xAI Unveils Grok 4: A Game-Changer in Multimodal AI
xAI launches Grok 4, a powerful multimodal AI model that surpasses graduate-level performance in academics.
Key Points
- • Grok 4 outperforms most graduate students in academic performance according to xAI.
- • The model processes text, images, and voice inputs, integrated into the platform X.
- • Scored 25.4% on Humanity’s Last Exam, outperforming OpenAI's and Google's models.
- • Introduced Grok 4 Heavy for demanding tasks, and SuperGrok Heavy subscription at $300/month.
On July 12, 2025, xAI, the artificial intelligence company founded by Elon Musk, officially launched Grok 4, a multimodal AI model designed to process text, images, and voice inputs. This groundbreaking model is reported to surpass the academic performance of most graduate students and aims to position xAI competitively against major players like OpenAI and Google.
Musk claims that Grok 4 has the capability to address complex, PhD-level questions. However, he also acknowledged that the model still struggles with basic reasoning tasks, suggesting that while it is a significant advancement, it is not infallible. In performance evaluations, specifically an assessment dubbed Humanity’s Last Exam, Grok 4 achieved a score of 25.4%, outperforming OpenAI's o3 and Google’s Gemini 2.5 Pro, which each scored 21%. This marks a notable improvement in the efficacy of xAI’s models relative to its competitors.
In addition to its core capabilities, xAI introduced Grok 4 Heavy, a variant geared toward more demanding tasks, which uses a team-based approach where multiple AI agents tackle the same problem independently before comparing their results for accuracy. This innovation aims to enhance both the reliability and efficiency of problem-solving processes. Furthermore, xAI is offering SuperGrok Heavy, a premium subscription service priced at $300 per month, aimed at users requiring advanced computational capabilities.
This launch represents a significant step for xAI in the evolving landscape of AI technology, where the competition among developers is intensifying. As Musk articulated, the introduction of Grok 4 may be a turning point in the development of multimodal AI, with its advanced capabilities likely to shape future AI applications and benchmarks.
