# The Expert Conductor Prompt: A Comparative Analysis of LLM Reasoning Patterns
## Executive Summary
The "Expert Conductor" prompt represents a significant advancement in prompt engineering, leveraging a structured dialogue between simulated experts to tackle complex problems. This blog post analyzes how three leading large language models—Claude Sonnet 3.7, Gemini 2.5 Pro, and OpenAI o3—respond to this innovative prompt when tasked with developing a benchmarking framework for foundation models in biopharma R&D. Our analysis reveals distinct reasoning patterns, output styles, and capabilities across these models, providing valuable insights for organizations seeking to optimize their prompt engineering strategies for different LLMs.
## Introduction: The Expert Conductor Methodology
The Expert Conductor prompt is designed to simulate a collaborative problem-solving session between domain experts, guided by a facilitator (the "conductor"). This approach leverages several key mechanisms:
1. **Structured reasoning**: The prompt enforces a clear separation between the reasoning process (`<reasoning>` section) and the final solution (`<answer>` section)
2. **Expert dialogue**: The model creates and manages a panel of domain experts who contribute specialized knowledge
3. **Iterative refinement**: The approach encourages drafting, feedback, and revision cycles
4. **Authentic voices**: Experts "speak" in their own authentic styles, creating a natural dialogue
5. **XML-style tags**: The prompt uses structured tags to organize different types of contributions
This methodology aims to overcome common limitations of standard prompting by:
- Encouraging thorough exploration before synthesis
- Reducing premature convergence on solutions
- Enabling multiple perspectives to be considered
- Creating a transparent reasoning trail
When applied to our test case—benchmarking foundation models in biopharma R&D—this approach requires models to demonstrate sophisticated reasoning about a complex, multi-faceted problem at the intersection of AI, pharmaceutical research, and evaluation methodologies.
## Comparative Analysis: Key Differences

Now, let's examine each model's approach in detail.
## Claude Sonnet 3.7: Comprehensive Expert Collaboration
### Expert Selection and Characterization
Sonnet 3.7 assembled an impressive panel of 10 real-world experts, each with specific credentials relevant to the task:
- **Foundation Model Experts**: Daphne Koller (Insitro founder), Andrew Ng (AI pioneer), Demis Hassabis (DeepMind founder)
- **Biopharma R&D Experts**: Janet Woodcock (former FDA director), Bernard Munos (pharmaceutical innovation expert), Hal Barron (R&D leader)
- **Benchmarking Methodologists**: Karim Lakhani, Melissa Haendel, John Wilbanks
- **Implementation Experts**: Vivian Lee, Eric Topol, David Shaywitz
The model demonstrated deep knowledge of each expert's background and expertise, creating authentic voices that reflected their real-world perspectives. For example, Demis Hassabis discusses AlphaFold benchmarking, while Janet Woodcock focuses on regulatory considerations—both aligned with their actual areas of expertise.
### Dialogue Quality and Reasoning Process
Sonnet 3.7's reasoning section featured extensive dialogue between experts, with each contribution building naturally on previous points. The dialogue progressed logically:
1. Initial problem framing by Daphne Koller (defining foundation models in biopharma)
2. Exploration of evaluation challenges from multiple perspectives
3. Framework proposal by Karim Lakhani
4. Detailed contributions from each expert on their specialty areas
5. Draft framework creation
6. Feedback and revision cycles
7. Final refinement with implementation considerations
The model demonstrated sophisticated meta-cognition about the drafting process, explicitly noting when it was synthesizing expert perspectives and creating revisions based on feedback.
### Output Quality
Sonnet 3.7 produced a comprehensive framework with seven dimensions:
1. Foundation Model-Specific Technical Benchmarks
2. Biological Relevance Benchmarks
3. R&D Productivity Impact Benchmarks
4. Data and Implementation Considerations
5. Regulatory and Governance Benchmarks
6. Business Value and ROI Benchmarks
7. Long-term Value and Patient Impact Benchmarks
Each dimension included detailed metrics and considerations. The answer section effectively distilled the extensive reasoning into a well-structured, standalone solution that maintained the depth of the expert discussion while presenting it in an accessible format.
## Gemini 2.5 Pro: Structured Framework Development
### Expert Selection and Characterization
Gemini 2.5 Pro created a smaller panel of four experts, mixing real and fictional personas:
- Dr. Evelyn Reed (fictional): Foundation AI research expert
- Dr. Daphne Koller (real): Computational biology expert
- Dr. Kenji Tanaka (fictional): Translational medicine expert
- Dr. Lena Petrova (fictional): Scientific ML benchmarking expert
The model explicitly acknowledged the fictional nature of some experts. Each expert had a clear role and perspective, though their voices were somewhat less distinctive than in Sonnet 3.7's response.
### Dialogue Quality and Reasoning Process
Gemini's reasoning process was more structured and concise than Sonnet's, following a clear progression:
1. Problem framing and expert introduction
2. Initial dialogue to identify key challenges
3. Exploration of benchmark components
4. Draft framework creation (v1.0)
5. Expert feedback
6. Framework revision (v2.0)
7. Final consensus
The dialogue was focused and efficient, with each expert making substantive contributions. The model used the draft-feedback-revision cycle effectively, though with fewer iterations than Sonnet 3.7.
### Output Quality
Gemini 2.5 Pro produced a well-structured framework organized into three main sections:
1. Core Principles (7 principles including domain relevance, modularity, multimodality)
2. Essential Benchmark Components (5 components including task definition, datasets, metrics)
3. Key R&D Task Areas (4 areas covering the R&D spectrum)
The answer was comprehensive and well-organized, effectively distilling the reasoning section into a practical framework. The output balanced theoretical foundations with implementation considerations, though it was less detailed on specific metrics and implementation steps than Sonnet 3.7's response.
## OpenAI o3: Concise, Actionable Blueprint
### Approach and Structure
OpenAI o3 took a dramatically different approach, departing significantly from the expert dialogue format specified in the prompt. Instead, it produced a concise, highly structured blueprint organized into six sections:
1. Define R&D-Aligned Benchmark Tracks
2. Curate Datasets and Dynamic Evaluation Sets
3. Metrics Beyond Accuracy
4. Implementation Pipeline
5. Continuous Improvement & Community Alignment
6. Expected Pay-offs
The response used tables, bullet points, and numbered lists to present information efficiently, with minimal narrative text.
### Reasoning Process
Notably, o3's response did not include a visible reasoning section or expert dialogue as specified in the prompt. The model appears to have skipped the collaborative expert reasoning process entirely, jumping directly to a final solution. This represents a significant deviation from the prompt's instructions.
### Output Quality
Despite not following the prompt structure, o3's output was remarkably practical and specific:
- It named actual datasets and tools (TDC, MoleculeNet 2.0, YourBench)
- It specified concrete metrics for different tasks
- It included implementation details like "containerised harness triggered on every model revision"
- It proposed governance mechanisms and community engagement strategies
The response was highly actionable, focusing on practical implementation rather than theoretical framework development. It included specific recommendations that could be immediately operationalized, such as keeping "20% of each dataset siloed; rotate yearly to avoid gaming."
## Technical Merits of the Expert Conductor Approach
The Expert Conductor prompt demonstrates several technical advantages as a prompt engineering technique:
1. **Explicit reasoning externalization**: By separating reasoning from the final answer, it encourages models to show their work and avoid jumping to conclusions.
2. **Multi-perspective problem solving**: The expert panel approach naturally encourages consideration of different viewpoints and reduces blind spots.
3. **Structured iteration**: The draft-feedback-revision cycle mimics human collaborative problem-solving and leads to more refined outputs.
4. **Transparency**: The tagged dialogue creates a clear record of how different considerations influenced the final solution.
5. **Knowledge integration**: The approach effectively combines knowledge from multiple domains into a coherent solution.
However, our analysis reveals that models respond to this prompt structure differently, with varying degrees of adherence and effectiveness.
## Key Insights on Model Reasoning Patterns
### Reasoning Depth vs. Conciseness
- **Sonnet 3.7** demonstrated the deepest reasoning, with extensive exploration of multiple dimensions and perspectives. Its approach was thorough but potentially overwhelming in its detail.
- **Gemini 2.5 Pro** balanced depth with structure, providing substantive reasoning while maintaining a clearer organizational framework.
- **OpenAI o3** prioritized conciseness and actionability over visible reasoning, producing a blueprint-style response that focused on implementation rather than theoretical exploration.
### Prompt Adherence
- **Sonnet 3.7** followed the prompt structure meticulously, using all the specified tags and sections.
- **Gemini 2.5 Pro** adhered to the overall structure but used a more streamlined approach to the expert dialogue.
- **OpenAI o3** largely ignored the prompt's structural requirements, creating its own format that emphasized concise, practical guidance.
### Domain Knowledge Integration
- **Sonnet 3.7** demonstrated exceptional domain knowledge across AI, biopharma, and evaluation methodologies, with detailed references to specific concepts in each area.
- **Gemini 2.5 Pro** showed strong domain knowledge with a good balance across areas, though with less specific detail than Sonnet.
- **OpenAI o3** displayed focused domain knowledge with an emphasis on practical tools and datasets, suggesting specialized knowledge of implementation details.
## Practical Applications and Limitations
### When to Use Each Approach
Based on our analysis, here are recommendations for when each model's approach might be most valuable:
- **Sonnet 3.7's approach** is ideal for complex, multifaceted problems requiring deep exploration and consideration of many perspectives. It works well when thoroughness is more important than conciseness, and when the reasoning process itself provides valuable insights.
- **Gemini 2.5 Pro's approach** is well-suited for problems that benefit from structured thinking and clear organization. It balances depth with accessibility and works well when both the reasoning and the solution need to be clearly communicated.
- **OpenAI o3's approach** excels for practical implementation challenges where actionable guidance is more valuable than theoretical exploration. It's ideal when conciseness and specificity are priorities.
### Limitations to Consider
Each approach has potential drawbacks:
- **Sonnet 3.7's extensive reasoning** may be overwhelming for some audiences and could obscure key points in its thoroughness.
- **Gemini 2.5 Pro's balanced approach** might not provide enough depth for the most complex problems or enough specificity for immediate implementation.
- **OpenAI o3's concise blueprint** lacks transparency in its reasoning process and might miss important considerations by prioritizing brevity.
## Conclusion: Implications for Prompt Engineering
Our analysis of how three leading LLMs respond to the Expert Conductor prompt reveals important insights for prompt engineering:
1. **Different models interpret structured prompts differently**. While Sonnet 3.7 followed the expert dialogue structure meticulously, o3 essentially ignored it in favor of a more direct approach. Understanding these tendencies is crucial when designing prompts for specific models.
2. **The Expert Conductor approach is particularly effective for complex, multidimensional problems** that benefit from diverse perspectives and iterative refinement. However, the overhead of managing the expert dialogue may not be worthwhile for simpler tasks.
3. **Consider your priorities when choosing a model and approach**. If you value thorough reasoning and exploration, Sonnet 3.7's approach excels. If you need a balance of depth and structure, Gemini 2.5 Pro's method works well. If you prioritize concise, actionable guidance, o3's blueprint style may be preferable despite its deviation from the prompt structure.
4. **Prompt engineering should adapt to model strengths**. Rather than forcing all models to follow the same rigid structure, consider adapting your prompting approach to leverage each model's natural tendencies and strengths.
The Expert Conductor prompt represents an innovative approach to structured reasoning with LLMs. By understanding how different models respond to this technique, practitioners can make more informed choices about which models and prompting strategies to employ for different types of problems, ultimately leading to more effective AI-assisted problem-solving.
