Gemini 2.5 Pro represents a significant step forward in AI model design, combining raw power with refined reasoning capabilities that directly address complex, real-world tasks.

To make sure search engines serve us well, it's helpful to imagine these tools having different roles - whether it's a "librarian" or a "teacher".

Have researchers discovered a new AI 'scaling law'? That's what some buzz on social media suggests — but experts are skeptical.

You can get at Deep Research through the ChatGPT apps for web, desktop, and mobile devices. On the web, as long as you've selected an AI model that supports the feature from the drop-down list in the top left corner, you'll see a Deep research button in the main prompt box.

Google's AI model Gemini is getting even more personal. The company announced this week that enabling a new personalization tool will allow the AI model to reference your search history to enhance and deepen its responses.

Now, Google is also launching a similar initiative, which aims to turn AI into a co-scientist that can accelerate scientific discoveries. The tech giant explains, "The AI co-scientist is a multi-agent AI system that is intended to function as a collaborative tool for scientists."

"As with any early-stage AI product, we won't always get it right," Stein said. "For example, while we aim for AI responses in Search to present information objectively based on what's available on the web, it's possible that some responses may unintentionally appear to take on a persona or reflect a particular opinion."

Chinese tech giant Alibaba said its latest AI reasoning model, QwQ-32B, "rivals cutting-edge reasoning model, e.g., DeepSeek-R1."
