The authors built MM-VeriTools by benchmarking candidate methods for textual fact-checking, visual forensics and image-text consistency, retaining the strongest candidates and exposing them through a common calling interface.
Reinforcement learning teaches an agent to verify mixed-source multimodal misinformation
MM-VeriAgent learns sample-specific use of textual, visual and cross-modal verification tools while avoiding explicit tool search at inference time.
