Recursive Superintelligence, a four-month-old startup founded by former DeepMind and OpenAI engineers and focused on self-teaching AI, has raised over $500 million from Google Ventures and Nvidia at a $4 billion valuation, the Financial Times reports via Techmeme. The company is betting on meta-learning and recursive self-improvement — the premise that reaching superintelligence requires AI to become the engineer of its own improvements rather than a product of human engineering. The round is among the largest ever for a startup of its age and reflects continued investor appetite for frontier AI labs led by researchers from established organizations.
