Towards Robust Multi-Modal Reasoning via Model Selection

Zhuosheng Zhang, Aston Zhang, Mu Li

Abstract

We propose a model selection framework for multi-modal reasoning that dynamically selects the most appropriate model based on task characteristics, improving robustness and efficiency.

How this paper contributes to solving the Zone III problem (PASF-PADE)

Dynamic model selection is a Zone III cost-performance optimization. Not every step in an enterprise workflow requires the most capable (and expensive) model. A routing layer that selects the appropriate model based on task complexity and risk level can dramatically reduce costs while maintaining quality where it matters. This is the economic foundation of viable Zone III deployments.

Why AI is not sufficient for Zone III without this

Zone III refers to high-complexity, high-risk, long-running agentic workflows — the class of enterprise AI deployments where a single failure can cascade across hundreds of steps. Standard AI models, trained to predict the next token, are not inherently designed for durable, governed, multi-step execution. This paper addresses one or more of the structural gaps that make Zone III deployments unsafe without explicit architectural intervention.
