The launch of ChatGPT 5 was expected to bring a surge of excitement for OpenAI, but early signs suggest that some users are moving in a different direction. On X (formerly Twitter), several verified users and companies have been voicing that they are now relying on Grok, the conversational AI developed by xAI, instead of sticking with the latest version of ChatGPT.
One company account, InsPaction, shared that it had already replaced ChatGPT with Grok for daily work tasks. The post read, “Lately our company changed ChatGPT with @grok for our work and daily tasks. Way more better. Try it.” While brief, the message highlights a growing trend of organizations experimenting with alternatives to ChatGPT, especially after the arrival of its newest version.
Another sign of Grok’s rapid rise came from user X Freeze, who highlighted Grok’s impressive download figures. According to his post, Grok recorded 4 million downloads on iOS in July alone. A chart sourced from Similarweb also showed Grok leading all other generative AI apps in month-over-month growth, with nearly 30 percent, far ahead of Perplexity at 13 percent and ChatGPT at just over 6 percent. Meanwhile, competitors Gemini and DeepSeek saw negative growth during the same period. The post quickly gained traction, amassing over 2.6 million views, reflecting the growing excitement around Grok’s expansion.
Felix Urbanek, another verified user, also stated he has shifted much of his AI usage to Grok. “I have started using grok much more than ChatGPT lately. Great ai,” he posted. His short review adds to the steady stream of endorsements Grok has been gaining on social platforms.
The timing of these comments is significant. OpenAI recently released ChatGPT 5, an update that promised improvements in reasoning, memory, and real-time interactions. However, early chatter suggests that not all users feel the upgrade has been compelling enough to keep them from exploring alternatives. Grok, backed by Elon Musk’s xAI, has positioned itself as a faster, more conversational, and more context-aware assistant, something that may resonate with users looking for fresh experiences.
Social media buzz often reflects early adoption patterns, and the current wave of posts shows Grok gaining traction among both individuals and businesses. The shift does not necessarily mean ChatGPT is losing its entire user base, but it does highlight how competitive the AI space has become in 2025. With more companies offering AI chat solutions, user loyalty can quickly shift depending on performance, accessibility, and the overall brand perception.
For now, it appears that Grok’s appeal lies in its simplicity and perceived responsiveness. Posts praising it are growing, while some ChatGPT users appear hesitant to move on from what they already know. The conversation is less about abandoning ChatGPT entirely and more about having alternatives that people are willing to test.
As the rivalry between OpenAI and xAI heats up, user reactions on platforms like X may shape how these companies position their products going forward. If Grok continues to gain positive feedback and sustain its rapid growth, OpenAI could be pressed to push more innovative features beyond what it introduced in ChatGPT 5.
What is clear is that users are not shy about sharing their opinions publicly. And for now, Grok seems to be riding a wave of goodwill, while ChatGPT 5 is still working to convince its audience that it is worth staying with.
