Ostris AI Toolkit is a free, open-source all-in-one training suite for diffusion models (image and video), operable via CLI or web GUI. It supports over 10 model architectures (including FLUX.1/2, Wan, SDXL, SD 1.5, Lumina2, Qwen-Image) and relies on aggressive quantization and layer offloading to enable training on consumer-grade GPUs. The toolkit runs locally on Linux, Windows, and experimentally on Apple Silicon, and is actively maintained as a GitHub repository.
