Previously, Musk had already hinted that Grok 3 would be a very powerful AI model. Earlier, it was finally officially released, and the development team shared a lot of test data. I have to say it’s really quite strong—it beat OpenAI’s GPT-4o in multiple tests, and even o1 and o3mini (high) as well. There are also ways to try Grok 3 for free right now, and I’ve compiled them all below for everyone.
Grok 3 has officially launched, featuring exceptionally powerful reasoning capabilities.
According to the introduction, Grok 3 was trained using 200,000 GPUs, with computing power more than 10 times that of Grok 2, meaning it has stronger reasoning and autonomous agent capabilities. In benchmark tests across mathematics, science, and programming, it has beaten nearly all competitors.
In performance benchmark tests, math (AIME’24) Grok-3 scored 52 points, and Grok-3 mini also scored 40, both beating other competitors. The same applies to science tests (GPQA) and programming (LCB Oct0Feb), where Grok-3 and Grok-3 mini both lead:
Next is reasoning and test-time compute. The Grok-3 series performed best across all tests, with Grok 3 mini Reasoning leading Grok-3 Reasoning Beta in mathematics and programming:
In the AIME 2025 performance test, Grok-3’s reasoning ability is also the best, especially the test version, which even leads against o3-mini (high):
This version also includes the DeepSearch feature, allowing users to enable Grok 3’s DeepSearch for more comprehensive analysis and complete report generation. As with other AI services, users can expand to view Grok’s reasoning process and access key cited sources.
In addition, to enhance the reasoning experience, Grok 3 also offers two interaction modes: “Think” and “Big Brain.”
- “Think”: Relies on the smaller Grok 3 mini model, suitable for simple queries.
- Big Brain: Uses the full Grok 3 to handle more complex problems.
In the video demonstration, the xAI engineers showcased building a game that blends elements of Tetris and Bejeweled:
However, Grok 3 is only available to X Premium+ subscribers, and the official version cannot be used for free. But it has been announced that Grok 3-mini will be free for all users in the coming days:
Excited to be a member of the amazing team at @xai , and shipping the best grok3!
Thrilled to lead grok3-mini training, and will ship it to all users for free in the coming days! LFG! pic.twitter.com/EAQqmSCpn3

How to try Grok 3 for free?
Although the official version doesn’t offer it for free, there’s still a way to try Grok 3 right now, which is throughChatbot ArenaIt’s just the Early-Grok-3 early model, so there’s bound to be a difference compared to the official Grok 3, but the performance is still quite good.
After clicking the link above to go to Chatbot Arena, please open Direct Chat; the default is the early-grok-3 model:
