Grok ‘High Demand’ error leaves users with limited access to chatbot [Updated]

Update 23/04/26 – 05:52 pm (IST): Some users, like the OP on this Reddit thread, suggest that accessing Grok through the X platform (https://x.com/i/grok) is one way to get around the “High Demand” limitation.

Another suggested workaround is to use the “Speak” function and talk to Grok using voice instead. This, of course, isn’t an ideal workaround for every situation, but it might be worth a shot anyway.

Original article published on April 23, 2026, follows:

Grok has been practically unusable for the past 24 hours, throwing a “High Demand” error at almost everyone trying to generate text.

The disruption is widespread and affecting both free users and those paying for premium tiers. The exact error message tells people the system is under heavy usage and suggests they upgrade their plan to get priority access.

The irony is that the issue is impacting paid users too. So the push to get people to pay for the same degraded experience doesn’t make sense at the moment.

In fact, it has been a pretty bad day for X platforms overall. Earlier today, we covered an annoying bug on X causing video audio to double up and play completely out of sync. Now the AI side of the site is buckling.

Over on Reddit, users are losing their patience. Multiple threads have popped up highlighting the ongoing outage. Some are even reporting that the service is either entirely down or returning a “currently unavailable” message.

Some users say the voice chat feature using the Expert model still works fine for hours. But standard text prompts are a no-go for most accounts.

The exact cause of the server strain is not officially confirmed. A lot of users suspect xAI is intentionally throttling the free tier to force people into buying SuperGrok. It is a common theory whenever a freemium service suddenly locks up behind a paywall prompt.

But there might be a very real technical reason for the traffic spike. Just yesterday, we reported on a major Grok update that rolled out custom templates and smarter video extensions. Big feature drops almost always cause a massive surge in active users testing out the new tools.

In addition to that, SpaceX — which officially folded xAI into its massive corporate umbrella earlier this year — announced a landmark deal with the wildly popular AI coding startup Cursor.

The arrangement gives SpaceX the right to either buy Cursor outright for $60 billion later this year or pay $10 billion for joint development work. Ahead of the announcement, reports already leaked that Cursor was tapping into xAI’s Colossus supercomputer, pulling tens of thousands of GPUs to train its own next-generation coding models.

If xAI is suddenly routing that much raw compute power to fuel Cursor’s backend, it is not hard to see why standard Grok users are getting squeezed out. Add in the quiet rollout of the Grok 4.3 beta, and you could see why the servers might be under heavy load.

That said, take this with a grain of salt since it’s all speculation for the most part. We’ll just have to wait for an official word to know the exact reason. But I wouldn’t hold my breath on that.
