Elon Musk’s AI company xAI just launched Grok-3, a new version of the AI model that powers the Grok AI chatbot. The new AI model was unveiled during a live broadcast on the social media platform formerly known as Twitter, with the creators describing it as the smartest AI in the world.
The AI model comes in two flavors — Grok-3 and Grok-3 mini — and according to figures from xAI, both models perform as well or better than rivals from Google (Gemini), OpenAI (ChatGPT), Anthropic (Claude), and DeepSeek when it comes to math, science, and programming.

Grok-3 also has a new built-in reasoning engine called DeepSearch, which lets you see the AI chatbot’s thought process as it generates answers to your queries.
The AI model was apparently trained for a total of 200 million processor hours on 100,000 Nvidia H100 Tensor Core GPUs. According to one analyst, however, “improvements over the Grok-2 model appear to be too small to justify the enormous resources used to train it.”
Grok-3 is currently being rolled out to Premium+ subscribers on X, with a newly launched SuperGrok subscription tier that has special features as well as chatbot access via the mobile app and grok.com site.
