Nvidia CEO Jensen Huang declared that artificial general intelligence has arrived with OpenAI's GPT-6 Astra, trained on over 100,000 Nvidia Grace Blackwell systems. AI critic Gary Marcus pushed back, arguing there's no evidence or agreed definition. The debate highlights fundamental questions about what constitutes AGI.

Jensen Huang Declares AGI Has Arrived

Nvidia CEO Jensen Huang made a bold declaration on Sunday, stating that artificial general intelligence has arrived with the launch of OpenAI's GPT-6 Astra

1

. Taking to X, Huang congratulated the OpenAI team and traced the rapid evolution of AI models over just four years: "From ChatGPT to o1 to Astra in 4 years. AGI has arrived"

2

. OpenAI President Greg Brockman echoed this sentiment, describing the launch as the beginning of the AGI era

3

. OpenAI has positioned GPT-6 Astra as its most intelligent and aligned AI model, claiming it scored 98% on FrontierMath Tier 4, 99.9% on ARC-AGI-3, and 100% on ExploitBench

1

. The model demonstrates capabilities across computer use, software engineering, cybersecurity, science, and professional work

Massive Computing Infrastructure Behind Astra

Huang revealed that OpenAI's GPT-6 Astra was trained using more than 100,000 Nvidia Grace Blackwell NVLink72 systems

1

. This staggering computational power underscores the vast resources required to develop frontier AI models. Huang added that another 400,000 Nvidia GPUs are coming online

2

, signaling continued expansion in AI infrastructure. The scale of hardware deployment reflects the intense competition among tech companies to achieve AI advancements. Nvidia shares closed at $230.36 on Friday, up 0.84%, with the stock maintaining positive price-trend ratings across short-, medium-, and long-term periods according to Benzinga Edge Rankings

Gary Marcus Challenges AGI Claims

AI researcher and NYU professor Gary Marcus swiftly disputed Huang's declaration, stating it was "sad to see Jensen claim that AGI has arrived, with no evidence and no definitions"

1

. Marcus, a longtime AI critic, argued that OpenAI's GPT-6 Astra still falls short under conventional definitions of artificial general intelligence. He warned that declaring victory without first establishing what AGI means "simply muddies the waters"

1

. The pushback highlights a fundamental problem in the AI industry: the lack of a universally accepted definition or test for AGI

3

. According to Stanford's Institute for Human-Centered AI, AGI refers to AI that can learn, reason, and apply knowledge across a broad range of tasks at a human level or beyond, unlike narrow AI that operates within specific domains

.

Huang's Evolving AGI Definition

This isn't the first time Nvidia CEO Jensen Huang has claimed AGI has arrived. In March 2025, during an appearance on the Lex Fridman Podcast, Huang stated, "I think we've achieved AGI"

1

. His definition doesn't hinge on whether the AI business remains successful long-term. Huang argued that an AI model creating a viral app, generating $1 billion in revenue, and eventually shutting down could still qualify as AGI—similar to short-lived dot-com companies that demonstrated real commercial success

1

. At the 2023 New York Times DealBook Summit, Huang had predicted AGI could become reality within five years, defining it as a computer or software system capable of performing tasks requiring human-level intelligence

1

.

Industry Debate Over Human-Level General Intelligence

The disagreement between Huang and Marcus reflects broader tensions in the AI community about what constitutes human-level general intelligence. Companies developing frontier models increasingly argue their systems are approaching or have reached AGI, while several researchers remain skeptical about whether current AI models truly possess general intelligence

3

. The concept remains debated because ongoing safety and ethical concerns persist alongside the absence of agreed-upon benchmarks

1

. Watch for how regulatory bodies respond to these AGI claims and whether the industry can establish standardized definitions and testing frameworks. The stakes are high: companies with vested interests in declaring AGI may be motivated by competitive positioning rather than scientific consensus, potentially shaping public perception and policy decisions around AI capabilities and risks.
