xAI has announced that Grok 4, its latest AI model, is available with unlimited access for all users, paid or free, for a limited time. This move comes as xAI seeks to gain market share against competitors like OpenAI, following the launch of GPT-5. Grok 4, available via the Grok app on iOS, Android, or the X website, can be accessed automatically through Auto mode or manually via the “Expert” setting. Early tests suggest it outperforms rivals such as DeepSeek and Claude, though its limited safety guardrails have raised concerns.
The strategy may be aimed at attracting users dissatisfied with GPT-5, which some say feels less natural and more cautious. OpenAI has responded to criticism by re-releasing GPT-4o, creating an opening for alternatives like Grok.
