Build a Vision AI Agent with Gemini 3 in < 3 Minutes
Blog post from Stream
Vision Agents has introduced support for Google's Gemini 3 models within its open-source Python framework, enabling the creation of real-time voice and video AI applications. A short video demonstration showcases how to develop a vision-enabled voice agent capable of screen or webcam analysis, reasoning with Gemini 3 Pro Preview, and engaging in natural conversation using only Python. The process involves installing Vision Agents alongside the Gemini plugin, using the gemini-3-pro-preview as the LLM, and building a live video-call agent that can describe on-screen content in real time. Users are guided through setting up a project, installing necessary plugins, and modifying a Python script to create an AI agent that observes and responds to camera feed inputs. The framework facilitates interactive voice and video experiences with enhanced reasoning and multimodal understanding without needing complex frontend setups, encouraging users to explore its capabilities with minimal setup time.
