Google's Gemini Deep Research, OpenAI's GPT-5.2 Fuel AI Agent Race

• Google unveiled an upgraded Gemini Deep Research agent for long-form reasoning and complex analysis, running on Gemini 3 Pro to minimize hallucinations.
• The launch coincided with OpenAI's release of GPT-5.2, intensifying the competition in agentic AI development.
• Google's new agent features an Interactions API for embedding capabilities into enterprise applications and will be integrated into core Google products.
• Google introduced the DeepSearchQA benchmark, where its agent performed well, though OpenAI's GPT-5.2 also claims strong improvements.

Why It Matters: It highlights the escalating AI race between Google and OpenAI for agentic AI dominance.
