Methods

​

run()

def run(self, task: str)

• task (str): Task containing the response to evaluate

​

Usage Examples

​

Basic Evaluation

from swarms import CouncilAsAJudge

# Create council
council = CouncilAsAJudge(
    name="Response-Evaluator",
    output_type="final"
)

# Evaluate a response
task_response = """
Question: Explain how neural networks work.

Response: Neural networks are computational models inspired by the human brain. 
They consist of layers of interconnected nodes (neurons) that process information. 
Each connection has a weight that adjusts during training. The network learns by 
adjusting these weights to minimize error between predictions and actual outputs.
This process is called backpropagation.
"""

evaluation = council.run(task_response)
print(evaluation)

​

Custom Model Configuration

# Use specific models for evaluation
council = CouncilAsAJudge(
    model_name="claude-sonnet-4-6",  # For judge agents
    aggregation_model_name="claude-sonnet-4-6",  # For final synthesis
    random_model_name=False,  # Don't randomize
    output_type="dict"
)

evaluation = council.run(task_response)

​

With Random Model Diversity

# Use random models for diverse perspectives
council = CouncilAsAJudge(
    random_model_name=True,  # Each judge uses different model
    output_type="final"
)

evaluation = council.run(task_response)

​

Full Conversation History

# Get complete evaluation breakdown
council = CouncilAsAJudge(
    output_type="dict-all-except-first"
)

full_evaluation = council.run(task_response)

# Access individual dimension evaluations
for message in full_evaluation:
    print(f"\n{message['role']}:")
    print(message['content'][:200])

​

Specific Judge Model

# Use Claude for all judge agents
council = CouncilAsAJudge(
    judge_agent_model_name="anthropic/claude-sonnet-4-5",
    aggregation_model_name="claude-sonnet-4-6",
    random_model_name=False
)

evaluation = council.run(task_response)

​

Evaluation Report Structure

​

1. Executive Summary

• Key strengths and weaknesses
• Critical issues requiring immediate attention
• Overall assessment

​

2. Detailed Analysis

• Cross-dimensional patterns
• Specific examples and their implications
• Technical impact assessment

​

3. Recommendations

• Prioritized improvement areas
• Specific technical suggestions
• Implementation considerations

​

Dimension-Specific Evaluations

1. Specific Observations: References exact parts of the response
2. Impact Analysis: Explains how issues affect quality
3. Concrete Examples: Demonstrates strengths and weaknesses
4. Improvement Suggestions: Actionable recommendations

​

Parallel Execution

• Workers: Automatically configured based on CPU count (75% of cores)
• Concurrency: All 6 dimensions evaluated in parallel
• Error Handling: Individual dimension failures don’t stop other evaluations
• Performance: Significantly faster than sequential evaluation

​

Example Output

evaluation = council.run(task_response)

# Output structure (when output_type="dict"):
[
    {"role": "User", "content": "Task response..."},
    {"role": "accuracy_judge", "content": "Accuracy analysis..."},
    {"role": "helpfulness_judge", "content": "Helpfulness analysis..."},

​

Best Practices

1. Output Type Selection:
   • Use "final" for quick summary reports
   • Use "dict" to analyze individual dimension evaluations
   • Use "json" for integration with other systems
2. Model Selection:
   • Enable random_model_name=True for diverse perspectives
   • Use stronger models (GPT-4, Claude) for critical evaluations
   • Use faster models (GPT-4o-mini) for development/testing
3. Performance:
   • Council auto-configures workers based on CPU count
   • Consider cache_size for repeated similar evaluations
   • Monitor costs when using multiple premium models
4. Integration:
   • Parse the aggregated report for actionable insights
   • Use dimension-specific feedback for targeted improvements
   • Store evaluations for tracking quality over time
