Google co-founder Sergey Brin hasn’t stayed fully retired. He’s diving back in, rallying a DeepMind strike team to fix glaring holes in the company’s AI coding tools. The target? Anthropic’s Claude models, which Google’s own engineers say outpace Gemini in code generation. This isn’t casual involvement. Brin penned an internal memo to DeepMind staff. “To win the final sprint, we must urgently bridge the gap in agentic execution and turn our models into primary developers,” he wrote, according to Android Authority . Every Gemini engineer now faces mandates to use internal agents for complex tasks. No opt-outs. The team pulls in top talent. Sebastian Borgeaud, DeepMind research engineer who once led pretraining efforts, heads it. Koray Kavukcuoglu, DeepMind’s CTO, chips in. Brin oversees the whole push. Their mission: craft internal coding models trained on Google’s vast proprietary codebase—models too sensitive for public release. Why the scramble? Google lags rivals badly.…
