Coherence Documentation

Coherence is a synthetic data generation platform that helps engineering teams build and test AI systems, particularly LLM integrations. It generates comprehensive test datasets 10x faster than traditional approaches.

Core Features

  • Intelligent Agent Generation: Create tailored golden datasets from context, examples, or system prompts
  • Comprehensive Testing: Evaluate prompts, compare models, and identify edge cases systematically
  • Flexible Data Shaping: Define precise schemas and validation rules for generated outputs
  • Model Evaluation: Compare different LLM performance across consistent test scenarios
  • Version Control: Track dataset evolution and changes over time
  • Collaborative Workspace: Share datasets and testing configurations across teams

Key Use Cases

LLM Prompt Engineering & Optimization

Test and refine prompts at scale by generating diverse test cases. Identify where prompts break down, optimize for edge cases, and validate improvements across large datasets.

Model Selection & Comparison

Evaluate multiple models against consistent test sets to make data-driven decisions about which LLM best fits your use case. Compare performance, cost, and reliability metrics across different models and configurations.

Edge Case Discovery

Automatically generate challenging scenarios that might be missed in manual testing. Our intelligent agent creates variations that help uncover potential failure modes and corner cases in your AI system.

Rapid Prototyping

Quickly validate AI features by generating realistic test data that matches your production scenarios. Iterate faster with immediate feedback on how your changes impact system behavior across different use cases.

Regression Testing

Maintain confidence in your AI systems with automated testing against known scenarios. Track performance over time and catch unintended changes in model behavior as you update prompts or switch models.

Performance Benchmarking

Create standardized test suites to measure and compare system performance. Generate consistent benchmarks for latency, accuracy, and other key metrics across different configurations.
