New benchmark evaluates LLMs for generating Mermaid sequence diagrams

Researchers have introduced MermaidSeqBench, a new benchmark designed to evaluate the ability of large language models to generate Mermaid sequence diagrams from natural language prompts. The benchmark includes 132 human-verified and LLM-augmented samples, assessing aspects like syntax correctness and practical usability. Initial evaluations using LLM judges revealed significant capability gaps among current state-of-the-art models, highlighting the need for improved diagram generation standards for software engineering applications. AI

IMPACT Provides a standardized evaluation for LLM-generated diagrams, crucial for reliable deployment in software engineering.

    MermaidSeqBench: An Evaluation Benchmark for NL-to-Mermaid Sequence Diagram Generation

    arXiv:2511.14967v2 Announce Type: replace-cross Abstract: Large language models (LLMs) have shown great promise in generating structured diagrams from natural language descriptions, particularly Mermaid sequence diagrams for software engineering. However, the lack of existing ben…
