Gemini 3

Google DeepMind Institute researchers Rohin Shah and Anca Dragan argue that visible chain-of-thought reasoning is a key safety mechanism for catching deceptive AI behavior, but say OpenAI's GPT-6 Astra system card already shows a significant drop in how well that reasoning can be monitored.

Google DeepMind has upgraded its Co-Scientist system from a hypothesis generator into a closed-loop research partner that plans experiments, controls lab equipment, and writes manuscripts. Built on Gemini 3 models, the system cut fabricated-result rates from 46% to 4% using new verification modules, according to Google.
