Elon Musk Unveils Grok 3, Claiming the World’s Most Powerful AI Model
The article details the launch of Grok 3 by Elon Musk’s xAI, highlighting its massive GPU infrastructure, benchmark dominance over GPT‑4o, multiple model variants, pricing for Premium+ users, upcoming API and voice features, and the team’s plan to open‑source Grok 2 once the new model stabilises.
On Monday, Elon Musk and three other xAI members presented a live demo of Grok 3, the newest large‑language model from xAI, positioning it alongside OpenAI’s GPT, Google’s Gemini and the recently released DeepSeek models.
Musk explained that the name “Grok” comes from the sci‑fi novel Stranger in a Strange Land , where it means a deep, comprehensive understanding. He described Grok 3 as “the smartest AI on Earth” that pursues truth even when it conflicts with political correctness.
xAI claims Grok 3 is 10–15× more powerful than Grok 2, running on the Colossus supercomputer with 100 000 Nvidia H100 GPUs and consuming roughly 200 million GPU‑hours during training.
According to xAI’s benchmark data, Grok 3 achieved an ELO score above 1400 on the Chatbot Arena leaderboard, surpassing GPT‑4o (1385) and DeepSeek‑R1 (1361). It also outperformed GPT‑4o on the AIME math‑question set and the GPQA physics/chemistry/biology suite.
Four model variants are offered: Grok 3, Grok 3 Mini (faster but slightly less accurate), Grok 3 Reasoning and Grok 3 Mini Reasoning, the latter two designed for deeper “thinking” similar to OpenAI’s o3‑mini, DeepSeek‑R1 and Gemini‑2 Flash Thinking.
During the demo, the team showcased Grok 3’s ability to generate a simple game that blends Tetris and Bejeweled mechanics, hinting at xAI’s plan to launch an AI‑driven game studio.
Rapid progress is emphasized: after just 18 months, Grok 2 already exceeds GPT‑4 on baseline metrics, and Grok’s development curve is steeper than OpenAI’s 2019‑2024 trajectory.
Grok 3 is now available to Premium+ users on the X platform for $50 per month, with a forthcoming SuperGrok subscription tier for higher‑level access. The model can be accessed via the Grok iOS app and the Grok.com website, with an Android release planned. An API paired with a “DeepSearch” feature and a voice‑interaction mode are slated for release in the coming weeks.
xAI also reiterated its open‑source strategy: once Grok 3 reaches maturity, Grok 2 will be open‑sourced within a few months.
