Google co-founder Sergey Brin says AI models are helping build its own successors

Google co-founder Sergey Brin has revealed that the company’s artificial intelligence (AI) development is accelerating rapidly, with current models now directly being developed by both humans and AI. He explained that current internal AI models are collaborating with company researchers to design and train their own successors, essentially signaling that there will be no slowing down in the race for advanced systems. Speaking during a roundtable discussion focused on the development of Google’s new Gemini 4 model Argon, Brin explained that Google is approaching a critical technical threshold known in computer science as recursive self-improvement (RSI).Under an RSI framework, an AI model assists in engineering (or writing) superior algorithms, codebases and architectures, creating an automated flywheel effect – a concept of several small, consistent efforts combining over time to build self-sustaining momentum – that dramatically shortens the lifecycle required to ship subsequent generations.“Our researchers and the model work hand in…
