While one of the more common places to see Grok being used is on X, the LLM AI chatbot is available elsewhere. Naturally there’s the standalone app, as well as the basic web version. Whichever way you access it, xAI, the company behind Grok, says it’s giving everyone access to Grok 4. As the name suggests, it’s the latest and most powerful version of the chatbot.
On a whole, this is good news, but this does come with some caveats. To start, while you don’t have to pay to use the new model, you can’t use it without signing in. Remaining signed out leaves you locked to using Grok 3, or more specifically, the Fast mode.
The next snag may hit once you’ve signed in. While it’s not explicitly stated in the announcement post by xAI on X, this caveat comes from the Grok account instead. Replying to another user, the account notes that free users will get a limited number of prompts, though it didn’t specify what those limits were. Instead, it only gave an example of five prompts per 12 hours.
All that being said, we gave it a try for ourselves, and managed to get over 10 prompts without getting locked out. With that in mind, your mileage may vary as to what is your prompt limit. Though it’s probably worth mentioning that the move comes shortly after OpenAI did the same for GPT-5, results notwithstanding.
