# Agent Judge # Agent Judge
The AgentJudge is a specialized agent designed to evaluate and judge outputs from other agents or systems. It acts as a quality control mechanism, providing objective assessments and feedback on various types of content, decisions, or outputs. The AgentJudge is a specialized agent designed to evaluate and judge outputs from other agents or systems. It acts as a quality control mechanism, providing objective assessments and feedback on various types of content, decisions, or outputs. This implementation is based on the research paper "Agents as Judges: Using LLMs to Evaluate LLMs".
## Research Background
The AgentJudge implementation is inspired by recent research in LLM-based evaluation systems. Key findings from the research include:
- LLMs can effectively evaluate other LLM outputs with high accuracy
- Multi-agent evaluation systems can provide more reliable assessments
- Structured evaluation criteria improve consistency
- Context-aware evaluation leads to better results

# Initialize the judge
judge = AgentJudge(
model_name="gpt-4o",
max_loops=1
)
judge = AgentJudge(model_name="gpt-4o", max_loops=1) # Example outputs to evaluate

## Tips for Implementation ## Troubleshooting
### Common Issues
??? question "Evaluation Inconsistencies"
If you notice inconsistent evaluations:
1. Check the evaluation criteria
2. Verify the model configuration
3. Review the input format
??? question "Performance Issues"
For slow evaluations:
1. Start with simple evaluation tasks and gradually increase complexity 1. Reduce max_loops
2. Optimize batch size
3. Consider model selection
2. Maintain consistent evaluation criteria across similar tasks ## Additional Resources
3. Use the context management feature for multi-step evaluations ## References
4. Implement proper error handling and logging 1. "Agent-as-a-Judge: Evaluate Agents with Agents" - [Paper Link](https://arxiv.org/abs/2410.10934)
