Igor Babuschkin Departs xAI to Launch Venture Capital Firm
Babuschkin, who played a pivotal role in building xAI into a leading AI model developer, is now focusing on supporting AI safety research and backing startups that aim to advance humanity. His decision to launch Babuschkin Ventures was inspired by discussions with Max Tegmark, founder of the Future of Life Institute, about the safe development of AI systems.
The departure follows a series of controversies at xAI, including issues with its AI chatbot Grok. Despite these challenges, Babuschkin expressed fond memories of his time at xAI and the lessons learned from working closely with Elon Musk. Musk also acknowledged Babuschkin's contributions to xAI in a post on X.We hope you enjoyed this article

Tensordyne Napier: What If One Rack Could Do the Work of Nine?
Tensordyne
This Tensordyne whitepaper presents Napier, an inference-focused AI processor and rack-scale system based on the company’s TDN Math logarithmic number system. It examines infrastructure requirements for large mixture-of-experts and agentic models, compares major inference architecture approaches, and details the TDN AIP processor, TDN72 pod, TDN Link fabric, and Napier Ultra configuration. The paper reports simulation-based performance, cost, and accuracy-validation results, including Tensordyne’s projected comparison of one Napier rack with a nine-rack Nvidia Rubin plus Groq deployment; the chip is reported as taped out and in fabrication.
