Can Grok 4 Heavy’s Surprising Scores Beat OpenAI and Google’s Best Models?
Elon Musk’s xAI has launched two advanced AI models, Grok 4 and Grok 4 Heavy. These models have set impressive new records in the field of artificial intelligence, especially in reasoning and problem-solving. Their performance has surpassed other leading AI systems from OpenAI, Google, and Anthropic, placing xAI at the forefront of AI innovation.
What Are Grok 4 and Grok 4 Heavy?
- Grok 4: A powerful reasoning AI model built to handle complex questions and tasks.
- Grok 4 Heavy: An even larger version, designed to work with many agents at once, solving problems in parallel.
- Both models focus on reasoning, which means they are built to think through problems and offer clear answers.
Key Benchmark Results
ARC-AGI-2 Benchmark
Grok 4 scored 15.9% — the highest ever on this new test. This is double the score of Claude Opus 4 and OpenAI o3. The ARC-AGI-2 measures how well an AI can reason and solve new, unseen problems.
GPQA (Graduate-Level Problem Solving)
- Grok 4: 87.5%
- Grok 4 Heavy: 88.9%
These scores are higher than those from OpenAI, Google, and Anthropic.
AIME 2025 (Math and Logic)
Grok 4 Heavy achieved 100% accuracy. This shows strong performance in high-level math and logic questions.
Humanity’s Last Exam
- Grok 4 Heavy: 44.4%
- Grok 4: 38.6%
For comparison:
- Gemini 2.5 Pro: 26.9%
- OpenAI o3: 24.9%
Both Grok models used tool support, showing their ability to use external resources.
ARC-AGI-1 (Older Benchmark)
Grok 4: 66.7%
Outperformed OpenAI o3-pro and o4-mini.
