Reachability Across the NL/PL Boundary: A Taxonomy-Driven Dataflow Model for LLM-Integrated Applications

Zihao Xu, Xiao Cheng, Ruijie Meng +1

LLM API calls have become a standard programming primitive, but they create a program boundary that disrupts traditional dataflow analysis. A runtime value may be inserted into a n…

Rethinking Complexity Metrics for LLM-Integrated Applications: Beyond Source Code

Zihao Xu, Yuekang Li, Gelei Deng +2

LLM-integrated applications blend natural language prompts with program code, and much of their runtime behavior originates in the prompt layer rather than in the code itself. Exis…
