Evaluating Multimodal Commercial and Open-Source LLMs for Dynamical Astronomy
Traditional machine learning methods often struggle with the complexity and ambiguity of classifying resonant arguments from astronomical images, requiring extensive task-specific training and manual expert inspection. This study introduces multimodal Large Language Models (LLMs) as a powerful zero-shot solution, capable of analyzing visual patterns in resonant arguments without prior training, offering a scalable and efficient alternative.
Executive Impact & Key Findings
Our evaluation reveals that LLMs can achieve high accuracy in classifying resonant behaviors, significantly reducing the need for costly and time-consuming manual processes. Even smaller, locally deployable models demonstrate practical utility, democratizing access to advanced astronomical analysis tools.

The Hurdles of Resonant Argument Classification
Traditional machine learning and deterministic methods face significant difficulties in identifying complex, ambiguous resonant arguments from astronomical images. These challenges arise in densely populated regions of phase space where multiple resonances overlap, leading to transient captures, resonance sticking, and noisy behaviors. Crucially, these methods are tightly coupled to specific training conditions, requiring extensive retraining or new model development for each unique resonance type or dataset variation. This limitation necessitates labor-intensive manual inspection by experts for challenging cases, making large-scale population studies impractical.
LLMs: A Zero-Shot Solution for Astronomical Classification
Multimodal Large Language Models (LLMs) offer a transformative approach to these challenges by leveraging their zero-shot learning capabilities. Unlike traditional supervised methods, LLMs do not require task-specific training data, enabling them to classify complex visual patterns directly from images based on natural language instructions. This eliminates the need for extensive training datasets and model adaptations, making them highly versatile. The study demonstrates that LLMs can accurately identify libration and circulation from visual patterns, bridging the gap between human expert judgment and automated analysis, even for nuanced resonant arguments.
Constructing a Robust Benchmark and Classification Taxonomy
To systematically evaluate LLMs, a comprehensive benchmark was developed, comprising four datasets: RB-TEST, RB-PILOT, RB-SMALL, and RB-FULL. These datasets include images of mean-motion and secular resonances, covering clear, ambiguous, and transient cases, with both binary and three-class outputs. A detailed classification taxonomy was introduced, categorizing resonant arguments into subtypes like pure libration, slow libration, chaotic behavior, and transient capture. Standardized prompts, including a comprehensive variant for large models and a simplified one for smaller models, ensure fair and reproducible evaluation of LLM performance on these complex astronomical tasks.
Comparative Performance of Commercial and Open-Source LLMs
The study provides a systematic evaluation of various LLMs across three categories: flagship commercial models (e.g., Claude Sonnet, GPT-5, Google Gemini 2.5), large open-source models (e.g., Llama 4 Maverick, Google Gemma 3), and small locally runnable models (e.g., Google Gemma 3 4B/12B). Commercial LLMs consistently achieved near-perfect accuracy on simple cases and high performance on complex ones (up to 94% F1). Open-source models, especially large variants, also showed strong performance, approaching commercial levels on binary tasks (up to 97% F1). Even small, locally deployable models demonstrated practically useful accuracy (up to 89% F1 on full binary tasks), highlighting their potential for cost-effective research without external dependencies.

Key Insight: Democratizing Advanced Astronomical Analysis
Problem:
Traditional machine learning models are tightly coupled to specific training conditions, leading to performance degradation with changing parameters or complex dynamical regimes. This necessitates extensive training, adaptation, and computational resources for each new classification problem, creating a barrier for researchers with limited resources.
Solution:
This study demonstrates that even small, locally runnable open-source LLMs (e.g., Gemma 3 12B) achieve practically useful accuracy (up to 89% F1 on full binary tasks) without specific training. This enables astronomers to perform complex classification tasks on ordinary hardware, breaking dependencies on external services and reducing costs.
Impact:
The availability of performant open-source LLMs democratizes access to high-quality astronomical classification tools, fostering reproducible and cost-effective research globally.
