This is the full-parameter BF16 Spatial-Interactor checkpoint based on Qwen/Qwen3-VL-4B-Instruct. It learns local world-state and ego-motion transitions through supervised fine-tuning, then uses On-Policy Distillation (OPD) to integrate successive transitions over long trajectories.
The privileged transition trace is used only during training. At inference, this checkpoint takes the same image/video and question inputs as its base model, with no extra trace, reward model, or teacher branch.

import torch
from transformers import AutoModelForImageTextToText, AutoProcessor
model_id = "kagakouko/Spatial-Interactor-Qwen3-VL-4B"
processor = AutoProcessor.from_pretrained(model_id)
model = AutoModelForImageTextToText.from_pretrained(

)
Use the base model's image/video input format. No privileged trace or additional teacher is needed for inference. Weights, tokenizer, processor, and chat template are included. See the training guide for SFT and OPD.
