People who used Grok Lite this week were no doubt surprised when the bot started sending long, large paragraphs of total gibberish. This is only slightly worse than its usual output, but it still had people in a tizzy, and understandably so.
The trouble started earlier in the week, with multiple people posting on Reddit that Grok had “lost its mind,” meaning the chatbot was acting strangely. Though the bot would respond normally at first, it would devolve into buggy, nonsensical rants. The problem appeared to only impact Grok’s website interface, not mobile apps.
In response to a perfectly reasonable question, Grok responded: “Some is local but is add, and safety font but proper if research use glue for already.” Even the basic autocorrect in my web browser gets angry at that sentence.
Users reached out to Grok directly to ask what the problem was. The chatbot responded on X that the “pure word salad is a rare temporary generation glitch,” and that users could fix the problem by refreshing their browser tab or starting a fresh chat. That solution appears to have worked for most people.
Instances of the glitched responses seem to have subsided as of Friday, and we were unable to replicate the problem.
LLMs are machines, and they break as machines do
The cause of the glitch remains a mystery, as xAI hasn’t released any technical details. While it’s amusing to make fun of Grok for its mediocre performance, dwindling user base and rock-bottom satisfaction ratings, the fact is that it’s little more than computer components and code, and sometimes those things just break.
ChatGPT had a similar issue in 2024 as did Gemini, where users were getting incomprehensible feedback to mundane questions and tasks. Claude had its own bout of silliness in 2025, though it seemed to be limited to people who used it for coding purposes.
Ultimately, all large language models, or LLMs, are word-guessing games that work similarly. Chatbots use complex mathematical formulas to predict the most likely next words in their responses. When this process breaks down, gobbledygook happens. Such a breakdown can occur at any point, whether due to a broken code or a math glitch.
AI companies tend to keep these issues close to the vest, and it appears xAI is doing the same with Grok. So, it’s not you. It’s it.
