Elon Musk’s xAI has made its Grok 4 AI model accessible for free to all users worldwide, expanding availability just a month after its launch. Initially limited to SuperGrok and X Premium subscribers, Grok 4 now features generous usage limits for a limited time, enabling users to maximize its potential. The model offers two modes: Auto, which optimizes responses based on user prompts, and Expert, allowing manual switching to reasoning mode for detailed answers. In addition, xAI has introduced Grok Imagine, a free AI video generation feature that has sparked controversy for its ability to create explicit content, prompting scrutiny. Despite the free offerings, xAI maintains premium features for subscribers, indicating a strategy to balance user growth with revenue. Furthermore, Musk plans to integrate ads into the Grok interface to offset GPU costs. This move follows OpenAI’s launch of the freely accessible GPT-5 model, highlighting increasing competition in AI technology.
