Google’s Gemini 3 Pro faces OpenAI’s GPT-5.2

The AI arms race heated up Thursday as Google and OpenAI unveiled major updates to their flagship models. Google showcased a “reimagined” Gemini Deep Research powered by Gemini 3 Pro, while OpenAI launched GPT-5.2, its most advanced model yet.

Both are vying to dominate agentic AI for developers and enterprise users.

Gemini Deep Research lets developers embed AI research into apps via Google’s new Interactions API.

It handles massive datasets, supports tasks like drug safety and due diligence, and reduces AI hallucinations during multi-step reasoning.

Google plans to integrate it into Search, Finance, NotebookLM, and more, leveraging Gemini 3 Pro as its most factual model.

OpenAI’s GPT-5.2 comes in three versions: Instant for quick tasks like writing and translation, Thinking for more challenging work like coding and analyzing long documents, and Pro for the highest accuracy, while cutting errors by 38%.

OpenAI focuses on enterprise adoption and developer tools, aiming to deliver reliable agentic solutions across real-world tasks. The launch follows CEO Sam Altman’s internal “code red,” triggered by declining ChatGPT traffic and mounting competition from Google.

The battle ahead
Benchmark tests show strong performance for both, signaling a fierce competition that will shape the future of AI-powered research and productivity tools.
