The Geometry Challenge: Bridging Vision & Reasoning
Diagram-grounded geometry problem solving is a critical benchmark for multimodal large language models (MLLMs), yet the optimal design of agentic AI systems remains a key question. This study systematically compares single-agent and multi-agent pipelines to address whether explicit task decomposition enhances reasoning in zero-shot settings.
Traditional symbolic methods offer interpretability but lack flexibility, while neural models are adaptable but prone to errors. Neuro-symbolic systems aim to balance these, often requiring manual inputs. The core challenge is to enable VLMs and LLMs to collaborate effectively without task-specific supervision.

Quantifying Agentic Advantage
The research systematically benchmarks single-agent and multi-agent pipelines across four diverse visual math benchmarks: Geometry3K, MathVerse, OlympiadBench, and We-Math. Results reveal a consistent benefit for open-source models when adopting a multi-agent approach, demonstrating significant performance gains.
For instance, Qwen-2.5-VL (7B) saw a +6.8% improvement on Geometry3K and a +9.4% gain on OlympiadBench in multi-agent mode. Similarly, the 32B variant of Qwen-2.5-VL achieved a +3.3% gain on Geometry3K and a +6.67% gain on OlympiadBench.
While closed-source models like Gemini-2.0-Flash generally perform better in single-agent mode on classic benchmarks, multi-agent yields modest improvements on newer datasets like We-Math, suggesting a role for decomposition even in highly capable systems for less familiar tasks.
| Model (Benchmark) | Single-Agent Accuracy | Multi-Agent Accuracy | Performance Change (MA vs SA) |
|---|---|---|---|
| Qwen-2.5-VL 7B (Geometry3K) | 53.24% | 60.07% | +6.8% |
| Qwen-2.5-VL 32B (OlympiadBench) | 57.89% | 64.56% | +6.67% |
| Gemini-2.0-Flash (Geometry3K) | 85.19% | 83.86% | -1.3% |
| Gemini-2.0-Flash (We-Math) | 61.16% | 62.90% | +1.74% |

Understanding Agentic Dynamics
The effectiveness of multi-agent decomposition is not universally optimal but hinges on key factors such as model capacity, literal quality from the Interpreter Agent, and the specific benchmark characteristics.
A predicate alignment analysis confirmed that higher quality Interpreter-generated literals (e.g., Gemini's 0.849 average cosine similarity) directly correlate with superior downstream Solver performance. Weak Interpreters bottleneck the pipeline, while strong ones unlock the Solver's full potential.
For smaller open-source models, decomposition can sometimes introduce noise or over-constraining predicates, leading to performance drops on certain datasets (e.g., Qwen-2.5-VL 7B on MathVerse). Conversely, for highly optimized proprietary systems, explicit structure through multi-agent design can prevent drifting into inconsistent thought chains, especially on novel benchmarks where contamination is less likely.
Qualitative Insight: Recursive Self-Doubt in AI Reasoning
During complex problem-solving, models can exhibit phenomena like recursive self-doubt. In challenging cases (e.g., from MathVerse), the Solver (Qwen) detected ambiguities or contradictions between different pieces of problem information (e.g., explicit angles vs. bearing statements).
This led the AI to engage in multiple re-evaluation cycles, questioning its initial assumptions and calculations. While indicative of an advanced reasoning process, these loops sometimes highlighted underlying inconsistencies in the problem statement itself or led to protracted attempts to reconcile conflicting data, occasionally failing to converge on a correct answer without external cues (like multiple-choice options).
This illustrates the importance of robust literal generation and the potential for agentic systems to expose ambiguities, even if they struggle to definitively resolve them without clearer input or adaptive strategies.
Limitations & Future Directions
The study notes limitations including its zero-shot setting (no fine-tuning), fixed prompting, and limited model scope. Future work could explore adaptive prompting, alternative literal extraction strategies, and full-precision systems to further understand when agentic decomposition is most effective and how it can be optimized.
Implementing Agentic AI: Key Considerations
The findings offer crucial insights for enterprises looking to leverage multi-agent AI for complex reasoning tasks. The decision between single-agent and multi-agent architectures is not one-size-fits-all but requires strategic evaluation:
- For open-source models, especially at medium scale or on harder, multi-step problems, a multi-agent pipeline with a strong Interpreter Agent consistently enhances performance by providing explicit structure and reducing ambiguity.
- For highly optimized proprietary systems, a single-agent approach often remains superior on well-established benchmarks due to tightly coupled perception and reasoning. However, multi-agent decomposition can still offer modest gains on newer, less contaminated datasets, aiding in robustness.
- Literal quality is paramount. Investing in advanced VLM capabilities for accurate and comprehensive predicate generation is critical for multi-agent success.
- Develop adaptive strategies that dynamically select between single-agent and multi-agent configurations based on the specific task, model capacity, and observed input characteristics to maximize efficiency and accuracy.
- Consider the cost-benefit trade-off. While multi-agent offers benefits, its overhead must be weighed against the performance gains, particularly for closed-source models where single-agent performance is already high.
