The day after OpenAI released GPT-5 and made it free for all users, xAI CEO Elon Musk announced: Grok 4 will be free for all users for a limited time.
His tone was even more assertive: he repeatedly hinted that Grok 4 still outperforms competitors, and even boldly claimed that Grok 5 will launch before the end of 2025—"so good it will crush the competition."
This wave of "limited-time free access" is both about user retention and direct confrontation.
