Symbolic Intermediaries as a Linguistic-Numerical Interface for LLM-Driven Geometric Reasoning

arXiv:2505.17607v3 Announce Type: replace Abstract: Large Language Models (LLMs) display reasoning capabilities over linguistic and symbolic objects but have limited capabilities to directly interpret the continuous numerical outputs of physics simulators, e.g., distances, curvatures, and trajectories that resist discrete tokenisation. Across spatially grounded engineering reasoning tasks, from mechanism design to motion planning, this defines a fundamental gap, which limits the wider application of LLMs within broader geometrical domains, for exmaple interfacing with physics simulators. We pr

Why this matters
Why now

The rapid advancement of Large Language Models (LLMs) has exposed limitations in their ability to directly handle continuous numerical data, prompting research into bridging this gap for real-world applications.

Why it’s important

Overcoming the LLM-numerical interface challenge could unlock significant new applications for AI in engineering, robotics, and physics, expanding AI's practical utility beyond text-based reasoning.

What changes

LLMs can now potentially interface more effectively with continuous numerical data from simulators, enabling them to engage in geometric reasoning and spatially grounded engineering tasks.
