MindZero-gw-asst-Qwen3-VL-8B-Instruct

A MindZero checkpoint trained from Qwen/Qwen3-VL-8B-Instruct with self-supervised reinforcement learning for online proactive assistance in GridWorld environments.

TL;DR

MindZero trains (M)LLMs to perform efficient and robust online mental reasoning without any mental-state annotations. During training, the model is rewarded for generating mental-state hypotheses that maximize the likelihood of observed actions, as estimated by a planner — analogous to model-based ToM reasoning. After training, MindZero internalizes this reasoning into fast single-pass inference.
