What is TongFlow - Open-source GenAI studio?
The platform supports a range of input types and operations that allow seamless integration of different AI capabilities. Workflows run locally by default with options to leverage external GPU resources through user-provided tokens, ensuring no mandatory accounts or data sharing. Built under an open license, TongFlow distinguishes itself by treating multiple modalities equally and including built-in combination features rather than relying on extensions. It accommodates various model providers for text tasks and lists specific models for media processing in its documentation. Developers can extend functionality through a plugin system that works across different backends. The same codebase supports desktop applications, self-hosted setups, and optional cloud instances for flexibility in deployment.
