Grok 3: xAI’s Latest AI Chatbot Takes on ChatGPT and Deepseek

Musk’s AI company, xAI, has released Grok 3, its most advanced chatbot. It is designed to compete directly with OpenAI’s ChatGPT and Google’s Gemini. Musk claimed during the Grok 3 demonstration that it had more capabilities than Grok 2. Today is the first day that Premium Plus customers on X will have access to the rollout.

“All you need to know to understand which company will win a technology competition is look at the first and second derivatives of the rate of innovation,” Musk said on the X.

Those who want early access can sign up for Premium Plus. In addition, xAI is launching a new membership tier named Super Grok for loyal customers who want early access to updates and access to premium features. The Grok app and the brand-new website, grok.com, will both offer this package.

When compared to other AI models, xAI’s Grok 3 performs better. Grok 3 Mini, a smaller version, is still holding its own at the top level.

“At xAI, we believe that having the best pre-training model is not enough to create the best AI. The best AI needs to think like a human. If you’re using Grok 3, you may notice improvements almost every day because we are constantly working on enhancing the model. In fact, you might even see changes within 24 hours,” they said.

When developing AI, the xAI team stressed the significance of using first-principles reasoning, self-criticism, verification, and backtracking.

“You need to consider all possible solutions, self-critique, verify them, backtrack, and think from first principles. This is a crucial skill. We believe that by taking the best pre-trained model and further training it with reinforcement learning, we can enhance its reasoning abilities. This allows the model to improve significantly and scale, not just during training but also during testing,” the xAI team said.
