Overview

A configuration principle for setting up reward flow-based RL training of video diffusion models with LoRA fine-tuning.

Description

Reward Flow Configuration manages the parameters for training video diffusion models (Wan2.2) using reward-based optimization. Unlike LLM training pipelines, this configuration specifies diffusion-specific settings including model component paths, LoRA rank/target modules, Euler scheduler parameters, and DeepSpeed-based training with diffusion-specific strategy.

Usage

Use when setting up a reward flow pipeline for video diffusion model fine-tuning with face identity preservation or other reward objectives.

Theoretical Basis

Reward flow optimizes diffusion model parameters through the denoising process, backpropagating reward signals through the Euler ODE solver.
