Elon Musk Launches Grok 3 AI Model
Elon Musk and xAI members officially launch Grok 3 to rival OpenAI's GPT-4o and DeepSeek R-1.
It’s official. Grok 3 is here.
On Monday, Elon Musk himself, along with three other xAI members, joined together for a livestreamed presentation of Grok 3.
If it’s your first time hearing of Grok, it’s an AI model developed by xAI to rival OpenAI’s GPT, Google’s Gemini, and the recently launched DeepSeek models.
Musk shared that the word ‘Grok’ came from Robert Heinlein’s sci-fi novel Stranger in a Strange Land. In the book, ‘Grok’ is a term used by a character raised on Mars, meaning to fully and deeply understand something.

Days prior to the launch, Musk dubbed Grok 3 as the “smartest AI on earth.” During the live-streamed presentation, he added, “[It’s a] maximally truth-seeking AI, even if that truth is sometimes at odds with what is politically correct.”
xAI says Grok 3 is 10 to 15 times more powerful than Grok 2. It runs on the Colossus supercomputer, using 100,000 Nvidia H100 GPUs and racking up 200 million GPU-hours for training. With that kind of power, Grok 3 can handle massive datasets fast and accurately, pushing AI computing to a whole new level.
Grok 3 ranks number one on LMSYS’ Chatbot Arena with a big gap and scores impressively on pretraining and reasoning evaluations.
Grok 3 currently has over 1400 ELO score, with Gemini Flash Thinking coming in at second place with 1,385 ELO score.
It’s important to highlight the fact that Grok 3 is the first model ever to score over 1400 on Chatbot Arena and outperforms the best publicly available reasoning models from OpenAI and Google.
Grok 3 Benchmarks
Based on the benchmarks shared by xAI, Grok 3 beats GPT-4o on several comparisons, including AIME (which evaluates a model’s performance on a sampling of math questions) and GPQA (which assesses models using PhD-level physics, biology, and chemistry problems).
