Sergey Brin has been helping to steer Google's AI efforts. Win McNamee/Getty Images Sergey Brin said Google's Gemini models are increasingly helping to build their successors. Recursive self-improvement, or RSI, is the next big race in AI. A Google safety report said a "majority" of code was being produced by AI agents. Google may be approaching a pivotal moment in AI. In a roundtable discussion about the creation of Google's new Gemini 4 model, Argon, company cofounder Sergey Brin said that AI development was accelerating internally and that models are now helping build their successors. This concept, known as recursive self-improvement (RSI), means AI helps build better AI systems, which can set off a flywheel that speeds up the pace of building new models.
