Elon Musk recently claimed that Grok 4 outperforms GPT-5, sparking discussions among AI enthusiasts. This article examines the key points from that assertion and compares the two models based on benchmarks, capabilities, and practical use.
Musk’s Claim and the Benchmark Evidence
Musk stated that Grok 4 was smarter than GPT-5 in certain tests. He pointed to the ARC-AGI benchmark, which measures abstract reasoning. In ARC-AGI-2, Grok 4 scored 15.9-16%, nearly double GPT-5’s 9.9%. In ARC-AGI-1, Grok 4 achieved 66.7% versus GPT-5’s 65.7%. These results suggest Grok 4 has an edge in complex problem-solving.
For math tasks, Grok 4 Heavy scored 100% on AIME 2025, while GPT-5 reached 94.6%. Though both perform well, Grok 4’s perfect score highlights its strength in this area.
Key Differences in Model Design
Grok 4 uses a multi-agent system where AI agents collaborate on queries, using more computational resources. Its features include a 256K token context window for API use and real-time integration with X for current data.
GPT-5 employs a smart router that switches between specialized models based on the task. It offers a 400K token context window, advanced multimodal support for text and images, and 45% fewer errors than its predecessor.
- Context window: Grok 4 has 256K tokens (API); GPT-5 has 400K tokens.
- Real-time access: Grok 4 integrates with X; GPT-5 focuses on multimodal capabilities.
- Error reduction: GPT-5 shows improvements in accuracy.
Cost and Accessibility Factors
For users in India, pricing matters. Grok 4 costs 250 rupees per 1M input tokens and 1,250 rupees per 1M output tokens, with a SuperGrok subscription at 25,000 rupees per month. GPT-5 is cheaper at 105 rupees per 1M input tokens and 835 rupees per 1M output tokens, with ChatGPT Plus at 1,670 rupees per month.
GPT-5 is more accessible, available to all users including free tiers, and integrated with Microsoft platforms. Grok 4 requires a premium subscription but offers API access for developers.
Performance in Content Creation
Both models aid content creators. Grok 4 excels in video script writing with real-time trending topics and social media insights from X. It uses multi-agent reasoning for in-depth research.
GPT-5 stands out in health and science content due to its accuracy and reduced errors. It handles image analysis better, making it suitable for diverse content types.
In code generation, Grok 4 performs well in reasoning, while GPT-5 offers reliable debugging for larger projects.
| Feature | Grok 4 Strength | GPT-5 Advantage |
|---|---|---|
| Research | Multi-agent collaboration | Factual accuracy |
| Real-time data | X integration | Ecosystem compatibility |
| Cost | Premium performance | Budget-friendly access |
Expert Views and Future Plans
Industry leaders see this rivalry as positive. Musk plans to launch Grok 5 by the end of 2025, with capabilities for inventing new technologies by 2026.
OpenAI is developing three GPT-5 variants and expanding multimodal features like video processing while focusing on safety.
Which Model to Choose?
Choose Grok 4 for cutting-edge reasoning and real-time insights. Opt for GPT-5 if you need cost-effective options and broad integration.
