Gemini 3's Deep Think mode now live for Ultra-tier subscribers

Google rolled out Deep Think mode for Gemini 3 starting today, accessible only to Ultra-tier subscribers. The feature harnesses parallel processing of distinct reasoning chains to tackle intricate computational problems. Initial benchmarking shows marked improvements across established reasoning assessment standards, notably ARC-AGI-2 and HLE. These tests are commonly used to measure performance on complex logical inference and problem resolution. The feature release strengthens Gemini's reasoning arsenal for its paid user base.
