What Brin said
Speaking at a roundtable on Gemini 4 Argon, Google cofounder Sergey Brin said the company is "starting to get onto that RSI treadmill" — recursive self-improvement. According to Business Insider, Brin pointed to the Flash models Google released before Gemini 4 as evidence of the shift.
What it means
Brin's comments suggest that AI models are now helping researchers build the next generation of models. That feeds into a long-running debate about whether models could accelerate their own development, which some experts see as a safety risk.
Safety debate
Recursive self-improvement is one of the most closely watched topics in AI safety. Brin's remark was read as a concrete sign of how far Google has moved in this area.
