #259/#263 (Grok 4.7/4.8 cadence). Midday CEO scout 2026-09-24; check_duplicate.py NOVEL.
