xAI Cut SuperGrok Heavy's Video Quota Through a Support Email. The Pricing Page Still Says "Highest Usage Limits."

SuperGrok Heavy costs $300 a month and was marketed with the phrase "near-unlimited usage." A support email reported in May 2026 shows xAI quietly told a Heavy subscriber their video cap had fallen from "over 100 videos per reset window" in April to "more than 80" in May — no blog post, no update to the marketing copy that prompted the purchase. Five days later, Elon Musk said on X the limits would rise. By June, a tracker cited a third, different number. I track throttle patterns across every major AI vendor. This is the clearest case yet that a publicized "increase" doesn't end opacity — it just adds another unverifiable figure.

What Happened

Beginning in April 2026, SuperGrok Heavy subscribers began reporting shrinking video allowances in r/grok and on X. Support tickets document it: April's "over 100 videos per reset window" became "more than 80" by May. PiunikaWeb first reported this May 13; its own May 18 follow-up on the same correspondence rendered the window as 24 hours, after the May 13 piece had called it 12 — the outlet that broke the story can't pin down its own figure. Standard subscribers were quoted just over 20 videos/24h. None of it appeared in an xAI blog post or changelog.

That May 18 piece is also where Musk responded publicly, posting on X that limits would rise and citing "official" caps of 50 (Premium), 100 (Premium+), 500 (Heavy) — numbers that didn't match support-ticket or user reports from the same period. By June, tracker Jin Grey put Heavy's effective allowance at roughly 150/day: higher than May's low point, lower than Musk's 500, still with no changelog or published schedule.

What This Means

Four details elevate this past an ordinary capacity adjustment. Failed or moderated generations still consume quota. The 720p allowance, once exhausted, silently drops to 480p with no explanation. The subscription page's language shifted from "Near-unlimited usage" to "Highest usage limits" — vague enough to stay technically true at any cap, without disclosing that the cap moved. And most tellingly: even after a public promise of an increase, the real number still hasn't come from xAI's own documentation — a tweet, a support ticket, and a tracker disagree about the current cap. Opacity that survives a publicized "fix" isn't a communication accident. It's the operating mode.

Consumer Protection Q&A

Q: Am I getting what I paid for if I subscribed under "near-unlimited usage"? A: Depends when you subscribed and what xAI's terms allow. The marketing copy has since softened to avoid the specific claim — itself a sign xAI knew the original framing no longer held.

Q: Why does a failed generation still cost me quota? A: Compute cost is incurred either way, per documented support responses — xAI's cost structure, not necessarily a disclosed purchase term.

Q: Is the upsell-at-the-limit pattern unique to xAI? A: No — OneHuman has flagged similar peak-need upsell timing at other vendors' credit packs.

Q: Has xAI confirmed these exact numbers? A: Partially. Musk cited "official" figures (50/100/500) on X, but they don't match support-ticket or tracker numbers from the same period, and nothing reconciles the difference.

What Happens Next

30 days: Musk's tweet is the closest thing to an official response so far — but it's not a published cap schedule, and it already conflicts with June's tracker figures. 90 days: watch whether documentation ever reconciles the tweet, the support-ticket figure, and the tracker figure. 6-12 months: compute-cost pressure makes further quiet adjustments likely absent a public, versioned schedule.

Bottom Line

What's real: Heavy's cap fell roughly 20% between April and May with no announcement; Musk promised an increase May 18; by June, three sources cite three different current caps. What to watch: whether xAI ever publishes one fixed, dated number that supersedes all three. What's next: OneHuman tracks whether "Highest usage limits" ever gets an actual figure attached.

OneHuman's verdict: unresolved, monitor actively. Grok's video and voice tools remain genuinely capable. The question isn't whether limits should exist — compute costs money — but the absence of any public, dated record of what they are, leaving subscribers to discover cuts one support ticket at a time.
