Vision Agents is an open-source Video AI framework for building real-time voice and video applications built and maintained by the team at Stream. It ships with Stream Video as its default low-latency transport, powered by our global edge network. The framework is edge/transport agnostic meaning developers can also bring any edge layer they like.

​
