Elon Musk’s influence on Grok 4 extends beyond his role as xAI’s founder. His commitment to creating an AI that prioritizes truth-seeking over political correctness has shaped Grok’s development from the outset. Musk has been vocal about his concerns with “woke” AI models, criticizing competitors like OpenAI and Google for embedding biases into their systems. He has positioned Grok as a counterpoint, designed to provide raw, unfiltered insights that align with his vision of a “maximally truth-seeking AI.”

However, this approach has not been without controversy. Grok 3 faced criticism for occasionally producing biased or inflammatory responses, such as referencing the “white genocide” conspiracy theory or making politically charged statements. In response, Musk announced plans to retrain Grok to reduce “garbage” in its outputs and align it more closely with a politically neutral stance. Grok 4 is expected to reflect these efforts, with xAI implementing stricter oversight to ensure the model delivers accurate and impartial answers.

Musk’s broader vision for Grok 4 involves using the AI to “rewrite the entire corpus of human knowledge,” adding missing information and correcting errors. This ambitious goal underscores his belief that AI can transform our understanding of the world by providing a clearer, more objective lens on complex issues. While some critics, like AI researcher Gary Marcus, have compared this approach to an “Orwellian dystopia,” Musk’s supporters argue that it’s a necessary step to counter the biases of legacy media and other AI systems.

Performance and Benchmarks: How Grok 4 Stacks Up

xAI claims that Grok 4 outperforms leading models like OpenAI’s GPT-4o, Google’s Gemini, Anthropic’s Claude, and DeepSeek’s V3 in early testing. While Grok 3’s Reasoning Beta model ranked highly on the Artificial Analysis Quality Index, it fell behind OpenAI’s o3 and DeepSeek’s R1 in some areas. Grok 4 aims to close this gap, with xAI’s internal benchmarks suggesting superior performance in math, science, and coding tasks. However, these claims await independent verification, as Musk’s bold assertions about Grok being the “smartest AI on Earth” have raised skepticism in the AI community.
