VisGym: Diverse, Customizable, Scalable Environments for Multimodal Agents

VisGym is a gymnasium of 17 visually interactive, long-horizon environments for evaluating, diagnosing, and training vision–language models (VLMs) in multi-step visual decision-making across symbolic puzzles, real-image understanding, navigation, and manipulation.

This repository contains model checkpoints described in the paper VisGym: Diverse, Customizable, Scalable Environments for Multimodal Agents.

Description

Modern Vision-Language Models (VLMs) remain poorly characterized in multi-step visual interactions, particularly in how they integrate perception, memory, and action over long horizons. VisGym provides 17 environments for evaluating and training VLMs, offering flexible controls over difficulty, input representation, planning horizon, and feedback. The suite spans symbolic puzzles, real-image understanding, navigation, and manipulation.
