Evaluations overview

How to run evaluation workflows in Evidently Platform.

This documentation section covers how to run evals, whether you're using code or a no-code interface. It also shows you how to explore, compare, and track evaluation results in the Evidently Platform UI.

When you need evals

You need evals at different stages of your AI product development:

When You Need Evals	Example Questions
Ad-hoc analysis. You may run evaluations on the fly whenever you need to troubleshoot an issue or understand a specific trend.	What are the predictions with the highest error? How often do particular topics come up? How does my system perform on adversarial inputs?
Experimenting. During development, you may test different parameters, models, or prompts. Evaluations help you compare outcomes and iterate with confidence.	Does the classification precision and recall improve with iterations? Which prompt delivers more accurate answers? Does switching from GPT to Claude enhance the quality of retrieval?
Regression Testing. When you update a model or make a fix, you need to evaluate its quality on new or previous inputs, often as part of CI/CD pipelines.	Does changing the prompt lead to different answers to previous user queries? What is the quality of my ML model after retraining it on new data?
Online evaluations and monitoring. Once in production, you can automatically assess the live quality of your AI system using incoming data.	Is the environment (input features) changing? Are predictions shifting? How professional and concise were the chatbot’s answers today? Is version A or B performing better in production?

Evidently supports all these workflows.

Evaluation workflow

You perform evaluations by generating Reports or Test Suites using one of these methods:

• Local evaluations using the Python library

• No-code evaluations directly in the UI

Evals in Python

Supported in: Evidently OSS, Evidently Cloud and Evidently Enterprise.

This is perfect for development, CI/CD workflows, or custom evaluation pipelines. Once you run an eval in Python on your dataset, you upload the results to the Evidently Platform.

You get to choose what you upload:

• Results only (Default). You can upload just the evaluation outcomes as JSON snapshots. They include column summaries, metric distributions, and test results. For tabular data, this typically provides the necessary insights while keeping data private.

• Results and Dataset. Alternatively, you can include the dataset along with the evaluation results. This is useful for text data evaluations or whenever you want detailed row-level analysis, like investigating specific completions with low scores.

What’s a snapshot? This is a rich JSON version of the Report or a Test Suite with the results of an individual evaluation run that you upload to the platform.

See how to run local evals in detail:

Generate snapshots

No-code evals

Supported in: Evidently Cloud and Evidently Enterprise.

With no-code evaluations, you work directly in the user interface. This is great for non-technical users or when you prefer to run evaluations on Evidently infrastructure.

Here's what you can do:

• Evaluate uploaded datasets. Run evaluations on collected traces (if you've instrumented your LLM application) or on Datasets you previously uploaded.

• Upload CSV data. Use a drag-and-drop interface to upload CSV files and run evaluations entirely on the Platform.

Once you run the evaluation using a no-code flow, you create the same Report or Test Suite that you would generate using Python.

The rest of the workflow is the same. After you run your evals with any method, you can access the results in the UI, and go to the Explore view for further analysis.

Evaluation results

Supported in: Supported in: Evidently OSS, Evidently Cloud and Evidently Enterprise.

The result of each evaluation is either a Report (when it's just a summary of metrics) or a Test Suite (when it also includes pass/fail results on set conditions).

Browse the results. To access them, enter your Project and navigate to the "Reports" or "Test Suites" section in the left menu. Here, you can view all your evaluation artifacts and browse them by Tags, time, or metadata. You can also download them as HTML or JSON.

To see and compare the evaluation results, click on "Explore" next to the individual Report or Test Suite.

Explore view. You'll get the Report or Test Suite and, if available, the dataset linked to the evaluation.

Supported in: Evidently Cloud and Evidently Enterprise. In Evidently OSS, you can can access only the Report.

• To view the Report only, click on the "dataset" sign at the top to hide the dataset.

• To see results from a specific evaluation within the Report, use the dropdown menu to select the Metric.

• To compare Reports side by side, click on "duplicate snapshot" (this will keep the current Metric in view), and then select a different Report for comparison.

Dashboard. As you run multiple evaluations, you can build a Dashboard to visualize results over time.

Supported in: Supported in: Evidently OSS, Evidently Cloud and Evidently Enterprise.

The Dashboard aggregates data from various Reports or Test Suites within a Project, allowing you to track progress, see performance improvements, and monitor how tests perform over time.
