Grok-4 redefines the landscape of artificial intelligence, emerging as a pillar of unmatched performance. This innovation from xAI, founded by Elon Musk, transcends the established standards of traditional benchmarks. *Superior results compared to the models from OpenAI*, Anthropic, and Google DeepMind testify to a significant advancement.
The focus on reasoning gives Grok-4 superiority in complex tasks. *The parallel orchestrated capabilities of Grok-4 Heavy* offer a new perspective on problem-solving. The stakes of this technological feat reveal an unprecedented potential for innovation in the field of AI.
Grok-4: Performance Revolution in Artificial Intelligence
The Grok-4 model, developed by the start-up xAI founded by Elon Musk, has recently surpassed the former leader, o3-pro from OpenAI, during benchmarks. This major advancement is the result of an intensification of research on complex reasoning.
Focus on Reasoning
xAI has chosen to concentrate its efforts on reasoning, as opposed to generalist models. Grok-4 specializes in tasks requiring sophisticated thinking and advanced logic. The focus has been on reinforcement learning, with investments such as the utilization of 200,000 GPUs from the Colossus supercomputer.
Remarkable Benchmark Performances
This model has set impressive records on several benchmarks. On the PhD-level test, Humanities Last Exam, Grok-4 solves nearly 26.9% of the questions in standard mode and 45% with its Heavy version. These results place it squarely on par with post-doctoral research. Nowhere else could a human hope to achieve even 5% success in this exam.
In mathematics, Grok-4 achieves a perfect score of 100% on the AIME25, surpassing the 98.4% score of o3. On HMMT25, it also distinguishes itself with 96.7% compared to Claude 4 Opus’s 82.5%.
New Records in Fluid Intelligence
Grok-4 stands out particularly on the ARC-AGI test, becoming the first public model to cross the 10% accuracy threshold with 15.9%. Greg Kamradt, president of the ARC Prize, confirmed this exceptional performance. The previous score was around 8% with Claude Opus 4.
Acknowledging Limitations
Although Grok-4 is at the forefront of reasoning, some of its abilities raise questions. Its multimodal performances remain basic. Elon Musk himself acknowledged that this model was partially blind and that its understanding of images needed improvement.
Regarding programming, Grok-4 shows mixed results. On the LiveCodeBench test, it records a score of 79.4%, aligning with Gemini 2.5 Pro and slightly below o3.
Pricing and Subscriptions
Grok-4 is available to the general public through the SuperGrok subscription at $30 per month. The SuperGrok Heavy subscription, at $300 per month, grants access to the multi-agent version. This pricing positions xAI as one of the most expensive AI providers.
For now, the Grok API is also accessible, although pricing remains to be determined.
Future Perspectives
xAI envisions an ambitious timetable for the future. A specialized coding model is scheduled for August, followed by a multimodal agent in September and a video generation model in October. The competition remains fierce, with other players like Claude and Google actively developing their own models.
