wan-vae-minecraft-352-640

Finetuned AutoencoderKLWan derived from Wan-AI/Wan2.2-TI2V-5B-Diffusers.

The latents in flow-craft/minecraft-latents-352-640-v2 were encoded with this VAE. Part of FlowCraft.

Usage

from diffusers import AutoencoderKLWan
import torch

vae = AutoencoderKLWan.from_pretrained("flow-craft/wan-vae-minecraft-352-640", torch_dtype=torch.float32)

Dataset

• Dataset: Minecraft (OpenAI VPT)
• Training resolution: 352x640 (H×W)

Frames sampled from the Minecraft gameplay videos released by OpenAI's Video Pre-Training project (Video-Pre-Training). Episodes are RGB video; the VAE is trained to reconstruct them independently of actions.

Training

• Last saved step: 51000

Reproduction

• Training script: scripts/finetune_wan_vae.py
• Source commit: 056f3a6172e738c84ef0c0922ac3531a3cf4fbe9

Best metrics

• metric: val/loss
• mode: min
• value: 1.06140953818957
• step: 51000
