Platform Capabilities
Measure everything. Improve continuously.
Automated Testing
Automatically test GenAI systems against auto-generated evaluation datasets and proprietary benchmark datasets across 12+ critical capability domains.
Human-in-the-Loop Evaluation
Industry-leading HiTL evaluation for the highest-complexity test cases. Human reviewers ensure accuracy where automated scoring falls short.
Custom Metrics and Rubrics
Augment industry best-practice rubrics with custom metrics and datasets tailored to your specific domain, use case, and quality bar.
Production Monitoring
Monitor live production traffic to surface quality metrics, anomalies, and alerts. Detect prompts not covered by your evaluation datasets before they cause failures.
Continuous Improvement Loop
Programmatically convert evaluations into actions. Drive RAG optimization and fine-tuning from evaluation findings. Close the loop between measurement and improvement.
Safety and Reliability Testing
Prevent bias, hallucinations, accuracy failures, and harmful outputs. Adversarial robustness testing, red-teaming, and safety evaluation built into every evaluation cycle.
Regression Detection
Track model performance over time. Automatically surface regressions across versions, prompts, and deployment configurations before they reach users.
Cost and Latency Tracking
Monitor cloud costs, token usage, and latency alongside quality metrics. Understand the full operational profile of your GenAI deployment.
Benchmark Leaderboards
Expert-driven private evaluations across coding, mathematical reasoning, multilingual understanding, agentic tool use, visual-language, and adversarial robustness.
Evaluation Domains
Comprehensive coverage across every critical capability.
How It Works
From measurement to improvement, automatically.
01
Define
Set evaluation criteria, custom rubrics, and safety requirements for your specific use case.
02
Measure
Automated and human evaluation against benchmarks, custom datasets, and production traffic.
03
Analyze
Surface weaknesses, regressions, and gaps across model versions, prompts, and domains.
04
Improve
Drive fine-tuning and RAG optimization from evaluation findings. Track improvement over time.
Who It Is For
Built for every team that ships AI.
Model Developers
Benchmark your models against frontier competitors with expert-curated private datasets. Understand exactly where your model leads and where it falls short before public release.
Enterprise AI Teams
Continuously evaluate your production GenAI applications for accuracy, safety, and reliability. Catch regressions, monitor live traffic, and drive improvement from real data.
