The public exchange between rival tech CEOs continued this week as Google CEO Sundar Pichai offered a four-word response to Elon Musk’s announcement detailing the substantial advancements in xAI’s next-generation large language model, Grok 4.1. Musk reposted a comprehensive list of improvements for Grok 4.1, concluding his summary with the self-assessment: “Pretty accurate.”Pichai replied simply, “congrats on the progress!”
Grok 4.1 launch: Musk says it offers ‘significant increase in speed and quality’
The new Grok 4.1 model is currently in a limited beta for SuperGrok and Premium+ users and boasts several major improvements over its predecessor:Improved multimodality: Grok 4.1 is claimed to offer improved multimodal vision, fixing “blind spots” in image and video understanding. It can now reliably read text in images, understand charts, follow video action, and interpret internet memes.Reduced hallucination: According to the company, the model saw a 40–50% cut in generating “bullshit answers” on obscure or fast-moving topics, thanks to an extra distillation and reinforcement learning pass.Enhanced speed and context: Inference speed is roughly 28% faster with no quality drop, the company claims, adding that the model now maintains full coherence and accuracy across a native 1 million context window.“Truth-Seeking” calibration: The model is claimed to be less likely to soften politically uncomfortable facts, maintaining a “rigorously factual” tone.Pichai’s congratulatory message follows a recent public exchange regarding the massive financial commitment required to build this new generation of AI.Google recently announced a $40 billion investment in Texas through 2027 to build Cloud and AI infrastructure, including new data centers. Musk, who has relocated his own company headquarters to Texas, responded to that investment, calling the sheer amount of money being spent on AI compute “mind-blowing” while predicting even greater expenditures ahead. Pichai replied by touting Texas’s advantages: “Between abundant sand, plenty of sun and space (literally) to put it in, we can do it :).“
