Website interface with Grok 3 model is being offered for free experience.

To use Grok 3, users need to visit grok.com, then click on the Grok 2 or Grok 3 option. However, Grok 2 does not require a login, while users need to register, or connect with an X account or Google account to access xAI's latest AI. Once done, users will type a query request into the chat box for the AI ​​to respond.

In addition, users can experience the mini version of Grok 3 right on the social network X. When clicking on the xAI logo on the right side, a chat box appears for quick queries, such as summarizing the content of an X post or asking the problem you need. According to the introduction of Grok 3 mini itself, this is a version that "has all the intelligence and humor of Grok 3" but is optimized to run more efficiently, supporting reasoning queries, deep search (DeepSearch) and answering questions about world knowledge, mathematics, programming.

Practical experience shows that the new AI has a fast response speed, natural language as well as Vietnamese support. The image generation speed is slower than competitors such as Meta AI, but the images are somewhat more true to the creator's description.

It's unclear how long xAI will let users experience Grok 3 for free. On X, Elon Musk's company said that X Premium+ and SuperGrok users will get increased access to Grok 3, in addition to early access to some advanced features like Voice Mode.

Grok 3 was launched on February 18, and Musk called it the "smartest chatbot on Earth". In the livestream announcement, xAI presented a series of benchmark tests to show that Grok 3 is higher than Gemini 2 Pro, Claude 3.5 Sonnet, GPT 4o, and DeepSeek V3 when considering Math, Science, and Cryptography benchmarks. In addition, the AI ​​is also equipped with reasoning capabilities that allow for deeper thinking when processing queries.

After Grok 3 was unveiled, some early adopters said they were impressed with the new AI. "Oh my god! It was one of the most surprising and rewarding hours of my life," Musk's girlfriend Shivon Zilis wrote on X. She added that Grok 3 is friendly and polite, and knows how to make people understand by only answering half of the question, leaving the other half to think and respond, or giving open-ended instructions to absorb the content of the story.

"I had an early experience with Grok 3. I was really amazed, the model is very impressive. Congratulations to Elon and the team for bringing it to life," commented famous computer scientist Lex Friedman.

'Grok 3 is somewhere near OpenAI's strongest model and is better than DeepSeek-R1 and Gemini 2.0 Flash Thinking,' Andrej Karpathy, a co-founder of OpenAI who has since left the company, wrote on X. 'The model is clearly very fast and powerful.'
