Example training configurations for the LTX-2 trainer. Each file is a ready-to-run config for one training mode, expressed through the unified flexible strategy (name: "flexible"). Pick the one closest to your use case and adjust paths, dataset, and hyperparameters.

📖 For more information about using each training mode, see Training Modes Guide.
