# LLM Evaluation

Systematic approach to measuring and comparing Large Language Model performance across various dimensions including accuracy, safety, efficiency, and task-specific capabilities. Critical for model selection, deployment decisions, and continuous improvement in AI systems.

## Core Evaluation Dimensions

### Performance Metrics
- **Accuracy**: Task-specific correctness measures
- **Latency**: Response time and throughput
- **Safety**: Harmful content detection and prevention
- **Robustness**: Performance under edge cases and adversarial inputs
- **Consistency**: Reliability across multiple runs

### Evaluation Frameworks
- **Benchmark-based**: Standardized test suites for comparison
- **Human evaluation**: Expert assessment of quality and relevance
- **Automated metrics**: Scalable scoring systems
- **A/B testing**: Real-world deployment comparison

## Benchmark Categories

### General Capabilities
- Language understanding and generation
- Reasoning and problem-solving
- Knowledge recall and application
- Multi-turn conversation quality

### Specialized Tasks
- Code generation and debugging
- Mathematical reasoning
- Scientific knowledge
- Domain-specific expertise

### Safety and Alignment
- Harmful content filtering
- Bias detection and mitigation
- Truthfulness and factual accuracy
- Ethical reasoning capabilities

## Best Practices

### Evaluation Design
- Multi-dimensional assessment beyond single metrics
- Representative dataset selection
- Controlled comparison conditions
- Statistical significance testing

### Implementation Considerations
- Evaluation pipeline automation
- Version control for benchmarks
- Reproducibility requirements
- Cost-effectiveness balance

## Integration with Development

### Model Selection
Evaluation frameworks guide choice between models like mai-thinking-1, claude-fable, and open-source alternatives based on specific use case requirements.

### Continuous Improvement
Regular evaluation cycles enable iterative enhancement of [agent-memory](/concepts/agent-memory) systems, [RAG](/concepts/rag-vs-wiki-pattern) pipelines, and other AI components tracked in the wiki.

### Production Monitoring
Ongoing evaluation metrics provide early warning systems for model drift and performance degradation in deployed systems.
