In one line

AURA 2.0 creates a streaming video AI that can initiate conversations and use tools without waiting for a direct user query.

Current AI assistants wait silently for a command, even when watching a live video. They offer no comment on unfolding events unless a user specifically asks a question.

AURA 2.0 processes video frame-by-frame. It can detect meaningful moments in the stream and begin a conversation on its own, use internet tools to gather more context, and visually highlight objects it talks about.

Evaluations show it achieves leading performance on standard benchmarks. Targeted tests confirm it starts useful conversations, improves answer accuracy through tool use, and accurately points to objects, moving beyond purely reactive interaction.
