Abstract: We present ControlLLM, a novel framework that enables large language models
(LLMs) to utilize multi-modal tools for solving complex real-world tasks.
Despite the remarkable performance of LLMs, they still struggle with tool
invocation due to ambiguous user prompts, inaccurate tool selection and
parameterization, and inefficient tool scheduling. To overcome these
challenges, our framework comprises three key components: (1) a task
decomposer that breaks down a complex task into clear subtasks with
well-defined inputs and outputs; (2) a Thoughts-on-Graph (ToG)
paradigm that searches the optimal solution path on a pre-built tool graph,
which specifies the parameter and dependency relations among different tools;
and (3) an execution engine with a rich toolbox that interprets the
solution path and runs the tools efficiently on different computational
devices. We evaluate our framework on diverse tasks involving image, audio, and
video processing, demonstrating its superior accuracy, efficiency, and
versatility compared to existing methods.
