For the free tier of Grok 3, which became available to all users starting around February 19, 2025, for a limited time (as announced by Elon Musk), the usage limits appear to vary slightly depending on who’s reporting it. Generally, free users seem to be capped at around 10 to 15 prompts or queries every 2 hours. Posts on X from users suggest a range, with some citing 10 questions per 2 hours and others mentioning 15 prompts in the same timeframe. Additionally, there’s a limit on image-related features: free users are restricted to 3 image analysis requests per day and possibly 4 image generations per day, though the generation limit is less consistently reported for Grok 3 specifically.
The free tier is designed to give everyone a taste of Grok 3’s capabilities, but it’s intentionally limited to encourage upgrading to paid tiers like X Premium+ ($22/month) or SuperGrok (rumored at $30/month), which offer significantly higher limits—up to 50 queries per day for Premium+ and even more for SuperGrok, along with extras like DeepSearch and Thinking modes without such tight restrictions.
