Vitalik Buterin Says X’s Grok Is Good for Truth

26th December 2025 – Ethereum co-founder Vitalik Buterin believes that Grok, the AI chatbot integrated into Elon Musk’s X, has had a surprisingly positive impact on the platform’s relationship with the truth.

In a post on December 26, Buterin said Grok helps counter political bias by catching users off guard. “The easy ability to call Grok on Twitter is probably the biggest thing after Community Notes that has been positive for the truth-friendliness of this platform,” he wrote.

Importantly, Buterin noted that users can’t predict how Grok will respond. This, he said, is a strength. “I’ve seen many situations where someone calls on Grok expecting their crazy political belief to be confirmed and Grok comes along and rugs them.”

Although he sees Grok as a net positive for public discourse, Buterin admitted there are valid concerns. One of them is how Grok might be influenced by its creator Elon Musk or by certain users who help shape its fine-tuning.

Past Incidents Raise Concerns About Bias

Last month, Grok sparked backlash after it made bizarre claims about Musk’s athleticism and suggested he could have resurrected faster than Jesus Christ. Musk later blamed these responses on “adversarial prompting,” a method used to make AI models produce extreme or nonsensical outputs.

The incident brought renewed focus on the need for AI to remain unbiased, especially as more people rely on it for information. Industry experts, including Aethir CTO Kyle Okamoto, warn that centralized AI models risk institutionalizing bias. If a single company owns and trains the system, it may assert subjective views as fact.

“When the most powerful AI systems are governed by one company, algorithmic bias becomes institutionalized knowledge,” Okamoto said. “At that point, bias stops being a bug. It becomes the logic of the system.”
