About Stream
Stream ships open-source Vision AI SDK for multi-modal app testing
Stream offers two core infrastructure APIs: real-time chat/messaging for in-app communication, and a new open-source Vision AI SDK for building and testing multi-modal AI applications. The Vision AI SDK supports live-edit-test workflows across modalities, targeting engineering teams iterating on AI features rather than end-user consumers.
