·2026.08.23 23:04

Handle image, video, 3D, and audio generation within a single node graph. Build workflows by directly connecting models and parameters without coding. Provides full control over every output desired by visual professionals.

Natively supports the latest open-source models such as Stable Diffusion, Flux, Wan, and HunyuanVideo. Access to closed-source models like Nano Banana and Seedance is possible through partner nodes. Supports local execution on Windows, Linux, and macOS, covering NVIDIA, AMD, Intel, and Apple Silicon GPUs.

More than just a generation tool, this is an engine integrated into production pipelines. Connect workflows to applications via API endpoints. App Mode allows complex workflows to be exposed through a simple UI. Built-in asynchronous queuing, VRAM management, and model offloading features facilitate efficient local execution.

Save and reuse workflows in JSON format. Extend functionality with custom nodes or configure model paths using extra_model_paths.yaml. The core operates offline by default; disabling paid API nodes maintains a fully offline environment without external downloads.
