Automated evaluation
Run automated checks to measure output quality, safety, and reliability, then review results through shareable visual reports.
Evidently AI
Evidently AI is an open-source platform for evaluating and monitoring LLMs, RAG systems, AI agents, and predictive ML models. It helps teams run tests, generate synthetic data, and track production quality with built-in and custom metrics.
Overview
Evidently AI is an open-source AI evaluation and observability platform for LLMs, RAG applications, AI agents, and predictive ML models. The site presents it as a single framework for evaluating, testing, and monitoring AI systems across development and production.
Its core purpose is to help teams check whether AI is safe, reliable, and ready after updates. The product combines automated evaluation, synthetic data generation, and continuous monitoring, with support for visual reports, dashboards, and a library of built-in and custom metrics.
Core capabilities
Synthetic data generation
Generate realistic, edge-case, or adversarial inputs for testing prompts and workflows before or during production use.
Continuous monitoring
Track evaluation results and quality checks over time with a live dashboard to surface drift, regressions, and emerging risks.
Flexible metric framework
Use a library of more than 100 built-in metrics, or combine rules, classifiers, and LLM-based evaluations for custom quality systems.
Coverage for common LLM checks
Evaluate adherence to guidelines, hallucinations and factuality, PII detection, retrieval quality, context relevance, sentiment, toxicity, tone, and trigger words.
Custom evaluation logic
Create custom evaluations with any prompt, model, or rule, which lets teams adapt the framework to different AI products.
Typical use cases
LLM product testing
Evaluate chatbots, copilots, and other LLM-powered products with templates and metrics that cover quality, safety, and factuality.
RAG evaluation
Measure retrieval quality and context relevance for RAG systems, including checks that help identify grounding issues and answer quality problems.
ML production monitoring
Run continuous monitoring for production models to detect drift, regressions, and data quality issues after deployment.
Adversarial testing
Generate edge-case or adversarial test inputs when you need to stress-test prompt handling, safety boundaries, or jailbreak resistance.
Custom AI quality workflows
Build internal evaluation workflows for teams that want custom tests, metrics, and reports rather than a fixed dashboard-only product.
Pros and Cons
Pros
- Covers both LLM and predictive ML use cases in one framework.
- Includes automated evaluation, synthetic data, and ongoing monitoring rather than a single point solution.
- Offers 100+ built-in metrics plus custom evaluation logic.
- Is fully open-source under Apache 2.0, according to the homepage text.
- Provides guidance content and courses that may help teams adopt evaluation and observability workflows.
Cons
- The collected pages do not provide a full integrations list or platform compatibility details.
- Pricing specifics are not shown in the collected text, so buyers cannot confirm plan structure from these pages alone.
FAQ
