What AI says about VisTA

VisTA is a reinforcement learning framework that enhances visual tool selection in multimodal AI systems by training agents to intelligently choose and use visual tools for complex reasoning. It includes environment setup, training and inference pipelines, and supports datasets such as ChartQA (Geometry3K coming soon) for tool-based reasoning tasks. The project provides evaluation workflows and a citation to the 2025 arXiv paper describing VisTA.
