Musk points out OpenAI's Grok 4, claiming it surpassed GPT-5 by two weeks in intelligence upon its release
================================================
In the world of artificial intelligence (AI), a fierce competition is underway between two of the most advanced models: Elon Musk's Grok 4 Heavy and OpenAI's GPT-5.
On February 16, 2025, President Donald Trump declared that America is going to win the AI race, pledging to ensure the U.S. is a leader in developing and regulating AI. This statement came shortly after Elon Musk, CEO of SpaceX and Tesla, announced that his AI model, Grok 4 Heavy, was outperforming OpenAI's newly launched GPT-5 two weeks prior.
Grok 4 Heavy, developed by Musk's company, xAI, is positioned as one of the most advanced AI models, showcasing continuous real-time improvement through reinforcement learning. It excels in high-level benchmarks such as the USAMO 2025 math Olympiad with a leading score of 61.9%. The model boasts a unique feature: it integrates Elon Musk's perspectives contextually in some responses, offering a unique stance on customization.
On the other hand, OpenAI unveiled GPT-5, its most advanced AI model, but detailed performance comparisons remain limited in publicly available data. GPT-5 was launched around the same time Grok 4 became freely accessible, but a definitive, fully objective comparison remains pending due to the lack of published technical benchmarks comparing GPT-5 directly against Grok 4 Heavy, and xAI's lack of published research transparency on their continuous learning claims.
OpenAI CEO Sam Altman described GPT-5 as "like having a team of PhD-level experts in your pocket." He believes that GPT-5 marks a major step towards achieving artificial general intelligence (AGI).
Meanwhile, the federal government is leveraging ChatGPT across its agencies, demonstrating the growing importance of AI in everyday life.
As of August 2025, the race between Grok 4 Heavy and GPT-5 remains open, with both models pushing the boundaries of AI capability. The absence of comprehensive public benchmark comparisons means that the future of AI development is still uncertain, but one thing is clear: the competition is heating up.
