arXiv:2606.11652v1 Announce Type: new Abstract: This paper investigates reinforcement learning (RL) methods for improving tool-calling capabilities in multimodal small language model (SLM) agents. While existing works have explored various reward designs to improve agentic tool-calling ability, these approaches face inherent limitations for SLM training, especially under multimodal scenarios. First, many existing methods evaluate tool use correctness through exact matching against certain ground-truth or predefined formats. However, this assumption is often unsuitable for multimodal tasks, whe
This paper addresses current limitations in training small multimodal AI agents for tool use, a critical area given the rapid advancement and deployment of agentic systems.
Improved tool-calling capabilities in AI agents, especially multimodal ones, will accelerate their ability to autonomously perform complex tasks and integrate with diverse digital and physical environments.
The development of more robust reinforcement learning methods for multimodal agent tool use will make AI agents more reliable and versatile, expanding their application scope.

AI agents will become more proficient in interacting with various digital tools and interfaces, reducing the need for human intervention in complex workflows.
This increased proficiency will lead to a broader adoption of AI agents across industries, potentially automating more white-collar and service-sector tasks.
The enhanced capabilities of small multimodal agents could accelerate the development of more sophisticated, general-purpose AI systems, enabling new forms of human-machine collaboration and economic productivity.
