Gemini 3 Deep Think: Major upgrade for science and research with iterative reasoning rounds

What's new

• Iterative reasoning: Deep Think runs multiple reasoning rounds before formulating answers to complex scientific problems.
• Scientific validation: Developed in collaboration with scientists for real-world challenges — incomplete data, no single correct answer.
• Peer review assistant: Identified a logical flaw in a highly technical math paper that human peer review missed.
• Availability: Google AI Ultra subscribers in the Gemini app; API early access for scientists and enterprise customers.

Why it matters

Google is targeting the research/science segment with Deep Think — an area where OpenAI o1/o3 underperform. Documented results (identifying a peer review error) are a stronger argument than purely synthetic benchmarks.

How to try it

Requires Google AI Ultra subscription. Select Deep Think model in the Gemini app. API early access via Google AI Studio waitlist.
