xAI severely throttling video, image, and voice features for paid Grok users [Updated]

Update 16/05/26 – 09:28 am (IST): Some eagle-eyed users have spotted a tweak in SuperGrok Heavy’s benefits that show up on the subscription page. Instead of the previous wording that said “Near-unlimited usage” (screenshot in the original post below), it now says “Highest usage limits.” 

While it might seem like a minor change, it indicates that xAI is indeed lowering the usage limits, even for SuperGrok Heavy subscribers. If you look at the bigger picture, it checks out. The partnership with Cursor, Anthropic, and the launch of Grok Build mean that xAI can no longer sustain the “generous” usage limits they offered just weeks ago.

Still, for users who paid for SuperGrok Heavy for a year upfront, this is a major change in the terms. You can join the ongoing discussion here.

Update 15/05/26 – 12:15 pm (IST): New evidence from user-shared emails suggests xAI may have quietly revised its own expectations around limits. An April support response claimed Heavy users could generate “over 100” videos per reset window, but a newer May email now puts that figure at “>80 per 12 hours,” while standard SuperGrok is listed at just “>20 videos” per 24 hours. The same message also confirms that moderated or failed generations still count toward the cap, and that 720p output can drop to 480p once limits are hit.

This lines up with the complaints we highlighted originally, where subscribers say they’re hitting caps far earlier than expected.

Original article published on May 13, 2026, follows:

Many paid Grok subscribers are facing severe and sudden rate limits across video, image, and voice generation. Users paying $30 a month for the SuperGrok tier report getting locked out of voice chats after just 20 to 30 minutes of use.

The throttling appears to be a sweeping, unannounced change hitting the platform’s core features. Video generation limits have plunged, with some users stating they are capped at just 20 videos a day.

This isn’t exactly a new problem, since we did highlight a similar problem earlier this month. But reports about the rate limits have been boiling over in the past 24 hours or so. And this time around, it’s not just about video generations.

Image editing allowances also took a major hit. One user noted their daily edit limit dropped from roughly 100 down to about 30 overnight.

Frustrated users are posting and discussing these seemingly unfair rate limits over on the r/grok subreddit. After reading over a dozen threads, a clear pattern emerges. Subscribers feel they are being squeezed off their base plans and pushed onto the $300 monthly Heavy tier.

In one active thread, the OP noted their voice session cut off after 20 minutes. The system then prompted them with an expensive upsell message to regain access.

Another highly upvoted post shows xAI pushing a $99 discounted upgrade to the Heavy tier right as the SuperGrok limits trigger. Many users see this as an aggressive tactic.

Even those already paying the top rates are feeling the pinch. One Heavy-tier subscriber mentioned their daily video limit dropped from 500 down to 160.

Adding to the frustration, even generations that are moderated still count against these shrinking allowances. So if the system flags a basic prompt, you lose that turn permanently. Speaking of which, we’ve already highlighted how Grok Imagine is now heavily moderated.

You can find more reports of these brutal 30-minute voice caps and sudden generation limits here, here, and here.

People who rely on the AI companion features for long drives or night shifts say the new limits render the service practically useless.

As one user said in a recent post, they watched xAI target the free tiers first, and now the paid users are getting hit.

It’s not hard to understand why folks are frustrated. After xAI managed to rope in millions with their loose moderation and generation limits, they pulled the rug and took away the very same features that got users onto the platform to begin with.

Many commenters are openly stating they have already canceled their plans. An xAI employee, however, responded to a few complaints about the voice limitations, noting that the limits for Grok can fluctuate daily. 

They also kept advising users to try again. Sadly, there’s still no official documentation covering the rate limits and what to expect.
