xAI Unveils Grok 3: A New AI Model to Rival GPT-4o and Gemini
Elon Musk’s AI company, xAI, has officially launched its latest flagship AI model, Grok 3, on February 17, 2025. This release marks a significant step forward in the competitive AI landscape, positioning Grok 3 as a direct rival to industry leaders like OpenAI’s GPT-4o and Google’s Gemini. Integrated into the Grok app for iOS and web, Grok 3 boasts enhanced capabilities and new features designed for diverse applications.
Grok 3’s Advanced Features: Reasoning, Speed, and DeepSearch
Grok 3 is not just a single model but a family of AI models, including Grok 3 mini for speed and specialized reasoning models like Grok 3 Reasoning and Grok 3 mini Reasoning for complex tasks. These reasoning models excel in mathematics, science, and coding, employing self-checking mechanisms for accuracy. Users can leverage “Big Brain” mode for particularly challenging queries, enhancing the AI’s reasoning capabilities. Furthermore, Grok 3 introduces DeepSearch, a feature that scans the internet and Musk’s social network X to provide concise, abstract answers to user queries, acting as a powerful research assistant.

Outperforming Competitors: Grok 3’s Benchmark Results
xAI claims Grok 3 demonstrates superior performance on key benchmarks. It reportedly outperforms competitors in math (AIME) and PhD-level knowledge in science (GPQA) and shows competitive results in the Chatbot Arena, a crowdsourced evaluation platform. Early benchmarks position Grok 3 as a leader in the AI field, surpassing previous top models.
Computational Power Behind Grok 3: 200,000 GPUs in Memphis Data Center
The development of Grok 3 was enabled by a massive computational infrastructure, including a data center in Memphis equipped with approximately 200,000 GPUs. According to Elon Musk, Grok 3 was trained with “10x” more computing power than Grok 2 and on an expanded dataset, including legal filings. This substantial increase in resources has resulted in a model xAI describes as “an order of magnitude more capable” than its predecessor.
Access and Pricing: How to Try Grok 3
Currently, access to Grok 3 is exclusive to X Premium+ subscribers. A SuperGrok subscription, priced at $30 per month, unlocks additional features like unlimited image generation and expanded reasoning queries. xAI plans to roll out a voice mode within a week and API access for developers in the coming weeks, broadening Grok 3’s accessibility and applications.
Grok 3: Maximally Truth-Seeking or Politically Biased?
Elon Musk has framed Grok as a “maximally truth-seeking” AI, intended to be a politically neutral alternative to mainstream AI systems. However, past versions of Grok have faced criticism regarding potential political biases stemming from its training data. While Musk aims for political neutrality in Grok 3, the extent to which this has been achieved remains to be seen.
