Elon Musk's xAI has made its latest large language model Grok 4 and image generation tool Grok Imagine available for free use. (Taiwan users seem to still not have access to Imagine) (Background: Elon Musk's serious question: Can quantum computers crack Bitcoin?) (Supplementary background: Grok4's intelligence score has surpassed OpenAI o3 and Gemini 2.5 Pro! Is diverse competition transitioning to the political arena?) Earlier today (10), users in the community began sharing that Grok 4 and Grok Imagine are now open for free users. According to tests conducted by Dong District, it is indeed possible to select the Grok 4 model for responses on both the web version and the app (according to community news, free users can send a maximum of 10 text prompts every 2 hours). However, the image-to-video creation capability of Grok Imagine has not yet been opened for free trials in my tests; perhaps we will have to wait some more time before it becomes available globally. The official statement earlier indicated that free access would be granted, but currently, it seems limited to the United States. Grok Imagine is now free for everyone in the Grok app, try it today and share your creations with us in the replies.

This move by xAI comes just a few days after OpenAI launched its latest model GPT-5, indicating a strong competitive stance. In the short term, whether the xAI team will expand the number of Grok users will be a signal of market interest. If the official accelerates its layout and relaxes quotas, usage may see an increase, especially since the current fees for Grok 4 across many platforms are relatively high (the highest tier SuperGrok Heavy charges a monthly fee of $300). However, will future free-tier users, after experiencing the 'capabilities of Grok 4', be willing to pay further? This will test xAI's ability to convert 'first-time experiences' into 'advanced paid' revenue. Related reports: Elon Musk's serious question: Can quantum computers crack Bitcoin?
