Researchers present the top-scoring submission to the QANTA 2026 shared challenge at ICML 2026's EMM-QA Workshop, achieving an overall leaderboard score of 0.402 on multimodal quizbowl tasks. The system uses a two-agent architecture: a GPT-4.1-mini-based Tossup agent with confidence calibration and a GPT-4.1-based Bonus agent with structured relational and multimodal reasoning. Notably, the approach avoids retrieval pipelines and model ensembles, relying instead on lightweight task-specific reasoning policies under efficiency constraints. Results suggest that targeted reasoning strategies can be competitive on resource-constrained multimodal QA benchmarks.
