Billion-Dollar Bets on RSI; Hard Limits Persist

Both Anthropic and OpenAI made unusually clear statements saying recursive self-improvement is underway at their labs. Researchers including John Schulman identify hard limits. AI can speed up well-specified research but cannot discover new training paradigms. They argue that "thinking alone can't generate new bits." Zhipu AI dedicated 60% of its $5 billion raise to RSI loops. Oriol Vinyals says RSI will happen but will be slow. He argues the real bottlenecks are research taste and reliably evaluating whether self-improvement actually occurred.

The debate sharpened this week. Recursive is a new startup with a $4.65 billion seed round. Founder Richard Socher showed an AI beating humans on optimization tasks in under two days. It also found GPU kernel improvements without CUDA experts. Socher says reward hacking is the core unsolved alignment problem and that AI research could compress from years to weeks.
