Grok 3 Unveiled: xAI’s leap in AI innovation

xAI, led by Elon Musk, has launched Grok 3, claiming it to be the world’s most advanced AI model. Following its live demo, the model has set new AI performance benchmarks—most notably becoming the first to exceed a score of 1400 on Chatbot Arena. Grok 3 outperforms established competitors like OpenAI’s GPT-4o and Google’s Gemini 2 Pro in reasoning, coding, and problem-solving capabilities. The tech community has praised this achievement, particularly noting xAI’s swift progress as a newcomer in the AI field. Within xAI, the model’s development has generated significant excitement, with both team members and industry observers anticipating its future applications and potential to advance AI technology further.

Key Insights from the Grok 3 Video

According to Elon, Grok 3 is an order of magnitude more capable than Grok 2.

The capacity was doubled in 92 days!

Total GPUs: 200K

All of this compute was used to improve Grok — which has lead to Grok 3.

Grok 3’s training was ten times more extensive than Grok 2’s. While its initial pretraining phase concluded in early January, the model continues to undergo training.

Here are the benchmark numbers:

Grok 3 significantly outperforms other models in its category such as Gemini 2 Pro and GPT-4o. Even Grok-3 mini shows to be competitive.

Results of early Grok 3 in the Chatbot Arena (LMSYS)

It reached an Elo score of 1400 which no other model has achieved.

The model score keeps improving.

Grok 3 also has reasoning capabilities too!

The Grok team has been testing these capabilities which they have unlocked using RL.

The model is good, especially in coding.

Grok 3 Reasoning performance:

The results correspond to the beta version of Grok-3 Reasoning.

It outperforms o1 and DeepSeek-R1 when given more test-time compute (allowing it to think longer).

The Grok 3 mini reasoning model is also very capable.

More on DeepSearch:

• the model can think deeply about user intent
• what facts to consider
• how many websites to browse
• it can cross-validate different sources

DeepSearch also exposes the steps that it takes to conduct the search itself.

What others are saying on X:

An early version of Grok-3 (codename “chocolate”) has claimed the #1 spot in Arena!

Grok-3 has achieved two major milestones:

• First model ever to break the 1400 score barrier
• #1 ranking across all categories—an increasingly challenging feat

I was given early access to Grok 3 earlier today, making me I think one of the first few who could run a quick vibe check.

✅ First, Grok 3 clearly has an around state of the art thinking model ("Think" button) and did great out of the box on my Settler's of Catan… pic.twitter.com/qIrUAN1IfD

BREAKING: @xAI early version of Grok-3 (codename “chocolate”) is now #1 in Arena! 🏆

Grok-3 is:
– First-ever model to break 1400 score!
– #1 across all categories, a milestone that keeps getting harder to achieve

Huge congratulations to @xAI on this milestone! View thread 🧵… https://t.co/p8z8lccNd5 pic.twitter.com/hShGy8ZN1o
